# Provider Switching

> Switch between LLM providers dynamically using Freeplay prompt configuration.

### 1. Create the necessary clients

### 2. Fetch the prompt from Freeplay

Freeplay will format your messages and model parameters for the provider you have configured on the prompt template version

### 3. Make the LLM call

Key off the provider name from the formatted prompt and route to the proper provider

### 4. Record to Freeplay

Record the interaction back to Freeplay
