Databricks Mosaic AI — Enterprise AI infrastructure for production-grade agents
What It Does: Mosaic AI is Databricks' unified platform for building, deploying, and governing AI agents and models. It combines foundation model serving, vector search, agent frameworks, and AI gateway governance into a single stack that sits on your existing data lakehouse. Think of it as the full MLOps pipeline—from training to deployment to monitoring—without stitching together 15 different tools.
Pricing:
Tier | Price | Limits | Use Case |
|---|---|---|---|
Pay-per-token | $0.001–$0.01/1K tokens | No commitment | Experimentation, prototyping |
Provisioned Throughput | ~$0.07–$0.65/DBU | Reserved capacity | Production workloads |
Premium Workspace | ~$0.55/DBU | RBAC, audit logs, governance | Enterprise teams |
Enterprise Workspace | ~$0.65+/DBU | HIPAA, FedRAMP compliance | Regulated industries |
Who It's For:
Data teams with existing Databricks — Native integration means zero migration friction
Enterprise ML engineers — Production-grade serving with auto-scaling and governance
Compliance-heavy organisations — Built-in guardrails, audit logging, and data lineage
Teams building RAG pipelines — Vector Search + Agent Framework handles the full stack
What Makes It Different:
Unified governance — AI Gateway provides rate limiting, fallbacks, traffic splitting, and guardrails across any model (OpenAI, Anthropic, Meta, custom)
Any model, one API — Query GPT-4, Claude, Llama, or your fine-tuned model through identical endpoints
Data-native — Your agents can query Unity Catalog tables directly—no ETL to a separate vector database
Agent evaluation built-in — AI judges measure output quality so you can iterate before production
Core Capabilities:
Foundation Model Serving (GPT-4, Claude, Llama, Gemini)
Mosaic AI Vector Search with hybrid retrieval
Agent Framework for RAG and multi-step agents
Model Training for fine-tuning on proprietary data
AI Gateway for governance, monitoring, and cost control
Limitations:
DBU pricing is complex—costs can spike unexpectedly without monitoring
Requires Databricks ecosystem commitment; not a standalone tool
Enterprise features (HIPAA, FedRAMP) require highest-tier pricing
The Verdict: If you're already on Databricks and need to ship AI agents to production with enterprise governance, Mosaic AI is the obvious choice. If you're a startup exploring, the pay-per-token experimentation tier keeps costs low while you validate use cases.
