OpenAI Retires GPT-5.2 and Moves Everyone to GPT-5.5 and the GPT-5.6 leak
Summary
OpenAI has retired GPT-5.2 in ChatGPT and routed users to GPT-5.5 instead. The move affects existing conversations and can change output behavior, even when the model family looks similar on the surface. Developers who rely on OpenAI should pin model versions, rerun evaluations, and validate prompts and output parsers against GPT-5.5. The article also notes a leaked GPT-5.6 checkpoint, but treats it as unconfirmed and not something teams should plan around. For businesses, the immediate task is to verify production workflows and treat the current model swap as a real migration event.
