Does Responses API support `stop` parameter or not?

Hi and welcome to the community! You are correct, the docs are outdated. For API-specific questions, I generally suggest using developers.openai.com. Unfortunately, those docs also look incomplete here because they state that o-series reasoning models do not support stop sequences, which is not the full picture with regards to the gpt-5 family of models. I will ping the team to review these findings.
