OpenAI announced GPT-6 Astra, claiming state-of-the-art results on FrontierMath Tier 4, ARC-AGI 3, and TerminalBench-4.0, plus major gains on Terminal-Bench Science 0.1 and HealthBench Pro, positioning it as an advance for scientific discovery. Commenter @iScienceLuvr notes the standout HealthBench Professional boost — and that OpenAI is nearly alone among frontier labs in featuring medical capabilities front-and-center in its announcement rather than burying them in system cards.
