Where Anthropic f'ed up was treating their monetization the way they treat model training. Turns out that success in experimentation is not transferrable.
They have tried to find the highest that the market pays for sota models; however, on the consumer side, this is just too confusing and unsettling:
"You can only use Fable for a week as a part of your plan"
"Be ready! You have to start paying per token!"
"Nevermind! we extended it for a couple more weeks"
"Wait, now it's up to half your usage"
"Ok, now its..."
Most people want to not care. We want our AI like electricity -- Kind of just there no matter how easy/hard is for the supply. You don't want your electricity company to be on the brink of cutting you off any second.
That's Anthropic. You don't feel they want to give you a dependable service for an, albeit premium, price. It's a constant bargaining game. That forces people to look beyond the walled garden. There, they find models that are fine... and without the shenanigans.
Yeah, I agree with this. The constant state of "...will the rug be pulled?!?" does discourage relying on it as a model and building a workflow on it. Anthropic used to just be a reliable thing you could play with. Now it's this constant source of anxiety.
It also didn't help that the government yanked it which adds another source of anxiety since OpenAI is on much better terms with the administration and the administration seems corrupt enough that they would mess with Anthropic if they got a big enough donation from OpenAI.
But anyway after Sol entered the picture, I don't think Anthropic can get away with this as much and I also think they're going to face a massive backlash from Max subscribers if they do end up ending the +50% promotion at the end of the month because Sol is a Fable peer and priced very competitively.
As soon as I started using Fable I was like, okay, this is probably as good a model as I will need for software engineering going forward. I still feel that way. I don’t need a better model, I need a faster Fable.
The thing I miss most about programming is flow, and the constant bouncing between terminal tabs sucks. I’d love to do one thing at a time, with Fable, quickly.
I agree they’ve done a bit too many pricing / usage promotions and A/B tests.
The period was also marked with many billing bugs, like spending people’s usage credits for included Fable for a few hours (gave me a huge shock), but to their credit they refunded it.
They are fumbling the bag hard. AI's utility is for general purpose. The floor is rapidly improving from below them. With chatgpt I'm uploading all my day to day stuff. Meanwhile Claude is only for occasional super hard tech problems which are rapidly improving with being solvable easily by Sol. So what's the value add?
Their disrespect for their users is also another problem. You only get one shot to make a good impression.
If I got cut off from asking chatgpt what the status of a spreadsheet is for handling my personal bills due to my rate limit from coding work I would not be coding on it at all. Glad someone over there realized this obvious fact.
As Anthropic does this, OpenAI Is giving everybody resets like every other day now on Twitter.
I'm strongly considering biting the bullet and just ditching my $200/month Claude Code plan for the Codex one instead, especially because I keep running into my weekly limits (even sticking to Opus.)
I don't think Anthropic wants a stable experience on their consumer subscription plans. It is just used for customer acquisition who will then ask their employer to pay for enterprise plan(assuming most employer care about data control) which is based on tokens.
Most coders don't pay for tokens themselves. It's just on reddit and HN you would think that everybody does.
I pay for my tokens for my own projects, at least when the ones Google seems willing to keep throwing at me for free don't cut it. I'd think that's not too uncommon, especially here where there's likely a high ratio of hobby coders (whether also professionals or otherwise).
I would guess that it's hard to compete with Google without a consumer component. Most enterprises already have contracts and policies with Google, so anything driven from the top-down is likely to prefer Google.
(And failing that, there was a real risk for OpenAI to be the default for enterprises.)
To defeat that, you need to frontline employees the chance to experience better tooling and models which is where the subsidized subscriptions come in.
The fact is that demand for tokens at electric bill rates so far outstrips what can be supplied currently not just with frontier models, but with open weights cheap models too. Running an always on Deepseek flash agent would cost three figures a month at API prices.
Total costs sure, electricity only costs no. My two DGX Sparks run DS4 Flash at about 50tok/s concurrency=1 which is more than suitable; at about 150W total wall power when generating.
That’s about A$16 a month in electricity if I ran it 7x24x30.
Mythos? That's only for super special corporations, you need not apply. Fable? Can't even look at it wrong without running into cybersecurity lockouts. And even if you get past this, it's limited to <50% usage. It took me a month to complete a Fable review on my project.
So stingy. Even with OpenAI's recent usage troubles, they're still so much better than Anthropic it's not even funny. Re-ran the code review with Sol as a benchmark and it turns out Sol's performance is within 70%-90% of Fable's. Anthropic's still got the best model, but what does it matter if I can barely use it?
They've put themselves in a corner. Fable was too good and they gave it away with the $20 plan. It had to be a big step from Opus 4.8 to show progress, and Opus 4.8 is GREAT at coding in many different domains.
But they're getting killed on token cost. They have to get people paying more for tokens. So then they put Fable in the $200 plan and release Opus 5. I'm suspicious of Opus 5. It is mostly worse than 4.8. It _seems_ like they nerfed it to create more distance between it and Fable.
So what have most of us done? Stayed on Opus 4.8. The statistics bear this out. 4.8 still dominates.
Now they're stuck. If they take 4.8 away, everyone will riot. If they make Opus 5.x better than 4.8, they disincentivize everyone from moving to Fable and most importantly, paying more.
Really, all they can do is take the L for now and just let 4.8 be the apex of the $20 pro plan for the foreseeable future while they work like hell to make Fable THAT much better that it earns the $200 to $infinity that they really want everyone to pay.
I kind of still chill out on Opus 4.6 too. 4.8 is good too. I go between them. Opus 4.8 is a little smarter some of the time. Their use of language is both very different from Opus 5. Some of the time I have a hard time believing Opus 5 is even related to Opus 4.6 and 4.8.
I'm going to be sad when they retire 4.6. It's not my daily driver but it's still my go-to when the other models are being stupid in one way or another (either being too verbose, or lecturing me about how what I'm asking for is evil and bad).
That seems about right. 4.8 is like in between 4.6 and 5 in terms of capability and language and they are all pretty close honestly. I just default to using Opus 5 for a coding agent that I don't interact with and I like driving with Opus 4.6 or Fable. Fable thinks too much though. Fable is like that engineer on your team that will over-engineer the shit out of something if you let them. Fable was like, "Here are 34 yaks, which shall we shave first <hands rubbing together>" and I was like can't we just... write the script first and then decide of any of these poor yaks need shaving?
And they've hobble Fable and Opus so hard with their safety guardrails, I ask innocuous questions and tasks and they get flagged so often I gave up on it. I can get all the work I need done in GPT5.5 or 5.6 without the hassle.
Yeah same. Multiple 20x max accounts, I typically hit > 50% of the fable usage limit on eace, literally never seen a guardrail. Maybe I’m boring? Maybe they have some kind of account reputation system?
I hit it once when I asked a question about whether butterflies remember anything from their time as caterpillars. I've never hit it for coding, but I also don't really do much related to security.
The other thing I forgot to mention about Opus 5 is that at least out of the gate, it seemed very intent on spinning up agents and obliterating my token budget. It was noticeably more token hungry than 4.8. It would make sense for them to intend this behavior.
Also on a dark reader? It says at the bottom, but gets dimmed out pretty seriously with dark reading. It's a 7 day average business spend, relative to June 1st (2025 presumably) indexed at 100.
Might as well not be - I routinely get rate limited in a single review session.
I've honestly stopped using CC and moved to codex. Sol has it's warts but I've never once hit limits on a 100€ and I get a similar level of performance for what I'm doing.
I wouldn't mind bumping Fable to 200$ plan if it was actually better but between the insane caps, reverting to opus/sonnet randomly and having similar perf as OAI - I'm done with it.
Next step is to put 100$ into open router and try some western hosted open models with Pi when OAI starts pulling up prices.
I did not know that - but what happens then I get denied and I plead with the model that my usecase doesn't violate its TOS ? Edit prompt till I get it to pass ?
Reverting is annoying but being flagged for security questions while I'm doing code review is insane.
Yes, you get to re-try it until it might pass. Each attempt uses tokens at Fable level though. I once burned through a 4 hour window ($20 plan) in 4 attempts to re-frame the request.
You want to disable "Switch models when a message is flagged"[1]
Yeah for me Fable works great on the $100 plan. The problem with Fable is you will hit the weekly limit. The $200 plan does not give you 4x or even 2x the weekly limit. For me i only get about 1.3x weekly quota, so I don’t think it’s worth it.
I still havent used it much, and they crippled Opus for what feels like no reason. Some suspect that Opus knowing theres a better model degrades it some. Shame.
Of course I echo the universal: Opus 5 sucks. But what also sucks is still using 4.8. Are you all seeing this? It's like the older models got dumber just before Fable and Opus 5 were coming out? I've heard the theory that it's because 4.8 is getting put on older hardware? And I imagine that just ratchets down reasoning time then possibly?
Sometimes I'm just trying to sus out if I'm truly seeing things these days or going a little nuts :)
I definitely agree. I honestly cannot do tasks that require even minor complexity. Opus 5 keeps forgetting things in context as well and coding conventions. Really cannot build with CC without Fable.
This is yet another reason why I think local models will win in the future. They're almost certainly A/B testing all sorts of opaque stuff that people have no clue about, hence the various 'How's Claude doing this session?' popups.
So what you are paying for may vary on a day by day basis, which is quite undesirable, even if their main goal is simply to make a better model. When it comes to a tool, I'd rather have consistent mediocrity than instability.
I'm not an expert by any means whatsoever but deploying models is not a straightforward task. There's a lot of levers to pull and I bet when models get "downgraded" to older hardware they do so WITHOUT the same stringent quality control of the output as they do when they release it.
I don't think it's something deliberately malicious like planned obsolescence but it's more like startup culture of "just make it fit in this sprint".
For many coders including myself, LLM based coding agents work well enough to be useful, and in some cases worth paying for.
What I don't see is vast areas of industry finding $10s to $100s of billions of value in LLMs. There's no lint or compiler that can check for correctly constructed contracts. So LLMs, which should be useful to law firms, incur a lot more manual checking of their work than coding agents.
Less formal document production in other industries is likely to have less structure. That might not matter in some settings but I'm having trouble thinking of an example off the top of my head.
My company still hasn’t been able to deploy wide access to Fable because it’s not available on a ZDR basis. This wasn’t mentioned in the article but I imagine this factor is not irrelevant.
It’s far from clear to me that this is directly connected to the no-ZDR requirement. I’m heavily involved in this stuff with my company and I’ve never heard that the lack of ZDR fable is a Trump admin thing.
Transformer models are quickly becoming a commodity, and I suspect in time we'll all be running them locally. Even now, you can run something pretty useful on a 16 GB graphics card, and I suspect a decade into the future, entry level hardware will be running better models than high-end graphics cards can run now, as entry-level hardware gets better and models get more efficient.
It doesn't mean hosted frontier models wont exist, they'll just be rare. It's no different than any other commodity market, for example most cars are cheap commodity models, with rare individuals buying expensive luxury cars and businesses buying expensive trucks and specialized equipment.
This is really it for me as well. At the heights of complexity AI can do magical things. But really a lot of the time I just want it to do mundane things right. And currently it just cannot. It writes garbage text, consistently ignores something you have told it, makes mistakes a human makes once but the AI remains uncorrectable.
Dijkstra in the Foolishness of Natural Language Programming
[...] the "naturalness" with which we use our native tongues boils down to the ease with which we can use them for making statements the nonsense of which is not obvious. It may be illuminating to try to imagine what would have happened if, right from the start our native tongue would have been the only vehicle for the input into and the output from our information processing equipment. My considered guess is that history would, in a sense, have repeated itself, and that computer science would consist mainly of the indeed black art how to bootstrap from there to a sufficiently well-defined formal system.
Imagine if only we had languages at our fingertips whose explicit purpose was to precisely and unambiguously tell a machine what to do!
I’m not sure if the underlying data is counting subscription use for Fable, which is where a lot of people are using it because token pricing is very expensive. I wouldn’t be surprised if this was counting enterprise token usage only. As rich as enterprise customers are, they’re not exactly willing to double the cost of SWE salaries on tokens.
Either way, a model used to solve the top 10% of problems that people use AI to solve for, being used 10% of the time … seems like it’s in a decent place.
I find Fable indispensable, and measurably better than alternative models, for complex feature development in an existing codebase. It’s the closest thing I’ve seen to nearly one-shotting features. Even still, I only use it for the hardest features and Opus 5 does a good enough job on the rest.
Very much agree on Fable. Over the past month or so it has shown to be the only Anthropic model that can understand a largish dbt model codebase. Opus 5 gets almost everything wrong. (High reasoning on both)
More importantly other way cheaper models can do what Opus 5 does. So you can pay for Claude to use Fable 5 exclusively for harder stuff and planning, then get the same value you'd otherwise get from switching back to Opus by using other cheap LLMs for day-to-day coding tasks.
Yeah as soon as CFOs realized AI was racing to become one of the most expensive line items along with salaries and AWS bills, they started cracking down on the most expensive ones.
The US government basically told them they can't sell "Fable" and so they aren't. That's probably 90% of the story.
Once the government stepped in, their 5th generation was effectively killed. They either had to lock it up (Mythos), neuter it (Fable), or leave people with the perception they were overpaying for a weaker model (Opus 5).
Hopefully Anthropic has learned to anticipate this risk and has a plan for rollout of their next model that plans for capricious ad-hoc regulation.
I am getting close to dumping Anthropic. I like their models in general, but boy I have hit their "F you, I ain't gonna help" too many times now on innocent things. Ain't nobody wanna deal with that. I have never gotten that from Antigravity and if I did I woupd tey Codex then go to Openrouter and leave US models behind.
I mean, who says "screw you" to requests to get 35+ year old vintage computers working? Claude, that is who. Its guard rails are so stupid. I hear people trying to do simple mailing list management hit it too.
Like 90% of consumer AI use is stuff like "please write a summary of this PDF for me", or "Find a cheaper version of this product online", eventually the returns on model intelligence taper off for these kinds of tasks. However for the kind of frontier tasks they are testing the models on now, like math, science, etc. the marginal returns on increased intelligence are huge.
Fable is just way too expensive and limited compared to GPT 5.6 Sol, and the only task that requires that level of intelligence is frontier scientific research. I use GPT/Codex primarily for coding and usually keep Claude on Sonnet 5 most of the time as I use Claude primarily to debug/brainstorm/make frontends as a supplement to GPT.
I do not agree. Fable is the only model I can leave unattended and give me results for part of my work which is just devops related tasking.
I can hand hold opus but I would rather just ask fable to do it and give me the result that I review and works. Opus will waste tokens and still require me to help nudge it in the right directions.
I think the next gen models from china will put us in a spot that the cost can plummet and I won’t need the Sota from anthropic
I second the parent comment. 5.6 sol xhigh is not only better than fable I can also run it forever without worrying about limits. The frontend has gotten much better too with the plugins that come with codex.
Agreed. I have the highest individual plan for both. I run out of Fable credits midweek, while I usually have some credit with Chatgpt left despite it having to carry Fables load for the second half of the week.
Also, Sol doesn't refuse constantly and speaks like an engineer rather than a deranged academic.
Opus 5 is legitimately terrible and can't or won't follow instructions. It is of negative utility and does more harm than good to my codebase.
In a frontier scientific research environment, funding is often limited, so personal subscriptions are more common. Fable can hit a 5-hour usage limit on the Max subscription tier before it finishes a single complex math prompt. Most of the time you get one or two if you reduce context and question complexity. Most of my colleagues are cancelling their subscriptions because of that, and just using Sol instead, which is virtually unlimited on the Pro tier.
Hmm. Would you mind sharing an example of a complex math prompt that you would use? Because I found that even Sonnet can solve fairly complex math problems fairly easily if you give it the right tools, so I'd like to give it a shot myself if you'd like.
Most of the benchmarks have exceeded their usefulness. Opus 5 beats fable 5 on many of them. Anyone who has used both models will notice immediately that this doesn't translate to the real world. Opus 5 is nothing short of a regression from Opus 4.8. Fable is genuinely a great model so long as you don't trigger a guard rail and it downgrades.
Sol in my experience isn't significantly different than fable ignoring that Sol burns usage 10x faster but the end result is hard to differentiate.
GLM 5.3 is a hair behind these two.
An anecdote but not an original one from the people I talk to.
Sol routinely catches stuff in review that fable misses for me. It's impossible to compare them meaningfully because it's a complete dice roll - but in practice using both in my projects I can get work done with both, and Opus 5 is far more tedious.
But Fable security false positives and pricing just make it not worth compared to Sol IMO.
Yeah, it's pretty much apples to oranges, and I don't consider GPT and Claude to be interchangeable at all. From my anecdotal experience, GPTs generally codes more creatively and verbosely but Claudes tend to code more carefully and precisely, so the result is that GPTs generally finds more creative solutions to problems but also writes buggier code, which is why I converged on the setup of GPT/Codex for implementation and Claude for debugging, which feels more like a force multiplier than using each model individually.
I have 200MAX subscription for Anthropic and a RTX 5070TI 16gb GPU. I only use Claude.AI web chat and I only use Opus4.7. I build my prompts on prem with Qwen3.8:latest and copy paste them in claude.ai. I never type anything into claude.ai I am merely a copy pasting monkey. If I need to adjust something I do it from the the on prem prompt. I download code bundles from Claude.AI and push them to my git repo I host. I instruct claude to not do any testing and only let me do testing on my machine so i am not wasting claude resources. The point is to minimize the claude agents from doing anything but specifically doing coding. I can do this for 12 hours a day and reach about 80% of my weekly usage. Once I get to 3 hours left on my weekly I start a fresh chat session with Fable5 and have it do blind code reviews on everything. I only do this because I want to max out my weekly allotment and fable will get me to 20% in 3 hours on a 200MAX sub. Sometimes Fable5 does something interesting but for the most part my on prem static and dynamic code analysis have kept everything buttoned up.
Fable is not used because it has extra retention requirement that corps can't sign off so it stays disabled for everybody in many cases.
It's also not winning on day to day work against Opus 5, which is simply available as there are no extra retention requirements and no extra paper work to do with legal.
Devs also don't like that Fable refuses to work on half of their prompts.
Then comes better pricing and on-par capabilities from competition.
With open models delivering close to frontier level capability, I really don't see how these labs can only focus on having best model to sustain their business. Although these model's usage will grow, I think and hope that the serving will be distributed among many players.
In my opinion, the big issue with Fable is that Claude Code cannot use it properly. I know, that sounds weird, but I've had Fable run down the wrong lane (and never stop) or give up and claim that something was impossible so many times (until I pointed at a GitHub repo that solves the "impossible" issue).
But a while ago, I had access to a Fable harness that just never gives up. And that verifies itself. It burned $100 in API tokens in 15 minutes ... but it succeeded for all the prompts where Fable + Claude had failed.
And I believe that's a real issue for Anthropic. Fable+Claude is not too expensive thanks to the subscription, but Claude severely nerfs Fable. To save money, I guess. Fable API + Custom Harness is a different class, it's so much better. But API tokens are so expensive, you're cheaper off hiring a freelancer.
People here won't believe this, but Anthropic will begin to decline after their IPO when everyone runs to good enough cheaper models to save on token spend.
I wish Fable were as good as you make it sound. A plan created by Fable is good, but in my case, it always contain issues caught only when it's reviewed again (whether by itself, Opus, Sol etc.). That's (almost) not different from plans created by Sol, GLM 5.3 etc. The one thing where it's genuinely better is the front-end, but then again it's far from perfect, it just needs less iterations.
>> but in my case, it always contain issues caught only when it's reviewed again
Yes but those issues will be much less severe with Fable-written plans than those written by lesser models. I know this because my workflows at both my regular job and my startup involve multi-step agent reviews via codified adversarial review skills. Fable as a reviewer will frequently find blocker-level issues with plans written by GPT 5.6 Sol, and sometimes with Opus 5. The opposite almost never happens. In fact I cannot remember the last time it happened.
I have a sneaking suspicion that someone at Google may be making the same bet, looking at the faster and faster Flash models which provide acceptable results to a lot of people (outside of coding).
For Anthropic. But not for the AI industry at large.
Cheaper, more powerful AI will continue to expand the bubble. Projects will get more ambitious. Everyone will build out their own custom little software. Code diversity expands and requires even more AI.
The bubble is _not_ on models becoming more intelligent and solving arc-agi-999.
They are already good enough at what they mechanically are.
You have to use the right harness, right verifiers (automatic where possible, human where not), etc much much more specific than a generic one like claude code or codex, and it will also be able to work within constraints and be the "proposer" of an imaginary optimisation problem and an excellent one at that. But you have to frame the task at hand in that manner or maybe even reorganise the task you do itself so it is more amenable to being framed that way. If you use it this way, it is _already_ massively economically useful. But it will take many years for it to actually be usable in that way, since you need DC capacity to come up first which is few years away and also well, massive organisations that have to integrate these will usually take many years to do so.
It is also useful albeit less so in cases like general SWE, where you still need a human in a loop for non-verifiable requirements, and also in other general usecases where information retrieval is too intractable and you need to carefully use LLMs as a component of the overall system.
I am not saying Fable or whatever the biggest models are are useless - they will certainly be useful for tasks at the frontier of the day - which is today complex exploits and open math problems, and well, tomorrow it could be something in biotech. But this is not what the entire bet is on at all - just automating day to day drudge at the tens of thousands of massive companies and governments we all know and love is more than enough. With the right training data (which _also_ is a bottleneck and takes time) you could even automate certain processes entirely. Sure, if we get a crazy medical innovation and end up saving trillions in healthcare great, but that's just a bonus.
None of this is to say that I think there is zero sketchy financial engineering going on
The bubble is based on the promise that these LLMs will cure cancer and find the solution to global warming. The pragmatic users of these tools (like you seem to be) are enjoying the subsidized use of the tools right now, but it's not a sustainable business model
The issue is that, if there is a “good enough” point approximately here, it is only a matter of time before models become small and efficient enough not to need all those data centers. Though, it should be good for companies that sell computers (like Apple) rather than putting a toll booth in front of a pile of numbers.
I think highly complex work and “professional” work are basically completely orthogonal. You can have highly complex work you do as an amateur, where AI can be very useful. For example working through a difficult mathematical problem, building or contributing to an operating systems, or researching a highly technical topic for a hobby project such as microscopy, chip design or lithography.
And you can have extremely simple work that you nevertheless have to do as a professional. For example, drafting a routine customer email, summarizing a meeting, formatting a report, filling in standard documentation, or making a trivial code change.
So I don't think the $15k workstation / professional camera analogy really holds. Those are specialized tools whose capabilities are mostly useful within a fairly narrow domain. A general-purpose AI can be useful across thousands of completely unrelated tasks, including one-off problems encountered by ordinary people.
GLM series has made it very practical to self host. If the new update for Deepseek flash holds up, I think it would be silly for some companies to not self host.
Anthropic’s issue is churn because of the peak verbosity vomit coming out of Opus 5/Mythos/Fable. What the hell did they train it on. The sane model is still Opus 4.6.
- Opus 4.6 was the last Opus generation that got a lot of use by Anthropic's own employees
- After that they primarily used Mythos internally
- 4.7, 4.8 and 5 were RLAIFd by Mythos "teachers"
- Hence why 4.6 is the last Opus gen who doesn't report back like a robot wanting to cover every potential hole another AI system would've spotted and criticized
- Hence why coding style in Opus 5 also gets criticized, not only behavior in CC
Commented elsewhere, I still use Opus 4.6 because it is the only model that feels decent to interact with. 4.8 is decent and some times smarter but you can see it trending towards Opus 5 levels of nonsense. I use Opus 5 when I don't need to interact. Fable or Opus 4.6 are the only Anthropic models I like interacting with ATM.
Opus 5 is by far the best model for everything that matters to me. But it’s just too expensive. Terra 5.6 is bearable for everyday tasks, so now it’s my default.
1. They acted as if they were so far ahead capability wise that they could stop listening to their users.
That is basically it. It is an extremely common belief that Opus 5 acts like a condescending wannabe-thought-leader, yet Anthropic's response to this is largely been "You're using it wrong. Try deleting all your config files".
They released a "concise" output format, but pretty much swept it under the rug, despite it being one of the loudest complaints about their models. It also, generally, does not work as described.
Not only did Opus 5 get much more difficult to work with, but it got, from a customer view, significantly slower. The token rate might be the same, but if every interaction takes 50% more tokens, it's 50% slower.
All this time OpenAI has released a slew of new models, lowered the price on them (which, bluntly, 80% of user count don't actually care about since they're on subscriptions), increased subscription capacity, and increased response speed.
It's not about cost. It's about Anthropic being the frontier-lab version of the marathon runner who decides to celebrate to early, and then loses the race.
I have a $20/mo subscription and have found myself getting limited every few minutes of late. I'm just building a simple website, but after about 15-20 mins of back-and-forth, it tells me I'm tapped out for another 5 hours.
This wouldn't be so bad if it didn't make mistakes periodically, especially when it's about to tap out. I get the sense that if I upgraded to the $200 subscription it would get me a lot more usage, but it would still run into these issues anytime I sat down to work for a few hours.
I'm just using medium effort, so it's not like I'm on high all the time.
As a small background, I have a local server and I've been trying out different models with different inference engines, quants, configurations etc... I'm also using Opus and Sol at work consistently. I've used AI since the first wave, first as a toy, then as a highly specific tool, last 6+ months as the primary LoC generator.
This is the first time I've felt, and I use the word *felt* since I don't have a suite of benchmarks or any sort of material approach towards comparing models, that Opus has declined in quality compared to before. Primarily I think its powers of deduction and understanding, even on xhigh, have become much worse. Before, being vague and providing a simple prompt would be enough, it could deduce and expand the details it needed, plus ask you clarifying questions, now this is no longer the case. A concrete, personal example, for a personal project, I've asked it to setup ssl over local IP. I didn't go into too much detail in the prompt as there are many approaches it could take and I didn't care too much to choose. It did horrible. The first thing it did was say the best lightweight approach is to add a reverse proxy. I'm like ok, makes sense. Then after asking it to proceed, it went and added a bunch of config to my golang service and didn't even setup a reverse proxy even when it said that is the way to go. It even said it didn't set it up lol. Then after I told it to do so it failed building the config in a way it was asked of it (support LAN IP and tailscale IP). Etc etc...
When Fable came out it was huge, the benchmarks told the story, and the story mostly matched the experience. It felt, again, intentionally saying felt, like it was miles ahead. Now benchmarks say that there are many models that are close, but in actual use Fable still *feels* much better. I think benchmaxxing the new open weights models is ruining the value of benchmarks, if they ever had any. When you actually put them to the test you see 500k tokens of reasoning with "Actually..." and "Wait..." in every third paragraph of their reasoning trace.
The price for Fable is definitely too much for any personal use now that it's no longer included in the subscription, and GLM 5.2, Deepseek Flash and Qwen 3.8 served locally or via cloud provide a lot, requiring a bit more babysitting though. Considering the price of Fable, my 5k USD Epyc server would pay itself off in less than a year if I used Fable or Opus in the same manner so at least for me the decision seems easy. And considering the point I'm poorly trying to make, that Opus doesn't feel like frontier anymore, this is probably the last month of my Claude subscription.

I've wondered if this is part of why we don't see the reasoning traces for Anthropic's models before -- Open models might just be accurately surfacing how the sausage is made.
Hasn't it always been the premise that intelligence would get cheaper? To me, on the enterprise side, it seems like firms are finally getting the memo that, whether you are locked into the Ant/OAI ecosystem or not, you don't need the smartest, most expensive model to do every single task. This is a good thing for overall adoption. Whether that trickles down into regular user behavior, especially with subscription pricing, remains to be seen; even though I intellectually know I don't need Sol for a simple refactor, I am sometimes hesitant to choose Luna/Terra, as it's hard to accept using something positioned, even implicitly, as 'worse'. Remembering that the smaller models tend to be faster is what usually pushes me over the edge.
Anthropic in particular is much more compute-constrained than OpenAI and SpaceXAI and has relied on partnerships to provide inference. This reality factors into their pricing and usage limits (they started 'adjusting' the 5-hour limits during peak hours, and it certainly wasn't an upward adjustment). Accordingly, this is presumably what Anthropic wants, given they develop and release the lower-end models, suggest users use them in various nudges within their product, position the bigger/more expensive models as "For the most complex tasks" in their UIs, and so on.
> whether you are locked into the Ant/OAI ecosystem or not
I think the problem (for Ant/OAI) is that there is no sensible lockin or moat. LLMs are essentially interchangeable and stuff like a harness doesn't offer enough value on its own for someone to be locked into using one of them.
Now with the onslaught of the Chinese models that offer almost the same quality for much less money they have a very serious problem on how to proceed. Investors now might be looking through rose tinted glasses but their patience has its limits.
Agreed 100% for the consumer case: an empty chatbox is just about the least sticky surface I could ever imagine. I saw a mobile interstitial ad for Kimi recently whose hook was basically "Tired of paying for expensive ChatGPT? Download the Kimi app, it's the same thing but cheaper". I myself bounce between token subscriptions like no one's business and use Pi/OMP for maximum model flexibility when coding (and it's a few env variables or lines of (TO|YA)ML|JSON to switch providers in Codex, Grok Build, CC). I even self-host and try to use OpenWebUI + CLIProxyAPI when I can for all my chats.
Enterprise is a whole different ballgame IMO with countless technical, compliance, and employee adoption considerations that add friction to switching. It's also where both Anthropic and (as of last week) OpenAI get the bulk of their revenue, and, incidentally, the venue where US Government regulations on Chinese models would have the most impact.
Honestly, this makes a lot of sense to me. Devs that are good at their job don't need the absolute best model for every task, and if a cheaper model gets the job done 95% as well, it's a pretty easy choice
Perhaps nerfing the cap out of your best model for press attention and hosting valuable features like thought traces isn’t such a great business model?
Are we at the stage yet where a super-strong model that needs oodles of safety protections to stop it outright hacking you is strictly worse for day-to-day tasks than a much cheaper model that's simply not competent enough to be dangerous?
A model is just another thing to plugin to a harness. I don't give it much more thought than that. If developers are still caught up on Claude Code, or Codex that's just not a long term thing. It's best to develop workflows locally and in the cloud with open harnesses. I know this will be the future because that's how it worked on every other system that developers use.
Sure there are Microslop and Oracle db users but most of the world we live in is Postgres and Linux. That's why I think most companies will run llm's like that.
That’s not true. Before AI, I have been using Jetbrains IDEs as far as I can remember. Also have been using MacBooks for work since my first job. You don’t have to generalise everything. If a particular specialised tool is good at its job just use it instead of re-inventing the wheel
> good at its job just use it instead of re-inventing the wheel
Exactly why is everyone reinventing a harness every month. There will be Microslop / Oracle harnesses and there will be 1 or 2 open source ones that win.
I see variations of this post all over X. Fable doesn't get much usage, since Opus 5 is like 99% as good at a lower price point. And perhaps more importantly also faster.
im using fable almost exclusively, i just buy a new 200$ license if i run out of capacity. its so much better, easily worth it given how much work I get done. I built a code, deploy, e2e test loop with my full aws infra, fable just implements linear tasks constantly, 5 at a time, tests the whole thing end to end
if people dont see why they need a model this smart, they probably arent using ai enough
People have realized you don't always need a Fable level model. Majority of my work is sufficient with ChatGPT Luna which has effectively unlimited usage on the $100 ChatGPT plan.
I am not doing awfully complex tasks though. I imagine a lot of other people are in a similar boat, either switching from Claude to ChatGPT or even just min-maxing DeepSeek V4 Flash 0731 or similar.
Yeah I mean if I run out of tokens every couple of hours and have to pause my work or shell out more money I’ll switch to other tools that don’t have this problem. Though they turned this down a bit it seems, I can work with Fable reasonably now and I enjoy it actually. I think they were just testing out how much they can raise the cost without users leaving when having the best model. I guess not much after all!
Reads like: brilliant Carnegie Mellon University computer science grad struggles to find job where he is not replaced by cheap, inferior Indian labor that still gets the job done, even if it takes marginally longer.
No shit we're all paying 清冲 Flash to do the grunt work. Turns out though, paying 清冲 Flash a few more cents does exactly what Ivy Wasp Pro Mythical does. Crazy how that works.
I've always wondered why everyone flocks to SV's latest darling company. Have we not learned from our history of glorifying these SV darlings that turn hostile?
Most of the people pushing this are just hoping that they can cash out before the hype pops and financial gravity crashes the party. Sam Altman recently claiming that the singularity is here is so stupid on its face he should just be treated as what he is, a huckster.
None of this stuff ever made any sense on what it was being sold initially. It was always insulting that the media and business leaders tried to argue that the tech could replace entire call centers or vast swaths of entire industries.
People keep arguing, but it will or it has based on extrapolating certain, reasonable use cases. Klarna has shut up about replacing call centers with bots because Markov chains with memory only can do so much.
Some of us want to get work done and don’t feel the need to either glorify or hypothesize about what might happen.
I’m happy with Claude. If they become (bigger) jerks, I’ll switch to something else. I don’t ha e the energy to praise Anthropic today and I won’t have the energy to demonize them tomorrow. The emotional investment people have for/against these companies feels like celebrating or being offended by the weather.
A mixture of opportunistic edge-seeking, FUD, FOMO, novelty-seeking, the need to impress shareholders, the tendency of salespeople to believe other salespeople are telling the truth, the ever-present need to stay in front of relentless commodification, and pragmatic curiosity.
TBH I don't think any of that is unique to the IT industry's relationship with the Valley. Other technology-driven industries have a similar worship-ish relationship with a few rarified businesses. But the culture of the IPO exit accelerates all the most short-term motivations to do anything.
I am because Claude has figured out I am a biochemist and therefore even asking Fable what the weather is gets me bumped back to Opus, sometimes even Opus 4.8 instead of 5. Kimi? GLM 5.3? DeepSeek? No such problem.
I can literally open a new chat with just "Hello" and it gets bumped.
Memories break Fable 5 for me as well in chatbot. I ask Opus a lot of sec related stuff and now if I even type “hello” in chat it gets insta-downgraded to Opus 5.
Claude keeps track of memory if you've turned that on so all conversations are somehow tracked over time Claude randomly will mention that I'm a developer while I'm asking unrelated questions and say oh because you're a developer you might like this or because of my background and infrastructure you might find this interesting and I always get creeped out by it.
They have the concept of incognito chats, but I can see those being worse without context from other conversations happening.
it's not 'somehow'. In Claude Code, type /memory to be able to edit the memory files if you've turned that feature on. If you're a biochemical weapons researcher who has somehow managed to both turn the feature on and fill up the memory with attempted biological weapons research, you can (a) turn that off or (b) go and edit the files to remove objectionable lines of attack.
Regardless, the number of innocent biochemists who have been hamstrung by Fable is essentially zero (but somehow they have all shown up on Hacker News to decry Fable), and the number of non-innocent would-be-biochemists who would love to have unrestricted Fable help them with their non-innocent biochemical research is absolutely greater than zero.
It has figured it out through the software that I work on, data that I analyze, questions I ask, etc. I guess I can't prove it's because I'm a biochemist, but that's the only thing that makes any sense. Either way it won't let me use Fable.
Just cancelled my Claude subscription and used Ox Alpha Free through OpenCode (so that's one).
In my view, from the testing I did since Thursday, it's better than Fable. I had just finished a rather large task that Fable completed, including a /review and an /ultrareview.
Ox Alpha found bugs that Fable and Opus missed, and it continued to build things like a pro.
It does have issues with availability - but it's on a free promo right now. That also means that I don't know how much it would have cost if I had to pay API prices for it, which might not be cheaper than the subsidized small company / consumer usage, but for large companies paying API prices for either offering, the difference will be considerable.
I almost feel like there's some sort of paid campaign going on in Hacker News promoting the Chinese/open models. I feel like every day I'm hearing about how the frontier labs are dead but your experience is the same as mine. My company pays for Claude AND Codex but we never really use the open models for anything critical.
Sure, I'm being "paid" by the fact that it costs pennies a day to use Deepseek and if I could afford the hardware then I could run it locally. Meanwhile, Anthropic is obviously a threat to open weight models and actively lobbies the US Government to have them banned or controlled.
So yeah, I and I guess others, are quite active in whatever little way we have available, to up vote new models and share stories.
Doesn’t matter if your company pays for Claude, Anthropic and OpenAI valuations and expenditures commitment requires them to win the vast majority of the market to make economical sense. And the Chinese competition makes that very unlikely, to say the least. They likely won’t disappear fully but their “free” lunch as the AI darlings is done, on paper. Will be interesting to see how they adapt
It's absolutely a campaign. Every time anyone says anything about Claude, immediately and inorganically there's a bunch of people claiming to be biochemists who are constantly shut down by their work, people saying that they run out of tokens instantly even on Premium, people saying they get even better results on their GTX 4050, and people saying that Grok is better, or OpenAI is better. It's probably several different campaigns each run by different tranches of the competition. Reminds me of the good old days in which every criticism of bitcoin was immediately jumped on by nine or ten pretend Venezuelans who asserted that it was the only thing permitting their family to evade government currency controls.
They have tried to find the highest that the market pays for sota models; however, on the consumer side, this is just too confusing and unsettling:
"You can only use Fable for a week as a part of your plan" "Be ready! You have to start paying per token!" "Nevermind! we extended it for a couple more weeks" "Wait, now it's up to half your usage" "Ok, now its..."
Most people want to not care. We want our AI like electricity -- Kind of just there no matter how easy/hard is for the supply. You don't want your electricity company to be on the brink of cutting you off any second.
That's Anthropic. You don't feel they want to give you a dependable service for an, albeit premium, price. It's a constant bargaining game. That forces people to look beyond the walled garden. There, they find models that are fine... and without the shenanigans.
It also didn't help that the government yanked it which adds another source of anxiety since OpenAI is on much better terms with the administration and the administration seems corrupt enough that they would mess with Anthropic if they got a big enough donation from OpenAI.
But anyway after Sol entered the picture, I don't think Anthropic can get away with this as much and I also think they're going to face a massive backlash from Max subscribers if they do end up ending the +50% promotion at the end of the month because Sol is a Fable peer and priced very competitively.
The thing I miss most about programming is flow, and the constant bouncing between terminal tabs sucks. I’d love to do one thing at a time, with Fable, quickly.
The period was also marked with many billing bugs, like spending people’s usage credits for included Fable for a few hours (gave me a huge shock), but to their credit they refunded it.
Their disrespect for their users is also another problem. You only get one shot to make a good impression.
Same, it's been a while since I logged into Claude web.
ChatGPT web usage being separate from Codex usage limit is a nice touch unlike Claude.
I'm strongly considering biting the bullet and just ditching my $200/month Claude Code plan for the Codex one instead, especially because I keep running into my weekly limits (even sticking to Opus.)
Most coders don't pay for tokens themselves. It's just on reddit and HN you would think that everybody does.
In my company the average claude token usage is something like $5k/month/employee. Most hobby coders don't spend anywhere close to it.
(And failing that, there was a real risk for OpenAI to be the default for enterprises.)
To defeat that, you need to frontline employees the chance to experience better tooling and models which is where the subsidized subscriptions come in.
That’s about A$16 a month in electricity if I ran it 7x24x30.
So stingy. Even with OpenAI's recent usage troubles, they're still so much better than Anthropic it's not even funny. Re-ran the code review with Sol as a benchmark and it turns out Sol's performance is within 70%-90% of Fable's. Anthropic's still got the best model, but what does it matter if I can barely use it?
But they're getting killed on token cost. They have to get people paying more for tokens. So then they put Fable in the $200 plan and release Opus 5. I'm suspicious of Opus 5. It is mostly worse than 4.8. It _seems_ like they nerfed it to create more distance between it and Fable.
So what have most of us done? Stayed on Opus 4.8. The statistics bear this out. 4.8 still dominates.
Now they're stuck. If they take 4.8 away, everyone will riot. If they make Opus 5.x better than 4.8, they disincentivize everyone from moving to Fable and most importantly, paying more.
Really, all they can do is take the L for now and just let 4.8 be the apex of the $20 pro plan for the foreseeable future while they work like hell to make Fable THAT much better that it earns the $200 to $infinity that they really want everyone to pay.
I just kept a $20 plan going for use on my phone.
I don’t doubt people are hitting it… shrugs
Nowadays Codex handles the bulk of the implementation and Fable/Opus on the planning.
Not sure if Anthropic patched it, but early on its release the web UI Fable guardrails will trip if you mention you're a biologist.
2nd time was literally me being lazy and telling it to commit and open a PR.
Very strange.
Where can I find these stats?
I've honestly stopped using CC and moved to codex. Sol has it's warts but I've never once hit limits on a 100€ and I get a similar level of performance for what I'm doing.
I wouldn't mind bumping Fable to 200$ plan if it was actually better but between the insane caps, reverting to opus/sonnet randomly and having similar perf as OAI - I'm done with it.
Next step is to put 100$ into open router and try some western hosted open models with Pi when OAI starts pulling up prices.
Reverting is annoying but being flagged for security questions while I'm doing code review is insane.
You want to disable "Switch models when a message is flagged"[1]

Sometimes I'm just trying to sus out if I'm truly seeing things these days or going a little nuts :)
So what you are paying for may vary on a day by day basis, which is quite undesirable, even if their main goal is simply to make a better model. When it comes to a tool, I'd rather have consistent mediocrity than instability.
I don't think it's something deliberately malicious like planned obsolescence but it's more like startup culture of "just make it fit in this sprint".
What I don't see is vast areas of industry finding $10s to $100s of billions of value in LLMs. There's no lint or compiler that can check for correctly constructed contracts. So LLMs, which should be useful to law firms, incur a lot more manual checking of their work than coding agents.
Less formal document production in other industries is likely to have less structure. That might not matter in some settings but I'm having trouble thinking of an example off the top of my head.
There are definitely linters and this exists https://catala-lang.org/
Translation between languages.
That value dwarfs all programming value that can be had. Economically, culturally, scientifically, spiritually.
This is in the article.
It doesn't mean hosted frontier models wont exist, they'll just be rare. It's no different than any other commodity market, for example most cars are cheap commodity models, with rare individuals buying expensive luxury cars and businesses buying expensive trucks and specialized equipment.
I don't want Shakespeare, I want Bob the builder.
Half of my work is telling claude how to behave. I'm pretty certain they have enough _data_ to realize people do the same thing time and time again.
Check this comment of mine for a better explanation of this: https://news.ycombinator.com/item?id=49413353
But people are not as alike as you think. I doubt I share your unique preferences.
That said, I don't spend much time telling it how to behave. Are you sure you're not fighting the default system prompt?

[...] the "naturalness" with which we use our native tongues boils down to the ease with which we can use them for making statements the nonsense of which is not obvious. It may be illuminating to try to imagine what would have happened if, right from the start our native tongue would have been the only vehicle for the input into and the output from our information processing equipment. My considered guess is that history would, in a sense, have repeated itself, and that computer science would consist mainly of the indeed black art how to bootstrap from there to a sufficiently well-defined formal system.

Either way, a model used to solve the top 10% of problems that people use AI to solve for, being used 10% of the time … seems like it’s in a decent place.
I find Fable indispensable, and measurably better than alternative models, for complex feature development in an existing codebase. It’s the closest thing I’ve seen to nearly one-shotting features. Even still, I only use it for the hardest features and Opus 5 does a good enough job on the rest.
Once the government stepped in, their 5th generation was effectively killed. They either had to lock it up (Mythos), neuter it (Fable), or leave people with the perception they were overpaying for a weaker model (Opus 5).
Hopefully Anthropic has learned to anticipate this risk and has a plan for rollout of their next model that plans for capricious ad-hoc regulation.
I mean, who says "screw you" to requests to get 35+ year old vintage computers working? Claude, that is who. Its guard rails are so stupid. I hear people trying to do simple mailing list management hit it too.
I am just about done with them.
I can hand hold opus but I would rather just ask fable to do it and give me the result that I review and works. Opus will waste tokens and still require me to help nudge it in the right directions.
I think the next gen models from china will put us in a spot that the cost can plummet and I won’t need the Sota from anthropic
Also, Sol doesn't refuse constantly and speaks like an engineer rather than a deranged academic.
Opus 5 is legitimately terrible and can't or won't follow instructions. It is of negative utility and does more harm than good to my codebase.
Most of the benchmarks have exceeded their usefulness. Opus 5 beats fable 5 on many of them. Anyone who has used both models will notice immediately that this doesn't translate to the real world. Opus 5 is nothing short of a regression from Opus 4.8. Fable is genuinely a great model so long as you don't trigger a guard rail and it downgrades.
Sol in my experience isn't significantly different than fable ignoring that Sol burns usage 10x faster but the end result is hard to differentiate.
GLM 5.3 is a hair behind these two.
An anecdote but not an original one from the people I talk to.
But Fable security false positives and pricing just make it not worth compared to Sol IMO.
Fable is not used because it has extra retention requirement that corps can't sign off so it stays disabled for everybody in many cases.
It's also not winning on day to day work against Opus 5, which is simply available as there are no extra retention requirements and no extra paper work to do with legal.
Devs also don't like that Fable refuses to work on half of their prompts.
Then comes better pricing and on-par capabilities from competition.
But a while ago, I had access to a Fable harness that just never gives up. And that verifies itself. It burned $100 in API tokens in 15 minutes ... but it succeeded for all the prompts where Fable + Claude had failed.
And I believe that's a real issue for Anthropic. Fable+Claude is not too expensive thanks to the subscription, but Claude severely nerfs Fable. To save money, I guess. Fable API + Custom Harness is a different class, it's so much better. But API tokens are so expensive, you're cheaper off hiring a freelancer.
I would compare it to a extremely high end $15k PC, or an expensive pro-grade video camera, or a freight train, or a …
I would say at least 95% of the global population will not encounter a situation once in their life where it would be actually useful/warranted.
It’s more reliable and makes less dumb errors than Opus.
It still messes up, of course. But for my working style, I definitely prefer it.
That said, Opus 5 is broken. Use 4.8 or another vendor for the build agent.
Yes but those issues will be much less severe with Fable-written plans than those written by lesser models. I know this because my workflows at both my regular job and my startup involve multi-step agent reviews via codified adversarial review skills. Fable as a reviewer will frequently find blocker-level issues with plans written by GPT 5.6 Sol, and sometimes with Opus 5. The opposite almost never happens. In fact I cannot remember the last time it happened.
Cheaper, more powerful AI will continue to expand the bubble. Projects will get more ambitious. Everyone will build out their own custom little software. Code diversity expands and requires even more AI.
They are already good enough at what they mechanically are.
You have to use the right harness, right verifiers (automatic where possible, human where not), etc much much more specific than a generic one like claude code or codex, and it will also be able to work within constraints and be the "proposer" of an imaginary optimisation problem and an excellent one at that. But you have to frame the task at hand in that manner or maybe even reorganise the task you do itself so it is more amenable to being framed that way. If you use it this way, it is _already_ massively economically useful. But it will take many years for it to actually be usable in that way, since you need DC capacity to come up first which is few years away and also well, massive organisations that have to integrate these will usually take many years to do so.
It is also useful albeit less so in cases like general SWE, where you still need a human in a loop for non-verifiable requirements, and also in other general usecases where information retrieval is too intractable and you need to carefully use LLMs as a component of the overall system.
I am not saying Fable or whatever the biggest models are are useless - they will certainly be useful for tasks at the frontier of the day - which is today complex exploits and open math problems, and well, tomorrow it could be something in biotech. But this is not what the entire bet is on at all - just automating day to day drudge at the tens of thousands of massive companies and governments we all know and love is more than enough. With the right training data (which _also_ is a bottleneck and takes time) you could even automate certain processes entirely. Sure, if we get a crazy medical innovation and end up saving trillions in healthcare great, but that's just a bonus.
None of this is to say that I think there is zero sketchy financial engineering going on
And you can have extremely simple work that you nevertheless have to do as a professional. For example, drafting a routine customer email, summarizing a meeting, formatting a report, filling in standard documentation, or making a trivial code change.
So I don't think the $15k workstation / professional camera analogy really holds. Those are specialized tools whose capabilities are mostly useful within a fairly narrow domain. A general-purpose AI can be useful across thousands of completely unrelated tasks, including one-off problems encountered by ordinary people.
What if:
- Opus 4.6 was the last Opus generation that got a lot of use by Anthropic's own employees
- After that they primarily used Mythos internally
- 4.7, 4.8 and 5 were RLAIFd by Mythos "teachers"
- Hence why 4.6 is the last Opus gen who doesn't report back like a robot wanting to cover every potential hole another AI system would've spotted and criticized
- Hence why coding style in Opus 5 also gets criticized, not only behavior in CC
[1] https://github.com/zachahn/vomit
I switched from Opus 4.7/4.8 to test Kimi K3 a few weeks back and the test hasn't finished; it's my daily driver now.
Given their general behavior and preference toward social engineering to scare the shit out of normal people...this seems fitting.
1. They acted as if they were so far ahead capability wise that they could stop listening to their users.
That is basically it. It is an extremely common belief that Opus 5 acts like a condescending wannabe-thought-leader, yet Anthropic's response to this is largely been "You're using it wrong. Try deleting all your config files".
They released a "concise" output format, but pretty much swept it under the rug, despite it being one of the loudest complaints about their models. It also, generally, does not work as described.
Not only did Opus 5 get much more difficult to work with, but it got, from a customer view, significantly slower. The token rate might be the same, but if every interaction takes 50% more tokens, it's 50% slower.
All this time OpenAI has released a slew of new models, lowered the price on them (which, bluntly, 80% of user count don't actually care about since they're on subscriptions), increased subscription capacity, and increased response speed.
It's not about cost. It's about Anthropic being the frontier-lab version of the marathon runner who decides to celebrate to early, and then loses the race.
This wouldn't be so bad if it didn't make mistakes periodically, especially when it's about to tap out. I get the sense that if I upgraded to the $200 subscription it would get me a lot more usage, but it would still run into these issues anytime I sat down to work for a few hours.
I'm just using medium effort, so it's not like I'm on high all the time.
This is the first time I've felt, and I use the word *felt* since I don't have a suite of benchmarks or any sort of material approach towards comparing models, that Opus has declined in quality compared to before. Primarily I think its powers of deduction and understanding, even on xhigh, have become much worse. Before, being vague and providing a simple prompt would be enough, it could deduce and expand the details it needed, plus ask you clarifying questions, now this is no longer the case. A concrete, personal example, for a personal project, I've asked it to setup ssl over local IP. I didn't go into too much detail in the prompt as there are many approaches it could take and I didn't care too much to choose. It did horrible. The first thing it did was say the best lightweight approach is to add a reverse proxy. I'm like ok, makes sense. Then after asking it to proceed, it went and added a bunch of config to my golang service and didn't even setup a reverse proxy even when it said that is the way to go. It even said it didn't set it up lol. Then after I told it to do so it failed building the config in a way it was asked of it (support LAN IP and tailscale IP). Etc etc...
When Fable came out it was huge, the benchmarks told the story, and the story mostly matched the experience. It felt, again, intentionally saying felt, like it was miles ahead. Now benchmarks say that there are many models that are close, but in actual use Fable still *feels* much better. I think benchmaxxing the new open weights models is ruining the value of benchmarks, if they ever had any. When you actually put them to the test you see 500k tokens of reasoning with "Actually..." and "Wait..." in every third paragraph of their reasoning trace.
The price for Fable is definitely too much for any personal use now that it's no longer included in the subscription, and GLM 5.2, Deepseek Flash and Qwen 3.8 served locally or via cloud provide a lot, requiring a bit more babysitting though. Considering the price of Fable, my 5k USD Epyc server would pay itself off in less than a year if I used Fable or Opus in the same manner so at least for me the decision seems easy. And considering the point I'm poorly trying to make, that Opus doesn't feel like frontier anymore, this is probably the last month of my Claude subscription.
I've wondered if this is part of why we don't see the reasoning traces for Anthropic's models before -- Open models might just be accurately surfacing how the sausage is made.
Anthropic in particular is much more compute-constrained than OpenAI and SpaceXAI and has relied on partnerships to provide inference. This reality factors into their pricing and usage limits (they started 'adjusting' the 5-hour limits during peak hours, and it certainly wasn't an upward adjustment). Accordingly, this is presumably what Anthropic wants, given they develop and release the lower-end models, suggest users use them in various nudges within their product, position the bigger/more expensive models as "For the most complex tasks" in their UIs, and so on.
I think the problem (for Ant/OAI) is that there is no sensible lockin or moat. LLMs are essentially interchangeable and stuff like a harness doesn't offer enough value on its own for someone to be locked into using one of them.
Now with the onslaught of the Chinese models that offer almost the same quality for much less money they have a very serious problem on how to proceed. Investors now might be looking through rose tinted glasses but their patience has its limits.
Enterprise is a whole different ballgame IMO with countless technical, compliance, and employee adoption considerations that add friction to switching. It's also where both Anthropic and (as of last week) OpenAI get the bulk of their revenue, and, incidentally, the venue where US Government regulations on Chinese models would have the most impact.
Nobody has complained and seems like for every use case we have Opus is more than powerful enough, especially with Opus 5
I find it funny how OpenAI got caught lacking for a very brief window, but it turned out to be a very critical turning point.
Like a guy that that's at the top of their game the entire year, and the one day they have the flu, the CEO does a surprise performance review.
Sure there are Microslop and Oracle db users but most of the world we live in is Postgres and Linux. That's why I think most companies will run llm's like that.
> good at its job just use it instead of re-inventing the wheel
Exactly why is everyone reinventing a harness every month. There will be Microslop / Oracle harnesses and there will be 1 or 2 open source ones that win.
if people dont see why they need a model this smart, they probably arent using ai enough
I am not doing awfully complex tasks though. I imagine a lot of other people are in a similar boat, either switching from Claude to ChatGPT or even just min-maxing DeepSeek V4 Flash 0731 or similar.
Anthropic is the fastest-growing software company in history. They have no issues "attracting users"

No shit we're all paying 清冲 Flash to do the grunt work. Turns out though, paying 清冲 Flash a few more cents does exactly what Ivy Wasp Pro Mythical does. Crazy how that works.
Most of the people pushing this are just hoping that they can cash out before the hype pops and financial gravity crashes the party. Sam Altman recently claiming that the singularity is here is so stupid on its face he should just be treated as what he is, a huckster.
None of this stuff ever made any sense on what it was being sold initially. It was always insulting that the media and business leaders tried to argue that the tech could replace entire call centers or vast swaths of entire industries.
People keep arguing, but it will or it has based on extrapolating certain, reasonable use cases. Klarna has shut up about replacing call centers with bots because Markov chains with memory only can do so much.
I’m happy with Claude. If they become (bigger) jerks, I’ll switch to something else. I don’t ha e the energy to praise Anthropic today and I won’t have the energy to demonize them tomorrow. The emotional investment people have for/against these companies feels like celebrating or being offended by the weather.
TBH I don't think any of that is unique to the IT industry's relationship with the Valley. Other technology-driven industries have a similar worship-ish relationship with a few rarified businesses. But the culture of the IPO exit accelerates all the most short-term motivations to do anything.
I can literally open a new chat with just "Hello" and it gets bumped.
Claude keeps track of memory if you've turned that on so all conversations are somehow tracked over time Claude randomly will mention that I'm a developer while I'm asking unrelated questions and say oh because you're a developer you might like this or because of my background and infrastructure you might find this interesting and I always get creeped out by it.
They have the concept of incognito chats, but I can see those being worse without context from other conversations happening.
Regardless, the number of innocent biochemists who have been hamstrung by Fable is essentially zero (but somehow they have all shown up on Hacker News to decry Fable), and the number of non-innocent would-be-biochemists who would love to have unrestricted Fable help them with their non-innocent biochemical research is absolutely greater than zero.
In my view, from the testing I did since Thursday, it's better than Fable. I had just finished a rather large task that Fable completed, including a /review and an /ultrareview.
Ox Alpha found bugs that Fable and Opus missed, and it continued to build things like a pro.
It does have issues with availability - but it's on a free promo right now. That also means that I don't know how much it would have cost if I had to pay API prices for it, which might not be cheaper than the subsidized small company / consumer usage, but for large companies paying API prices for either offering, the difference will be considerable.

So yeah, I and I guess others, are quite active in whatever little way we have available, to up vote new models and share stories.
