Running a model locally is only the first step. To build useful AI applications you need a set of higher-level building blocks. PrivateGPT provides that layer as an open-source API following the Claude API model — so you can build private AI products without rebuilding the same backend primitives from scratch, and without depending on cloud APIs.

Production-tested: [PrivateGPT powers Zylon](#privategpt-vs-zylon), the on-premise AI platform providing Private AI to enterprises across the globe.


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

> PrivateGPT does **not** run models itself. It connects to any OpenAI-compatible inference server via `OPENAI_API_BASE`. If it implements `/v1/chat/completions` and `/v1/models`, it works.

PrivateGPT ships a built-in workbench UI for testing and demos, available at `/ui`. The API is the actual product.

## What PrivateGPT gives you

- Standard messages API (streaming, async, token counting)
- File and artifact ingestion
- Retrieval with citations and agentic RAG
- Built-in tools mirroring the Claude API (web search, web fetch, code execution)
- Custom tools and MCP connectors
- Structured access to databases and CSVs
- Embeddings and orchestration

## Quickstart

> For Docker, full installation options, and model configuration see the [full Quickstart guide](https://docs.privategpt.dev/getting-started/quickstart).

**Prerequisites:** You need a running OpenAI-compatible LLM server. [Ollama](https://docs.privategpt.dev/providers/ollama) is the easiest starting point.

**1. Install PrivateGPT**

```bash
# macOS
brew tap zylon-ai/tap
brew install private-gpt
```

```bash
# Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

uv tool install --python 3.11 \
  --find-links https://wheels.privategpt.dev/packages/ \
  "private-gpt[core]"
```

```powershell
# Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

uv tool install --python 3.11 `
  --find-links https://wheels.privategpt.dev/packages/ `
  "private-gpt[core]"
```

**2. Start your LLM server**

```bash
# Example with Ollama
ollama pull qwen3.5:35b         # LLM (~24 GB)
ollama pull mxbai-embed-large   # Embeddings (~670 MB)
ollama serve
```

**3. Run PrivateGPT**

```bash
# macOS / Linux
OPENAI_API_BASE=http://localhost:<llm-port>/v1 \
  OPENAI_EMBEDDING_API_BASE=http://localhost:<embedding-port>/v1 \
  private-gpt serve
```

```powershell
# Windows (PowerShell)
$env:OPENAI_API_BASE = "http://localhost:<llm-port>/v1"
$env:OPENAI_EMBEDDING_API_BASE = "http://localhost:<embedding-port>/v1"
private-gpt serve
```

**4. Open the UI**

Go to [http://localhost:8080/ui](http://localhost:8080/ui). The API is at `http://localhost:8080` and follows the [Anthropic API](https://docs.privategpt.dev/api-reference/api-reference) spec.

<img src="./fern/docs/assets/ui.png"/>

The UI is useful for:

- Sending messages.
- Selecting models from /v1/models.
- Uploading documents.
- Testing retrieval with citations.
- Enabling tools per chat.
- Configuring databases, MCP connectors, skills, and custom tools.
- Inspecting requests and responses through the API Debugger. 

This UI is a demonstrator, not the core product. Developers are expected to build their own applications on top of the API. That said, the UI is intentionally polished enough for demos, videos, internal pilots, and quick local usage.
