OpenAI’s GPT-6 Astra large language model reached general paid-user and API availability in early September 2026 after an August pause triggered by its own Preparedness Framework over potential critical cybersecurity capabilities. The model remains listed in the company’s API catalog and powers active ChatGPT products and agent tools with no announced deprecation or broad access restrictions as of mid-October. Traders assign low implied probability to near-term removal because the release cleared internal safety reviews and enterprise gating, though continued monitoring of agentic behavior, chain-of-thought opacity, and any new regulatory scrutiny could still shift sentiment ahead of October or December resolution dates.
