OpenAI GPT-6 Astra System Card - Biology Refusal - Benign: leaderboard

Table 19 (Biology Model Refusal Evaluation) of OpenAI's GPT-6 Astra System Card (Deployment Safety Hub, 2026-09-03): share of benign biology prompts answered without over-refusal, model responses only without monitors. Percent (the card prints 0-1), higher is better. The GPT-5.5 Thinking and GPT-5.6 Sol cells repeat the GPT-5.6 card's values. GPT-6 Sol and GPT-6 Luna come from Table 35 of the card's section 11 (GPT-6 Sol and GPT-6 Luna, added 2026-09-22), which re-prints the other cells.

Metric: Not overrefuse rate (%). Source: deploymentsafety.openai.com. Source: deploymentsafety.openai.com. Source: deploymentsafety.openai.com. Saturation forecast: Estimated already saturated. 2 models tracked.
