ResponsesAgent Patterns

MLflow ResponsesAgent is MANDATORY for all new Databricks GenAI agents. It provides automatic signature inference, AI Playground compatibility, built-in tracing, and streaming support.

When to Use

• Creating a new Databricks GenAI agent
• Implementing streaming responses (predict_stream)
• Configuring OBO authentication for Model Serving
• Adding MLflow tracing to agent functions
• Troubleshooting AI Playground compatibility
• Setting up Automatic Auth Passthrough for resources

Critical Rules

1. ResponsesAgent is MANDATORY (Not ChatAgent, Not PythonModel)
