Portkey AI
Configure Portkey AI as a custom endpoint in LibreChat.
Archived documentation
You are reading the frozen documentation for v0.8.7, which is no longer maintained. Go to the latest docs.
Portkey is an AI gateway that fronts 250+ models through an OpenAI-compatible endpoint, adding observability, 50+ guardrails, caching, and conditional routing with fallbacks and retries. See the full provider list in the Portkey docs.
Get an API key
Create a key at app.portkey.ai and add it to your .env file. You will also need a gateway URL, which Portkey provides for self-hosted or hosted gateways:
PORTKEY_API_KEY=your-api-key
PORTKEY_GATEWAY_URL=your-gateway-urlConfiguration
LibreChat requires the apiKey field, but Portkey does not use it, so pass the string dummy. Authentication happens through the x-portkey-* headers instead. There are two ways to connect, depending on whether you route by Virtual Keys or Configs. Add one of the following under endpoints.custom in your librechat.yaml.
Virtual Keys
- name: "Portkey"
apiKey: "dummy"
baseURL: ${PORTKEY_GATEWAY_URL}

x-portkey-api-key: "${PORTKEY_API_KEY}"

- Configs let you set model-specific parameters like
top_pandmax_tokenson the Portkey side. See the Configs docs. - Replace
PORTKEY_OPENAI_VIRTUAL_KEYandpc-libre-xxxwith the virtual key or config ID from your Portkey dashboard.
