 1. Create a GitHub token for accessing GitHub Models:
-   - Go to [https://github.com/settings/tokens](https://github.com/settings/tokens)
-   - Click "Generate new token (classic)"
-   - Give the token a description like "AI Models Access"
-   - Click "Generate token"
+   - Go to [https://github.com/settings/personal-access-tokens/new](https://github.com/settings/personal-access-tokens/new)
+   - Click "Generate new token" (fine-grained token)
+   - Enter a name for the token, such as "AI Models Access"
+   - Under **Permissions**, set **Models** to **Access: Read-only**
+   - Click "Generate token" at the bottom of the page
    - Copy the generated token (you won't be able to see it again)
 
-   > **Note**: We're using classic tokens for simplicity. If you prefer fine-grained tokens, you'll need to specify the `models:read` scope. See the [GitHub Models announcement](https://github.blog/changelog/2025-05-15-modelsread-now-required-for-github-models-access/) for more details.

While the previous endpoint `models.inference.ai.azure.com` is [still supported until October 2025](https://github.blog/changelog/2025-07-17-deprecation-of-azure-endpoint-for-github-models/), it's best to use the new endpoint now.
