Summary of Changes

Hello @stzoozz, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves an issue where model recipe downloads were hardcoded to the default HuggingFace endpoint. By leveraging the HfApi client, the system now dynamically determines the endpoint, allowing users to specify a custom HuggingFace endpoint via the HF_ENDPOINT environment variable. This change enhances the adaptability of the system for environments requiring alternative or mirrored HuggingFace services, directly addressing issue #1967.

Highlights

• Custom HuggingFace Endpoint Support: This pull request introduces support for configuring a custom HuggingFace endpoint for model recipe downloads, enabling greater flexibility for users operating in different network environments or with mirrored services.
• Replaced Hardcoded URL: The previously hardcoded HUGGINGFACE_CO_URL_HOME constant has been replaced with a dynamic endpoint retrieved from HfApi().endpoint, which respects the HF_ENDPOINT environment variable.

Code Review

This pull request correctly addresses the issue of supporting custom Hugging Face endpoints by replacing the hardcoded URL with a dynamic endpoint from HfApi. The change is well-targeted and fixes the problem described. I have one suggestion to slightly improve the implementation by instantiating HfApi only once, which would make the code more efficient and clearer.

Thanks for the contribution! This looks good to me, but the gemini suggestion is slightly cleaner if you'd like to apply the suggestion
