Beginning this morning, Thoughts are not included in the streamed response anymore. when using: "generationConfig": { "thinkingConfig": { "includeThoughts": true } } Text parts are not reported anymore in the response, and only post-thought text is streamed. Expected: yesterday…

Hey everyone, Thanks for flagging. I am seeing the same thing (thought=None), not only with the generate_content_stream but with the generate_content also. One thing mentioned in this doc is that it’s not guaranteed but let me follow up with the internal team on this. Thanks.

same issue here. thanks for looking into it.

same issue here. I tried running 100 queries and not even once got the thoughts

Tried changing options, on v1beta, fishing for parameters… nothing. I don’t know how to get the CoT back, and I was reading it to get assurance about the quality of the output. It’s my fav model otherwise.

Hey Everyone, Moving forward, our team has made a decision to only show thoughts in Google AI Studio. Meaning, we no longer return thoughts via the Gemini API. Here is the updated doc to reflect that. Thanks.

Thank you for your feedback. Does the thinking happen in the background and would that change the reasoning in anyway? Is this permanent? Thank you

Are you planning to bring it back in the future? It was the main reason for me to start using the model. Thank you

Correct, the reasoning / thinking is still happening when you use the thinking model via the API, it is just not showing the thoughts in the response anymore. Yeah, I believe this will be the case moving forward. Thanks.
