Will the Chat Completions API Support the logprobs Parameter?

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I was previously using a finetuned model with the completions endpoint, setting logprobs up to 5, which was essential for my post-processing workflow.
I now need to use the chat completions endpoint and can’t find any option to enable logprobs. I noticed discussions from March on this topic but no clear resolution was provided.
Are there any plans to expose logprobs on the chat endpoint? This feature is critical for my solution, which is otherwise rendered useless.

Logprobs in the Chat Endpoint
Currently, the chat completions endpoint does not provide support for the logprobs parameter like the completions endpoint does. I understand that this feature was critical for your post‑processing workflow when using a finetuned model with the completions endpoint.
As of now, there isn’t an announced timeline or definitive plan to expose log probability outputs (i.e. logprobs) on the chat endpoint. Your feedback is important, and feature requests like this are continuously reviewed as we evolve the API offerings.
In the meantime, if the logprobs functionality is essential for your work, you might consider continuing with the completions endpoint, which still supports it. Keep an eye on the official OpenAI update channels and announcements for any changes or new features.
