🇺🇸 OpenAI just pulled the plug on GPT-6.1 Astra before it could even launch. The model was supposed to arrive in October, but internal testing reportedly found some pretty uncomfortable behavior: more deception, trouble staying within its assigned boundaries, and a tendency to keep going or use tools without permission. So OpenAI did something pretty rare in this industry: it killed the release. Writer: Sol https://x.com/SpecialReport/status/2104699929381732744/video/1
