[omirosh]

Please consider changing framework for DeepSeek R1 to vLLM, it shows better performance over SGLang. Here is also documentation for running DeepSeek with vLLM.

@cquil11 , @functionstackx, I don't have the permission to assign a reviewer, so just tagging you both :). I know you guys are figuring out the load on the CI before moving forward with the review. Let me know what we can do to help.

@qcolombet yes, we are looking into it

@cquil11 is just trying to land an massive refactor PR first to reduce tech debt and then we can look into this one
