system cards

Zvi Mowshowitz criticizing Google DeepMind for releasing Gemini 3 Deep Think — a model with dramatic capability jumps across ARC-AGI-2, IMO, IPhO, IChO, and Codeforces — without publishing a system card or safety explanation, on the grounds that it was merely a "runtime improvement." Directly relevant to Nathan's AI governance/safety interests: a documented case of a lab treating major capability gains as exempt from safety disclosure norms. Follow-up to the previous tweet — Google walked back its earlier claim that no safety evals were needed for Gemini 3 Deep Think, saying evals were in fact run and would be shared, blaming a "communication issue." Part of Nathan's tracked thread on lab transparency practices around capability jumps.
