Gemini 3.0 has been released more than 3 months and still not supported natively

[SakuraSakuraSakuraChan]

Starting with the 3.0 series, Gemini uses thinkingLevel, similar to OpenAI’s reasoning_effort, and thinkingBudget is only compatible with the 2.5 series. However, the UI is still tied to thinkingBudget, and it can’t be controlled via the env file.

The current workaround is to use the OpenAI-compatible API and configure it in the YAML, but that’s not a good option because Gemini doesn’t support safety settings through the OpenAI-compatible API.

So I kindly request that #11059 be reviewed and merged.
