# Using OpenAI-Compatible APIs

> Presenton supports OpenAI-compatible APIs, allowing you to connect to any custom LLM backend that follows the OpenAI API format.

### 🌐 Example: Run Presenton with a Custom LLM

```bash theme={null}
docker run -it --name presenton -p 5000:80 \
  -e LLM="custom" \
  -e CUSTOM_LLM_URL="http://XXXXXXXXXXX/v1" \
  -e CUSTOM_LLM_API_KEY="your_custom_api_key" \
  -e CUSTOM_MODEL="your-model-name" \
  -e IMAGE_PROVIDER="pexels" \
  -e PEXELS_API_KEY="xxxxxxxxxxx"
  -e CAN_CHANGE_KEYS="false" \
  -v "./app_data:/app_data" \
  ghcr.io/presenton/presenton:latest
```
