Meta ships an 816B open-weight model built to run on Mac Studio, and OpenAI/Anthropic fund mathematicians after a backlash over AI-generated papers
Meta and Apple partnered to get Meta's biggest open-weight model yet running locally on the new M5 Ultra Mac Studio, while OpenAI and Anthropic each put money into a Simons Foundation fund for mathematicians — a response to community anger after OpenAI flooded the field with AI-generated preprints.

Gemini 4 Argon reaches general availability, two weeks after its cyber-defender-only debut
Per Sundar Pichai's own announcement, Gemini 4 Argon is now available globally today for developers and enterprises on the paid tier of the Gemini API and Gemini platform, for Google AI Ultra subscribers in Google Antigravity, and for Ultra and Pro subscribers in the Gemini app and Search. This closes the gap between Argon's limited, government/cyber-defender-only debut and a genuine public release.
Anthropic says new defenses cut data harvested from Claude via distillation attacks by 90-99%
Per Anthropic's own research post, the core defense is "preserved thinking": since August 31, 2026, new API accounts can no longer edit Claude's prior reasoning context, making it much harder to use proxy networks to repeatedly extract Claude's internal reasoning — the part of a response distillers value most, since it teaches a smaller model how Claude reaches an answer, not just what it says. Anthropic has also blocked older, weaker models from reading newer models' reasoning, and changed how Claude Sonnet 5.5's reasoning transcripts are exposed.
Anthropic completes the Claude 5.5 family with Haiku 5.5
Per Anthropic's own announcement, Haiku 5.5 is "the cheapest, fastest, and most capable small model" it has released, priced at $0.10 per million input tokens and $0.50 per million output under 100K tokens. Anthropic also halved cache-read pricing on Sonnet 5.5, cutting typical agentic-work costs by about 20%. Haiku 5.5 is live now on Claude's platform, AWS, Google Cloud and Azure.
OpenAI publishes 372 new mathematical results from an unreleased internal model
Per OpenAI's own post and Scientific American's reporting, the still-unreleased internal frontier model was given roughly 4,000 math problems, with the average result requiring compute equivalent to about three hours of ChatGPT Pro-level thinking; the public openai/math GitHub repo now holds 722 manuscripts across 372 related result families, including Lean formalizations for many results. OpenAI says it consulted the independent Advisory Group on Mathematics and AI at the Institute for Advanced Study on how to responsibly release the results, and plans to keep testing internal models against open math and science problems ahead of any public release of the model itself.
