Today's Briefing: Google rolled out Gemini 4 Argon, but only handed it to "trusted cyber defenders" first; Anthropic and NIST aimed at Zhipu's GLM-5.3 offensive/defensive capabilities on the same day; after DevDay, OpenAI talked up a $30 billion raise while hitting pause on the GPT-6.1 release.
Editor's Note: These past couple of days, the overseas crowd has been spending more thought on the threshold. Whether a model can be built is one thing; whether they dare to open it up is another.
1. AI Large Models
1. Google releases Gemini 4 Argon, initially only open to "trusted cyber defenders"
- Summary: Google unveiled its next-gen frontier model Gemini 4 Argon, claiming it reaches frontier level in complex workflows, and for now it's only open to "trusted cyber defenders."
- Source: The Verge · 2026-10-01
- Editor's Take: Locking the strongest model in a safe first — Google is betting on the security narrative, at the cost of handing the first wave of buzz to someone else again.
2. Google employees aren't buying the new Gemini model
- Summary: Bloomberg says there's internal skepticism at Google about the new generation of Gemini models; employees' hesitation stands in stark contrast to the aggressive external marketing.
- Source: Bloomberg · 2026-10-01
