About mistral.rs

mistral.rs runs language and multimodal models on your own hardware, with a command-line tool whose serve command exposes OpenAI-compatible and Anthropic-compatible endpoints. It loads local GGUF files or published quantised artifacts, and supports paged attention, prefix caching, in-situ quantisation, LoRA and tool calling.

It also has an agentic runtime with web search, local Python and shell execution, and Rust and Python SDKs for embedding. It suits developers and enthusiasts who want a fast local inference server on CUDA or Apple Metal hardware.

Strengths

  • OpenAI and Anthropic compatible API server
  • Text, image, video and audio input for supported models
  • Quantisation and GGUF loading built in
  • Very active development

Limitations

  • Command-line setup aimed at technical users
  • Performance depends on GPU hardware and backend
