# TrueFoundry AI Gateway (https://www.librechat.ai/docs/configuration/librechat_yaml/ai_endpoints/truefoundry)

TrueFoundry AI Gateway is an enterprise proxy layer between your applications and LLM providers, giving access to 1000+ models through a unified OpenAI-compatible interface with built-in observability and governance.

## Get an API key

Authenticate with a Personal Access Token. Generate one by following the [PAT guide](https://docs.truefoundry.com/gateway/authentication#personal-access-token-pat), then add it along with your gateway URL to your `.env` file:

```bash filename=".env"
TRUEFOUNDRY_API_KEY=your-api-key
TRUEFOUNDRY_GATEWAY_URL=your-gateway-url
```

Get the gateway URL and model names from the unified code snippet in the TrueFoundry console. Use the same model names you added to the gateway. The [quick start guide](https://docs.truefoundry.com/gateway/quick-start) walks through setup.

## Configuration

Add the endpoint under `endpoints.custom` in your `librechat.yaml`:

```yaml filename="librechat.yaml"
    - name: "TrueFoundry"
      apiKey: "${TRUEFOUNDRY_API_KEY}"
      baseURL: "${TRUEFOUNDRY_GATEWAY_URL}"
      models:
        default: ["openai-main/gpt-4o-mini", "openai-main/gpt-4o"]
        fetch: true
      titleConvo: true
      titleModel: "current_model"
      summarize: false
      summaryModel: "current_model"
      modelDisplayLabel: "TrueFoundry:OpenAI"
```

## Notes

- Model names are namespaced by the integration you configured in the gateway, such as `openai-main/gpt-4o`. Match them to the names shown in your TrueFoundry console.
