+
+The [GitHub Models](https://github.com/marketplace/models) provider, `github`, allows running models through the GitHub Marketplace.
+This provider is useful for prototyping and subject to [rate limits](https://docs.github.com/en/github-models/prototyping-with-ai-models#rate-limits)
+depending on your subscription.

+<li>
+
+Open the [GitHub Marketplace](https://github.com/marketplace/models) and find the model you want to use.
