Today
GPT-5.6 Sol gets a 20%+ price cut. API and credit pricing falls to $4/$20 per million tokens — output down 33% — through at least November 21. Why: frontier quality per dollar just moved again. OpenAI
Nvidia’s AVO agent scores a perfect 100 on ARC-AGI-3. All 183 public-set levels cleared running Claude Opus 5 — which scores ~30% alone. Why: scaffolding is now the benchmark variable. NVIDIA
Mythos 5 enters Claude Security, with $35M for open-source fixes. Enterprise scans run on Anthropic’s frontier model; findings only, no direct access. Why: gated frontier defense becomes a product. Anthropic
OpenAI keeps its largest planned RL run on hold. Astra flagged for possible Critical cyber capability; near-term releases unaffected. Why: safety pacing is now release strategy. OpenAI
InstantDB team joins OpenAI. Instant Cloud runs until August 31, 2027; open-source stays self-hostable. Why: agents need state infrastructure. InstantDB
Brazil commits $444M to two AI supercomputers. 1.3B reais for a Huawei–iFlytek build in Rio; an Nvidia-tipped tender in Rio Grande do Norte targets a top-10 global machine by end-2027. Why: compute sovereignty goes multipolar. Reuters
Our take
Friday’s theme was infrastructure under new management: prices repriced, training paced, defense productized, and a database team absorbed — all moves that treat agents as production systems rather than demos.
