  • Self-hosted LLM inference: Run quantized open-source models (Llama 3, Mistral, DeepSeek, Gemma, etc.) locally with a GPU or CPU, eliminating cloud API costs and latency.
  • OpenAI-compatible local API: Use Jan's local API server as a drop-in replacement for the OpenAI API in existing applications or scripts, enabling offline or air-gapped environments.
  • Multi-provider model switching: Build workflows that route queries to different model backends (local vs. remote) depending on task sensitivity or complexity.
  • Privacy-sensitive application development: Develop AI-powered tools for regulated industries (legal, medical, finance) by keeping all inference and data on-premises.
  • Model evaluation & testing: Rapidly test and compare responses across 100+ HuggingFace models and major commercial APIs from a unified interface.
  • Custom AI tooling: Extend Jan via its open-source codebase to build specialized assistants tailored to internal team workflows or products.
