Pros

+Exceptional serving throughput with PagedAttention memory optimization and continuous batching for production-scale LLM deployment
+Comprehensive hardware support across NVIDIA, AMD, Intel platforms and specialized accelerators with flexible parallelism options
+Seamless Hugging Face integration with OpenAI-compatible API server for easy model deployment and switching

Cons

-Requires significant GPU memory for optimal performance, limiting accessibility for resource-constrained environments
-Complex setup and configuration for distributed inference across multiple GPUs or nodes
-Primary focus on inference means limited support for training or fine-tuning workflows

Use Cases

•Production API serving for applications requiring high-throughput LLM inference with multiple concurrent users
•Research and experimentation with open-source LLMs requiring efficient model switching and testing
•Enterprise deployment of private LLM services with OpenAI-compatible interfaces for existing applications
