Overview

PrivateGPT is an open-source API layer that enables developers to build private AI applications on local models. It provides a standardized API for messages, ingestion, tools, retrieval, citations, database access, tabular analysis, MCP, skills, and custom tools. PrivateGPT is designed to work with any OpenAI-compatible inference server, allowing developers to build AI applications without depending on cloud APIs. The API is production-tested and powers Zylon, an on-premise AI platform for enterprises. PrivateGPT includes features such as standard messages API, file and artifact ingestion, retrieval with citations and agentic RAG, built-in tools mirroring the Claude API, custom tools and MCP connectors, structured access to databases and CSVs, embeddings and orchestration. The API is compatible with the Claude API and supports model selection, messages, streaming, batch/async processing, token counting, knowledge, tools, data, agents, output, and optimization. PrivateGPT is API-first, providing a standardized local backend for building self-hosted AI applications. It is maintained by the team at Zylon and is available under the Apache-2.0 license.
