I'd like to help with this issue, but I need some clarification to ensure I implement the right solution. Could you please provide more details on the following:

• "Gemini 3.1 Flash Lite" does not appear to be an existing Google model. Google's current Gemini lineup includes models like gemini-3.1-pro-preview, gemini-3-flash-preview, and gemini-2.5-flash-lite-preview-* variants. There is no publicly available "Gemini 3.1 Flash Lite" model at this time.
• Could you clarify which model you are referring to? For example:
  • Gemini 2.5 Flash Lite (gemini-2.5-flash-lite-preview-*) -- already supported via the Gemini provider
  • Gemini 3 Flash (gemini-3-flash-preview) -- already supported
  • A future model that has not yet been released?
• If you have a link to official Google documentation for the model you are requesting, that would help clarify the exact model ID and capabilities.

Please tag @roomote in your response with the answers, and I'll be happy to implement the fix once I have this information.

I've seen the comment with the documentation link for Gemini 3.1 Flash Lite. I'll explore adding this model to the supported Gemini models list and open a PR to share progress.

Opened PR #11889 with my attempt at adding gemini-3.1-flash-lite-preview to the Gemini and Vertex providers. Feedback welcome!
