Block’s Daybreak Security, Third Moment’s Agents, and Gemini 4 Argon
Block and OpenAI are using Daybreak for security investigations and proposed patches; Third Moment Research describes long-running Codex agents, while Simon Willison adds Google’s Gemini 4 Argon to llm-gemini. Also covered: the PerSo persuasion benchmark, Anthropic’s Opaque Systems agreement, British AI-regulation testimony, and Colossal Biosciences’ de-extinction platform. Block describes AI-assisted security triage, investigation, and patch proposals with human review. Third Moment Research details sustained agent investigations and a faster quantitative-finance backtest. Simon Willison adds Gemini 4 Argon support and examines API and benchmark-run costs. PerSo tests perspective-reading and persuasive responses using ChangeMyView dialogues. Anthropic agrees to license Opaque Systems technology and hire some engineers. OpenAI and Anthropic call for British AI legislation; Google DeepMind and Meta decline to back new laws. Colossal Biosciences announces an AI platform, with a Peter Diamandis fund for startups using it.
