DescriptionvLLM's NVIDIA backend leverages CUDA kernels, FlashAttention-2, and PagedAttention to deliver state-of-the-art throughput for LLM inference on NVIDIA A100, H100, and H200 GPUs. The integration supports tensor and pipeline parallelism across multiple GPUs, FP8/FP16/BF16 quantization, and CUDA graph capture for minimal per-token latency.Native integration between LangChain and OpenAI's GPT models. Provides seamless access to chat completions, embeddings, and function calling through LangChain's unified interface. Supports streaming, tool use, and structured output via the langchain-openai package.
