OverviewFeaturesPricingGetting StartedUse CasesIntegrationsLimitationsFAQ

Overview

Databricks Mosaic AI Agent Framework is an enterprise-grade platform for building, evaluating, and deploying production AI agents directly on top of the Databricks Data Intelligence Platform. Designed for organizations that have already standardized on the Lakehouse architecture, the framework gives data and ML teams a unified path from raw documents and structured tables to governed, retrieval-augmented agents that can answer questions, summarize unstructured content, and act on enterprise data without leaving the Databricks security perimeter.

At its core, the framework combines four tightly integrated capabilities. First, Mosaic AI Vector Search provides a serverless, fully managed vector database that automatically syncs with Delta tables, so embeddings stay current as source data changes. Second, the Agent Framework SDK offers a code-first authoring experience built around MLflow, LangChain, and LlamaIndex, letting developers compose RAG pipelines, tool-calling agents, and multi-step reasoning chains using familiar Python patterns. Third, the Mosaic AI Agent Evaluation suite enables systematic quality measurement through LLM-as-judge metrics, human review apps, and offline test sets that catch regressions before deployment. Fourth, Model Serving and AI Gateway provide low-latency endpoints with rate limiting, payload logging, PII detection, and unified billing across both open-source models (Llama, Mistral, DBRX) and proprietary providers (OpenAI, Anthropic, Google).

What distinguishes Mosaic AI from horizontal agent frameworks is its native integration with Unity Catalog, which extends row-level security, column masking, and lineage tracking directly into agent responses. This means an agent automatically respects the same data permissions a user has when querying tables, and every retrieval, tool call, and model invocation is logged for audit and governance. The platform also includes Agent Bricks, a newer AutoML-style capability that automatically optimizes RAG pipelines, instructed retrievers, and document intelligence workflows based on a customer's evaluation data, reducing the manual tuning typically required to reach production quality.

Mosaic AI is best suited for enterprises whose data already lives in Databricks or that are willing to consolidate on the Lakehouse for both analytics and AI workloads. Pricing follows the consumption-based DBU model used across Databricks, with separate charges for vector search, model serving throughput, and agent evaluation runs. While the platform offers depth that pure-play agent frameworks cannot match, it carries the learning curve and operational footprint of the broader Databricks ecosystem.

        Frequently Asked Questions

        What types of knowledge assistant use cases does Databricks Mosaic AI support best?+

        Databricks Mosaic AI excels at document-based knowledge applications including product documentation search, internal policy Q&A, customer support knowledge bases, and regulatory compliance assistants. It is strongest when the knowledge sources are already stored in or can be loaded into Unity Catalog Volumes, and when governance and auditability are requirements.

        How does the Instructed Retriever technology improve upon traditional RAG approaches?+

        Instructed Retriever technology teaches the system when and how to retrieve information based on the specific domain and query patterns, rather than relying solely on generic vector similarity. This approach optimizes chunk selection, reranking, and context assembly automatically, resulting in 15–25% retrieval relevance improvements in enterprise document corpora compared to standard vector-search RAG.

        Can Databricks knowledge assistants work with existing enterprise data without migration?+

        Yes, through Unity Catalog integration, knowledge assistants work directly with existing Delta tables, files in Unity Catalog Volumes, and connected external data sources via JDBC connectors. Organizations can reference data in S3, Azure Blob Storage, or GCS without moving it, though performance is best when data resides within the Lakehouse.

        What are the language and file format limitations for knowledge sources?+

        Currently, only English language content is supported. Supported file formats include txt, pdf, md, ppt/pptx, and doc/docx, with a maximum file size of 50 MB per document. Scanned PDFs without OCR text layers may produce lower-quality results. Structured data in Delta tables can also serve as knowledge sources.

        How does MLflow evaluation help improve knowledge assistant quality over time?+

        MLflow provides systematic evaluation frameworks that track response quality through both automated LLM-as-a-judge scoring (groundedness, relevance, safety, chunk relevance) and human expert feedback. Teams can define evaluation datasets, run automated regression tests before deployments, and monitor production quality metrics over time to catch degradation early.

        What level of Databricks platform commitment is required to use Mosaic AI effectively?+

        Effective use requires comprehensive Databricks platform adoption including Unity Catalog for governance, serverless or provisioned compute for model serving, and Vector Search for retrieval. Organizations need an active Databricks workspace with Unity Catalog enabled. While agents can call external APIs, the core infrastructure must run on Databricks.

        How much does Databricks Mosaic AI cost compared to building a custom RAG stack?+

        Databricks charges ~$0.07/DBU for most AI workloads with GPU Model Serving endpoints ranging from $0.10–$0.22/DBU. A typical knowledge assistant serving moderate traffic (10K queries/day) may consume 50–200 DBU-hours daily, translating to roughly $100–$500/month in serving costs alone, plus Vector Search and compute DBUs. By comparison, assembling a standalone stack (Pinecone + LangChain + separate hosting) often runs $500–$2,000/month at similar scale but lacks built-in governance and evaluation. Organizations already on Databricks see 30–50% lower marginal cost since infrastructure is shared.
