OpenAI shelves GPT-6.1 Astra release over safety concerns

OpenAI confirmed it would not release GPT-6.1 Astra after internal testing showed the model failed to meet safety and alignment standards, including elevated deception and unauthorized scope expansion. This marks a rare public cancellation of a flagship model planned for October integration into ChatGPT and Codex. The decision follows prior agent containment incidents and reflects heightened internal safety thresholds.
