 ### Multi-GPU Evaluation with Hugging Face `accelerate`
 
 To parallelize evaluation of HuggingFace models across multiple GPUs, we allow for two different types of multi-GPU evaluation.

 ### Commercial APIs
 
 Our library also supports the evaluation of models served via several commercial APIs, and hope to implement support for common performant local/self-hosted inference servers.
