Hey @ashivadi,

Thank you so much for this PR and your contribution! We really appreciate the work you've put into this, and SAP GenAI Hub looks like a fantastic model provider integration.
While we'd love to include every great model provider, we've reached a point where we need to be selective about adding new providers directly to the core SDK to keep it maintainable and focused.

That said, we absolutely want to support your integration! We'd recommend one of these approaches:

• Option 1: Publish your model provider implementation as a standalone package on PyPI. This way, customers can easily install it and use it with our SDK. Here are some great examples of how this works: Clova Studio and Nvidia NIM.
• Option 2: Include it as a submodule in the official SAP Gen AI Hub SDK, which would give users direct access through an existing package similar to what they have for LangChain.

Either way, we'd be happy to feature you on our documentation page as a supported model provider, giving you visibility to our community. You can find more details here.

Would either of these approaches work for your use case? We're excited to see SAP GenAI Hub integrated with our ecosystem!
