Gemini 4 Argon: The Model and Safety Cards

Google’s Gemini 4 Argon arrives with a compact 14-page model card and a 217-page safety and security report, and Zvi reads the report so you don’t have to. He walks through the frontier safety thresholds for bio, cyber, manipulation and loss of control, the evidence on whether AI R&D is accelerating, chain of thought monitoring, sycophancy and hallucinations, and a model so aware of being evaluated that it addresses its evaluators directly, while asking where the card gives the right details and where it spins.
