You define a LitAPI subclass with setup() and predict() methods, then wrap it in a LitServer to handle concurrency, batching, streaming, and deployment. It's built on FastAPI but optimized for AI workloads\u2014you control how models are loaded, how requests are batched, and how outputs are routed, while LitServe manages performance, scaling, and infrastructure concerns.\n\nThe framework supports agents, RAG systems, multi-model pipelines, and any PyTorch-based inference workload. You can run it locally, self-host anywhere, or deploy to Lightning Cloud with one command. It includes features like automatic GPU scaling, request batching, streaming responses, and device management, making it suitable for teams that need flexibility beyond single-model serving tools.","worth_installing":"Yes, if you need to build a custom inference server with full control over batching, routing, and model orchestration. The low install friction, active maintenance, permissive license, and no security vulnerabilities make it a solid choice. Install with caution only if you require a pre-built, single-model serving tool (like vLLM for LLMs alone)\u2014LitServe is a framework for building, not a ready-made solution."},"id":"litserve","links":{"html":"https://skillfed.io/packages/litserve","md":"https://skillfed.io/packages/litserve.md","pypi":"https://pypi.org/project/litserve/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2025-12-23","license_spdx":null,"license_treatment":"permissive","name":"litserve","python_support":"supports_current","summary":"Lightweight AI server."},"popularity":{"monthly_downloads":94014,"position":13349,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.2.17"}
