PrivateGPT 1.0.0

This release merges two years of work from our private fork back into the open source repo.

The original PrivateGPT was a semantic search pipeline wrapped by a minimal API: ingest documents, embed chunks, retrieve by similarity, pass context to a local model. It proved the concept. PrivateGPT 1.0 is the full application backend that turns local models into production AI applications.

What's new

• A standard messages API
• Files and artifact ingestion
• Retrieval with citations, agentic RAG
• Built-in tools, mapping those offered by Claude API
• Custom tools support
• MCP connectors
• Structured access to databases and CSVs
• Web search and extraction
• Code execution
• Token counting, embeddings, and orchestration

Breaking changes

This is a major version. The original PrivateGPT API is not forward-compatible with 1.0. See the migration guide in the docs.

Architecture

PrivateGPT 1.0 does not run models itself. It connects to an external OpenAI-compatible inference server:

Your app / agent / workflow / UI
              |
        PrivateGPT API
              |
OpenAI-compatible inference server (Ollama, llama.cpp, vLLM, …)              

Note on Zylon

Zylon.ai, the commercial product built on top of PrivateGPT, has closed its private fork and will now develop against this open source repo. Iterations from the commercial side will flow back into the project publicly.
