 Let's modify the code above to make a call to Anthropic's `claude-3-opus-20240229` model.
 
-Portkey supports **[Virtual Keys](https://docs.portkey.ai/docs/product/ai-gateway-streamline-llm-integrations/virtual-keys)** which are an easy way to store and manage API keys in a secure vault. Lets try using a Virtual Key to make LLM calls. You can navigate to the Virtual Keys tab in Portkey and create a new key for Anthropic.

 The `virtual_key` parameter sets the authentication and provider for the AI provider being used. In our case we're using the Anthropic Virtual key.
