1-) Gemini hit #1 on the U.S. App Store off the viral “Nano Banana” editor (10M+ new users, 200M+ edits).
2-) xAI shipped Grok 4 Fast (beta) — ~10× quicker replies via an “early access” toggle, trading depth for speed.
3-) ChatGPT (GPT‑5) rolled out improved reasoning/guardrails — far fewer naive “gotcha” prompts land now.
4-) Claude added auto‑memory (opt‑in) and weekly usage caps; Max ≠ unlimited Opus; user feedback is mixed.
5-) Safety/ops: cross‑chat memory has sparked “delusional” cases; even big labs get hit (e.g., Anthropic’s X hack).
Takeaway: virality + speed tiers now drive adoption more than benchmarks; the app‑store wars are real, and AI is shifting from novelty to consumer infrastructure.
