I posted a related issue/feature request and will link here so that the issue is a little clearer: [REQUEST] agent support for gemini-2.5-pro-preview-03-25 via API keys
I requested agent support for -preview since that currently doesn’t exist. It looks like we need both routing for -max to be able to go to -preview and for there to be agent support for -preview. Right now it seems like there is no full integration of -preview even though the model is nearly the same as -exp, which does have agent support. I’m hoping it’s just a config change on Cursor’s side.
