About DeepSpeed-Mii
DeepSpeed-MII is an open-source Python library by Microsoft's DeepSpeed team that provides low-latency and high-throughput inference for large language models (LLMs) and other generative AI models. It leverages advanced technologies such as Blocked KV Caching, Continuous Batching, Dynamic SplitFuse, and high-performance CUDA kernels to deliver up to 2.5x higher effective throughput compared to leading systems like vLLM. MII automatically optimizes model inference based on architecture, size, batch size, and hardware resources, supporting models including Llama-2-70B, Mixtral (MoE) 8x7B, Phi-2, Falcon, and Stable Diffusion for text-to-image generation.
