---

## Installation

### Docker (recommended)
1. Install Docker: https://docs.docker.com/get-docker/
2. Create persistent directories:
   - Example (Linux/macOS):
     ```bash
     mkdir -p ${PWD}/har_and_cookies ${PWD}/generated_media
     sudo chown -R 1200:1201 ${PWD}/har_and_cookies ${PWD}/generated_media
     ```
3. Pull image:
   ```bash
   docker pull hlohaus789/g4f
   ```
4. Run container:
   ```bash
   docker run -p 8080:8080 -p 7900:7900 \
     --shm-size="2g" \
     -v ${PWD}/har_and_cookies:/app/har_and_cookies \
     -v ${PWD}/generated_media:/app/generated_media \
     hlohaus789/g4f:latest
   ```
Notes:
- Port 8080 serves GUI/API; 7900 can expose a VNC-like desktop for provider logins (optional).
- Increase --shm-size for heavier browser automation tasks.

### Slim Docker image (x64 & arm64)
```bash
mkdir -p ${PWD}/har_and_cookies ${PWD}/generated_media
chown -R 1000:1000 ${PWD}/har_and_cookies ${PWD}/generated_media

docker run \
  -p 1337:8080 -p 8080:8080 \
  -v ${PWD}/har_and_cookies:/app/har_and_cookies \
  -v ${PWD}/generated_media:/app/generated_media \
  hlohaus789/g4f:latest-slim
```
Notes:
- The slim image can update the g4f package on startup and installs additional dependencies as needed.
- In this example, the Interference API is mapped to 1337.

### Windows Guide (.exe)

👉 Check out the Windows launcher for GPT4Free:  
🔗 [https://github.com/gpt4free/g4f.exe](https://github.com/gpt4free/g4f.exe) 🚀  

1. Download the release artifact `g4f.exe.zip` from:
   https://github.com/xtekky/gpt4free/releases/latest
2. Unzip and run `g4f.exe`.
3. Open GUI at: http://localhost:8080/chat/
4. If Windows Firewall blocks access, allow the application.

### Python Installation (pip / from source / partial installs)

Prerequisites:
- Python 3.10+ (https://www.python.org/downloads/)
- Chrome/Chromium for some providers.

Install from PyPI (recommended):
```bash
pip install -U g4f[all]
```

Partial installs
- To install only specific functionality, use optional extras groups. See docs/requirements.md in the project docs.

Install from source:
```bash
git clone https://github.com/xtekky/gpt4free.git
cd gpt4free
pip install -r requirements.txt
pip install -e .
```

Notes:
- Some features require Chrome/Chromium or other tools; follow provider-specific docs.

---

## Running the app

### GUI (web client)
- Run via Python:
```python
from g4f.gui import run_gui
run_gui()
```
- Or via CLI:
```bash
python -m g4f.cli gui --port 8080 --debug
```
- Open: http://localhost:8080/chat/

### FastAPI / Interference API
- Start FastAPI server:
```bash
python -m g4f --port 8080 --debug
```
- If using slim docker mapping, Interference API may be available at `http://localhost:1337/v1`
- Swagger UI: `http://localhost:1337/docs`

### CLI
- Start GUI server:
```bash
python -m g4f.cli gui --port 8080 --debug
```

### MCP Server
GPT4Free now includes a Model Context Protocol (MCP) server that allows AI assistants like Claude to access web search, scraping, and image generation capabilities.

**Starting the MCP server (stdio mode):**
```bash
# Using g4f command
g4f mcp

# Or using Python module
python -m g4f.mcp
```

**Starting the MCP server (HTTP mode):**
```bash
# Start HTTP server on port 8765
g4f mcp --http --port 8765

# Custom host and port
g4f mcp --http --host 127.0.0.1 --port 3000
```

HTTP mode provides:
- `POST http://localhost:8765/mcp` - JSON-RPC endpoint
- `GET http://localhost:8765/health` - Health check

**Configuring with Claude Desktop:**

Add to your `claude_desktop_config.json`:
```json
{
  "mcpServers": {
    "gpt4free": {
      "command": "python",
      "args": ["-m", "g4f.mcp"]
    }
  }
}
```

**Available MCP Tools:**
- `web_search` - Search the web using DuckDuckGo
- `web_scrape` - Extract text content from web pages  
- `image_generation` - Generate images from text prompts

For detailed MCP documentation, see [g4f/mcp/README.md](g4f/mcp/README.md)

### Optional provider login (desktop within container)
- Accessible at:
  ```
  http://localhost:7900/?autoconnect=1&resize=scale&password=secret
  ```
- Useful for logging into web-based providers to obtain cookies/HAR files.

---

## Using the Python client

Install:
```bash
pip install -U g4f[all]
```

Synchronous text example:
```python
from g4f.client import Client

client = Client()
response = client.chat.completions.create(
    model="gpt-4o-mini",
    messages=[{"role": "user", "content": "Hello, how are you?"}],
    web_search=False
)
print(response.choices[0].message.content)
```
Expected:
```
Hello! How can I assist you today?
```

Image generation example:
```python
from g4f.client import Client

client = Client()
response = client.images.generate(
    model="flux",
    prompt="a white siamese cat",
    response_format="url"
)
print(f"Generated image URL: {response.data[0].url}")
```

Async client example:
```python
from g4f.client import AsyncClient
import asyncio

async def main():
    client = AsyncClient()
    response = await client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[{"role": "user", "content": "Explain quantum computing briefly"}],
    )
    print(response.choices[0].message.content)

asyncio.run(main())
```

Notes:
- See the full API reference for streaming, tool-calling patterns, and advanced options: https://g4f.dev/docs/client

---

## Using GPT4Free.js (browser JS client)
Use the official JS client in the browser—no backend required.

Example:
```html
<script type="module">
  import Client from 'https://g4f.dev/dist/js/client.js';

  const client = new Client();
  const result = await client.chat.completions.create({
      model: 'gpt-4.1',  // Or "gpt-4o", "deepseek-v3", etc.
      messages: [{ role: 'user', content: 'Explain quantum computing' }]
  });
  console.log(result.choices[0].message.content);
</script>
```

Notes:
- The JS client is distributed via the g4f.dev CDN for easy usage. Review CORS considerations and usage limits.

---

## Providers & models (overview)
- GPT4Free integrates many providers including (but not limited to) OpenAI-compatible endpoints, PerplexityLabs, Gemini, MetaAI, Pollinations (media), and local inference backends.
- Model availability and behavior depend on provider capabilities. See the providers doc for current, supported provider/model lists: https://g4f.dev/docs/providers-and-models

Provider requirements may include:
- API keys or tokens (for authenticated providers)
- Browser cookies / HAR files for providers scraped via browser automation
- Chrome/Chromium or headless browser tooling
- Local model binaries and runtime (for local inference)

---

## Local inference & media
- GPT4Free supports local inference backends. See [docs/local.md](https://github.com/gpt4free/g4f.dev/blob/main/docs/local.md) for supported runtimes and hardware guidance.
- Media generation (image, audio, video) is supported through providers (e.g., Pollinations). See [docs/media.md](https://github.com/gpt4free/g4f.dev/blob/main/docs/media.md) for formats, options, and sample usage.

---

## Configuration & customization
- Configure via environment variables, CLI flags, or config files. See [docs/config.md](https://github.com/gpt4free/g4f.dev/blob/main/docs/config.md).
- To reduce install size, use partial requirement groups. See [docs/requirements.md](https://github.com/gpt4free/g4f.dev/blob/main/docs/requirements.md).
- Provider selection: learn how to set defaults and override per-request at [docs/selecting_a_provider.md](https://github.com/gpt4free/g4f.dev/blob/main/docs/selecting_a_provider.md).
- Persistence: HAR files, cookies, and generated media persist in mapped directories (e.g., har_and_cookies, generated_media).

---

## Running on smartphone
- The web GUI is responsive and can be accessed from a phone by visiting your host IP:8080 or via a tunnel. See [docs/guides/phone.md](https://github.com/gpt4free/g4f.dev/blob/main/docs/guides/phone.md).

---

## Interference API (OpenAI‑compatible)
- The Interference API enables OpenAI-like workflows routed through GPT4Free provider selection.
- Docs: [docs/interference-api.md](https://github.com/gpt4free/g4f.dev/blob/main/docs/interference-api.md)
- Default endpoint (example slim docker): `http://localhost:1337/v1`
