# Portkey AI (/docs/configuration/librechat_yaml/ai_endpoints/portkey)

> Portkey API key: [app.portkey.ai](https://app.portkey.ai/)


**Notes:**
- LibreChat requires that the `API key` field is present. We don’t need it for the Portkey integration, we can pass a `dummy` string for it.
- Portkey integrates with LibreChat, offering observability, 50+ guardrails, caching, and conditional routing with fallbacks and retries for reliable, production-grade deployments.
- Portkey Supports 250+ Models, you can find the list of providers on [Portkey Docs](https://docs.portkey.ai/docs/integrations/llms)
- You can use Portkey in two ways—through [Virtual Keys](https://docs.portkey.ai/docs/product/ai-gateway/virtual-keys  ) or [Configs](https://docs.portkey.ai/docs/product/ai-gateway/configs).
- You can use Model specific parameters like `top_p`, `max Tokens`, etc. in using Portke Config. [Learn more](https://docs.portkey.ai/docs/product/ai-gateway/configs#configs)
