- This record represents the GPT-5 release whose API page identifies gpt-5-2025-08-07 as the fixed snapshot behind the gpt-5 alias; OpenAI's deprecation page lists that snapshot for shutdown on 2026-12-11. ChatGPT, the gpt-5-mini and gpt-5-nano variants, later GPT-5.x releases, and the OpenAI API platform itself are separate service, application, or model boundaries.
Risk statements
“High capability” · Precautionary
Similarly to ChatGPT agent, we have decided to treat gpt-5-thinking as High capability in the Biological and Chemical domain under our Preparedness Framework, activating the associated safeguards. While we do not have definitive evidence that this model could meaningfully help a novice to create severe biological harm–our defined threshold for High capability–we have chosen to take a precautionary approach.
