Originally, I saw it on Gemini docs below. Since all the use case of the new reasoning model was specific the v1alpha, I thought it's necessary.

https://ai.google.dev/gemini-api/docs/thinking#send-basic

To use the new thought parameter, you need to use the v1alpha version of the Gemini API.

but seems like "gemini-2.0-flash-thinking-exp-01-21" is also available in v1beta. I think it's probably an feature update between v1beta and v1alpha, instead of a cut off.

I think it shouldn't be marked as a bug fix. And having discussion of the API version implement.

It might be best to postpone the change until LobeChat officially supports reasoning/thinking models.

I have tried with google sdk, it doesn't support CoT by now: google-gemini/generative-ai-js#328. So need to wait for their update.
