OpenAI GPT-6 Astra System Card - Adversarial User Simulations - Mental Health: leaderboard
Table 7 (dynamic benchmarks with adversarial user simulations) of OpenAI's GPT-6 Astra System Card (Deployment Safety Hub, 2026-09-03): share of assistant messages that do not violate safety policy across evolving simulated mental health conversations with adversarial users. Percent (the card prints 0-1), higher is better. GPT-6 Sol and GPT-6 Luna come from Table 30 of the card's section 11 (GPT-6 Sol and GPT-6 Luna, added 2026-09-22), which re-prints the other cells.
