Lightning-AI/LitServe
A minimal Python framework for building custom AI inference servers with full control over logic, batching, and scaling.
LitServe helps AI developers build custom inference servers for their AI models or multi-model applications. You define the exact logic for how your models process incoming data and produce results, including custom batching, routing, and streaming. It takes your Python code with model definitions and deploys it as a scalable web service, perfect for AI engineers creating unique AI solutions.
3,812 stars. Used by 1 other package. Actively maintained with 6 commits in the last 30 days. Available on PyPI.
Use this if you are an AI engineer or MLOps specialist who needs full control over the inference logic for complex AI agents, RAG systems, or multi-model pipelines, rather than relying on off-the-shelf serving tools.
Not ideal if you simply need to deploy a single, standard large language model and prefer an out-of-the-box solution like vLLM or Ollama without custom logic.
