Hey, unfortunately we take heed from Google on which endpoints and model versions to use under the hood, but as far as we know, the rate limits are not too dissimilar, so the experience with the other model would be the same.
Besdies overriding the OpenAI endpoint URL, I unfortunately think there may not be any changes here.
@superjavi This is a Google error due to high use of your API key, and there is no way to bypass it unfortunately, just got to wait until you are no longer rate limited. You can learn more here:
