Other ways to build agents

This page covers other ways to build agents on Databricks.

For new agents written in code, Databricks recommends the Agent Bricks CLI, which serves your agent with DurableAgentServer and deploys it to Agent Runtime. See Deploy agents on Databricks. For new agents built without code, use Genie Agents.
