Which AI Model Does Firebase Studio Use by Default?

Hi everyone,

So, I have a bunch of doubts about Firebase Studio.

Default Model: Is the built-in model Gemini 2.5 Flash, Gemini 2.5 Pro exp 03-25, or Gemini 2.5 Pro preview 05-06?
Mode-Specific Models: Do the prototyping mode and code editor mode utilize different models?
Rate Limits: What are the rate limits associated with these models?
Future Plans: Are there any announced plans regarding model upgrades or changes in Firebase Studio about these models?

I’ve searched but haven’t found clear information on these points. Any insights or official documentation references would be greatly appreciated!

For prototyping, we are on the latest Gemini 2.5 Pro model. For our chat in our coding workspace, we are using Gemini 2.5 Flash. We may dynamically change the model for certain activities depending on which one we feel is best suited to handle a particular response.

For example, AI activities like code completion use a different Gemini model from the other two.
