## Configuration Required

**Before using any model in your agent**, the platform operator must configure the model connection in the AgentSystems UI:

1. Navigate to **Configuration → Model Connections**
2. Add the model ID (e.g., `claude-sonnet-4`)
3. Select hosting provider (Anthropic, OpenAI, Bedrock, Ollama)
4. Configure authentication (API keys, AWS credentials, etc.)
5. Enable the connection

Agent builders reference the model ID in code, but the actual hosting provider and credentials are configured by whoever runs the AgentSystems platform.
