No free plan. The cheapest way in is Foundation Model Serving at From $0.07/DBU. Consider free alternatives in the ai agent frameworks category if budget is tight.
Mosaic AI is part of the Databricks platform and uses DBU-based pricing. Foundation model serving starts at $0.07 per DBU. Serverless SQL for agent analytics runs up to $0.70 per DBU. Total cost depends on inference volume, retrieval frequency, and compute tier. There is no flat monthly agent fee. Contact Databricks sales for a cost estimate based on your expected workload.
No. The Agent Framework is tightly integrated with the Databricks Lakehouse, Unity Catalog, and Model Serving. It is not available as a standalone product. If you are evaluating agent frameworks without an existing Databricks investment, platforms like LangChain, CrewAI, or AWS Bedrock Agents have lower entry barriers.
Model Context Protocol (MCP) is a standard for connecting AI agents to external tools. Mosaic AI supports MCP as both client (your agents can call external tools) and server (external agents can access your Lakehouse). This enables multi-platform agent architectures where Databricks handles data-heavy reasoning while other systems handle actions like sending emails or updating CRMs.
Agent Evaluation lets you define quality criteria using three methods: rule-based checks (response length, format compliance), LLM-as-judge scoring (an LLM grades agent responses for accuracy and relevance), and human review (team members rate responses in an integrated UI). You run evaluation sets against agent versions and compare scores before deploying to production.
