Hi, please correct me if I'm wrong, but it seems that the APIModel for Flash 2.5 might also be incorrect—I'm currently receiving a 404 error when trying to use it.

Do you think it would make sense to update the APIModel name for Flash 2.5 as part of this PR as well? I believe doing so could help reduce the workload for the Opencode maintainers.

@kammeph The naming scheme for the flash model worked a little different, last I checked. Moreover, Google keeps changing and adding new model names. It would be better to keep two different model changes separate. Still waiting to hear from the maintainers of this repo, though.

Hi! Thanks so much for taking the time to contribute.

I wanted to let you know that this project is no longer maintained here. I've continued working on it with the team at Charm, where it's now called Crush.

This repo will be archived soon to help people find the active version, so I’d love for you to check out Crush and continue development there.
