@SBrandeis @julien-c @hanouticelina This PR has been ready for over a month. We're blocked on server-side provider enablement to access the Model Mapping API. Posted in discussions 28 days ago. Can you help move this forward or provide guidance? API is live and ready for validation.

Hey there!
Thank you for your interest in becoming an Inference Provider and for the excellent work you've put into this integration!
We really appreciate the effort.

However, we're currently in a consolidation phase focusing on growing usage of Inference Providers via new features and integrations rather than expanding to new partners. This means we've temporarily paused onboarding new providers while we work on these improvements.

We're not able to provide a specific timeline for when we'll resume new provider onboarding, but we'd love to revisit this integration in the future.

Thanks again for your contribution and understanding!
