[daimoniac]

What features would you like to see added?

Ability to specify a list of providers that the request is allowed to be routed to through openrouter.

More details

use case: use models only hosted by GDPR safe subcontractors, e.g. DeepSeek R1 / OpenAI o1 hosted within EU.

Openrouter provides API to do that: https://openrouter.ai/docs/features/provider-routing#example-specifying-providers-with-fallbacks-disabled

You can specify the list of models you want to use in the custom endpoint configuration.

Thanks @danny-avila , this is not about the models i want to use, but to specify the allowed providers for each model.

You can specify the list of models you want to use in the custom endpoint configuration.

Using this parameter allows you to choose the minimum quantization level of models, or prioritize either speed or cost, depending on your needs. Overall, it’s a very useful feature for integration with OpenRouter, as it gives you more flexibility to optimize for specific requirements and use cases.

Commenting to show interest in this capability.

Another use case is to specify provider Google Vertex for gemini-2.5-pro-exp-03-25:free since Vertex does not train on inputs while AI Studio does.

Along the same line as the above comments, OpenRouter gives the ability to ignore providers that use your chats for training: https://openrouter.ai/docs/features/provider-routing#requiring-providers-to-comply-with-data-policies .

Would the only way to incorporate this be to manually create a list of models and add them to the custom endpoint configuration in librechat.yml and every so often manually re-create it?
