Picture the scene: Before an executive business review, your VP of Sales asks an AI assistant, “What was net revenue for our top enterprise accounts last quarter?” In seconds, the agent returns a polished chart! Unfortunately, the numbers don’t match the finance report. Why? Because the agent counted cancelled orders as revenue and pulled from an unvalidated staging table.
The agent didn’t fail because of the model, or because it couldn’t translate a user question into a query. It failed because it didn’t understand your business. The real kicker is that understanding usually already exists in the form of a semantic model in a Looker, dbt, Snowflake, Databricks, or SAP system. But because each definition stays locked inside its own tool, every agent guesses at it… and often gets it wrong.
This is where Knowledge Catalog comes in. It brings the semantic models from all of those tools into one context graph, so every agent works from the same trusted definitions. And when two tools define the same metric differently, both definitions appear with their provenance, so data stewards can reconcile the conflict before it reaches end users.
Today, we’re announcing the general availability of expanded semantic model support. Knowledge Catalog now natively ingests semantic models and metric definitions from Looker LookML, BigQuery Graph (including BigQuery measures), dbt MetricFlow, Snowflake Semantic Views, Databricks Metric Views, and SAP Core Schema Notation (CSN), and connects them with schema, lineage, data profiles, business glossary and other key metadata in a single context graph, without moving data or rewriting business logic in a new language.
By grounding your AI agents in those models, they get the same business definitions your analysts rely on, so their answers line up with the numbers your business trusts. In fact, based on internal benchmarks, grounding agents in Knowledge Catalog makes them nearly 4X more accurate, with up to 33% lower latency, and using up to 75% fewer tokens.
The unified context graph enables you to:
-
Reuse the semantic models you already trust: Knowledge Catalog grounds Gemini agent, BigQuery Conversational Analytics, and your custom agents in the metrics, filters, and join paths your teams have already defined, wherever they live.
-
Go beyond hand-curated definitions with self-learned context: Knowledge Catalog pairs the well-defined metrics and KPI definitions in your semantic models with relevant context it extracts from unstructured knowledge sources, such as operational playbooks, meeting notes, chat threads, code, and more. Powered by Gemini, self-learning enrichment continuously finds missing or outdated context and turns it into governed, reusable context sets, ensuring your agents’ context stays current as definitions change, without relying only on manual curation.
-
Pair business logic with enterprise trust: Even the right formula produces the wrong answer when it runs on stale or uncertified data. That’s why Knowledge Catalog can connect semantic definition to data quality scores, freshness signals, and lineage, so an agent knows what it can trust before it writes a line of SQL.
