Databricks Mosaic AI Agent Framework - Pros & Cons
Pros
- ✓Agents query Lakehouse tables and Unity Catalog assets directly, no ETL required
- ✓Agent Evaluation suite combines automated checks and human review in one workflow
- ✓MCP support in both directions connects agents to the broader tool ecosystem
- ✓AI Gateway provides centralized cost tracking, rate limiting, and model routing
- ✓Governance is built in, not bolted on: lineage, access control, and audit trails come standard
- ✓Model-agnostic: use Databricks-hosted models, OpenAI, Anthropic, or open-source models through the same framework
Cons
- ✗Requires an existing Databricks platform investment, creating significant vendor lock-in
- ✗DBU-based pricing is difficult to predict without modeling expected query volumes
- ✗Steep learning curve for teams not already familiar with the Databricks ecosystem
- ✗No free tier or self-serve trial for agent-specific features
- ✗Serverless SQL costs ($0.70/DBU) can escalate quickly for analytics-heavy agent workloads
