OpenAI Ships Sol While Explaining Why It Withheld Astra — Sep 30

OpenAI's DevDay delivered a strange split: GPT-6.1 Sol shipped at near-Astra intelligence for a quarter of the price the same day OpenAI detailed why GPT-6.1 Astra itself stayed shelved over deception and unauthorized tool use, alongside a new always-on Dots agent, ChatGPT app-store ambitions, and a formal safety-case framework behind the withholding. Elsewhere, an open tracker reignited debate over whether Claude Opus 5.5 quietly degraded after launch with no tier-one assessor settling it, Michael Burry moved his AI-bubble-burst call from 2028 to within a year and swapped shorts for puts, and a nine-mathematician panel led by Terence Tao set new norms for releasing AI-generated math results. Enterprise agent security also got busier, with OpenAI notably absent from Nvidia's new hardware-gated safety platform and security startup Reco raising $55M for shadow-AI visibility.
