Snowflake's Horizon Context aims to give AI agents a common understanding of the business

Snowflake is attempting to address that problem with Horizon Context, a new set of semantic and metadata-management capabilities, currently in preview, that it unveiled Tuesday at its annual Snowflake Summit conference. Artin Avanes, head of core data platform at Snowflake, said that the offering, launched as part of Horizon Catalog, the company's existing data discovery, management and governance suite, collects metadata from across an enterprise's data estate, enriches it with business definitions, relationships, lineage, and governance information, and makes that context available across AI and analytics systems. These capabilities, according to Avanes, build on Snowflake's acquisition last year of Select Star, a metadata management startup known for its integrations with database systems such as PostgreSQL and MySQL, business intelligence tools like Tableau and Power BI, and data pipeline/orchestration tools such as dbt and Airflow. Reducing operational complexity of agentic workflows For CIOs, Horizon Context should reduce operational complexity because it will provide a governed map of their organization's data estate, said Stephanie Walter, practice lead of the AI Stack at HyperFRAME Research. "The value is not simply cataloging where data lives; it is giving AI systems the metadata, lineage, permissions, and business context needed to retrieve the right data safely," Walter said.

Why AI agents give confident wrong answers

Enterprise AI agents have a new production failure mode, and it is not the model. As enterprises move from single-layer RAG to hybrid retrieval architectures, the same underlying data produces different answers depending on which agent, tool or system asks the question. Revenue means one thing in a business intelligence (BI) dashboard, something slightly different in a SQL table and something else again in an agent instruction. The retrieval infrastructure build-out of the past two years produced faster and cheaper vector search. It did not produce a shared definition of what the data means. At Snowflake Summit 26 in San Francisco, the data cloud vendor is taking a broad swing at that problem, with announcements spanning a Kafka-compatible managed streaming service called Data Stream, adaptive compute improvements, expanded Apache Iceberg interoperability and updates to its Cowork and CoCo agent and coding products. Running underneath all of it is a context layer: Horizon Context and Cortex Sense, a two-layer system designed to give agents a governed, shared definition of business logic across retrieval stacks. The context problem is why it matters: VentureBeat's VB Pulse Q1 2026 data, drawn from a survey of organizations with 100 or more employees, shows hybrid retrieval intent tripling from 10.3% in January to 33.3% in March, the fastest-growing strategic position in the dataset. "There are a lot of tools out there that you can ask questions, you get a very confident answer, but whether it's correct or not is different," said Christian Kleinerman, EVP of Product at Snowflake. From fragmented business logic to a governed context layer The problem Horizon Context targets is specific. Business logic today is distributed across SQL, BI dashboards and agent instructions, and no single system owns the definition. When multiple agents or tools query the same underlying data, they reason over different schemas and return different answers. Horizon Context is Snowflake's attempt to fix that at the catalog layer rather than at the agent layer. Horizon Context. The customer-managed layer, built on Snowflake's acquisition of Select Star. It pulls metadata from Postgres, SQL Server, Tableau and Power BI into the Horizon Catalog, so every agent, BI tool and external system draws from the same governed definition rather than reasoning independently over a raw physical schema. Semantic View Autopilot automatically creates and refines semantic views over time, extending curated business logic without requiring ongoing manual effort. Cortex Sense. The platform-derived layer. It automatically builds and enriches context from customer data and usage patterns on an ongoing basis, without requiring manual semantic view authoring. Kleinerman described it as improving the default experience before any explicit curation has happened. The distinction between the two layers is architectural and Kleinerman was precise about it. "Think of Horizon Context as everything that is explicit and declared by customers, and Cortex Sense is anything that is implicit and derived by us," Kleinerman said. The two layers connect to Snowflake's existing retrieval infrastructure. Cortex Search, the company's RAG implementation, plugs into both CoCo and Cowork as a tool, so context enriched by either layer flows into retrieval workflows. While Horizon Context is a Snowflake technology, the goal is for it to be interoperable and open. Snowflake is tying the technology to the Open Semantic Interchange, making customer-declared definitions portable across third-party catalogs and tools. "Horizon Context, 100% we're committed to and leading the effort to make sure that that's not locked in," Kleinerman said. Context layers are everywhere. The question is which ones actually work. Snowflake is joining an increasingly crowded field of vendors targeting the same problem. Microsoft has opened its Fabric IQ business ontology via MCP so any vendor's agent can draw from a shared semantic layer. Redis launched Iris, a context and memory platform that sits between agents and their data, built on a storage engine redesigned for agent-scale retrieval volumes. Pinecone is repositioning from vector database to knowledge engine with Nexus, which compiles enterprise data into task-specific artifacts before agents ever query them. Devin Pratt, research director at IDC, told VentureBeat that in his view Snowflake is headed in the right direction and is going where the whole market is heading. "Agents are only as good as the data and semantics behind them, so the context layer, not the model, is the thing to watch right now," Pratt said. In Pratt's view, what works about Snowflake's version is the split. Horizon Context covers what teams declare and curate themselves, and Cortex Sense covers what the platform picks up automatically. Just as important, they've anchored Horizon Context inside the catalog and governance layer rather than bolting it on after the fact. "The context layer is the real battleground for agentic AI. An agent is only as trustworthy as the data and semantics behind it" Pratt said. Mike Leone, VP and principal analyst at Moor Insights and Strategy, agreed that treating the two layers differently is the right architectural call. "I like where Snowflake's heading. They're splitting context into two buckets, with Horizon Context covering what customers explicitly define and Cortex Sense covering what the platform figures out on its own," Leone told VentureBeat. "You can't trust those two things the same way, so treating them differently is the right call. If Snowflake can show those two layers reconcile cleanly and you can see where every answer came from, they've got something real." What this means for enterprises For enterprises evaluating context layers, the architectural direction is clear. The execution gap is not. Agents raise the bar on an old problem. The semantic layer idea has existed for years, but agents change what failure costs -- when an agent gives a wrong answer at scale, the damage is immediate. Leone is direct about what that means for most vendors currently in the market. "Most vendors selling a drop-in fix are overpromising," Leone said. "Drop one into a real enterprise and it mostly exposes how messy your data and definitions already are, and a lot of companies are about to find that out the hard way." The evaluation bar is specific. Pratt identified what separates context layers that work from those that stall: governance and lineage built in so teams can audit why an agent gave the answer it did, portability so context and policy are not locked to one vendor, and accuracy that can be measured and reused across agents and tools. "Enterprises don't need another silo of semantics," Pratt said. "They need a context layer that's governed, portable, and trustworthy enough to audit."

Enterprise context layer in focus as enterprises scale AI

As enterprise AI matures, data and context emerge as new competitive edge Enterprise AI is entering a new phase where competitive advantage depends less on foundation models and more on the ability to connect data and business knowledge through an enterprise context layer. As organizations scale AI initiatives, intelligent agents are emerging as the new interface between information and action. Many organizations had written off big data after years of unmet expectations, but generative AI is finally unlocking the value that massive datasets promised all along. The challenge now is not recognizing the importance of enterprise data, but overcoming the complexity of connecting and operationalizing it for AI-driven applications, according to Bob O'Donnell (pictured, right), founder and chief analyst of TECHnalysis Research LLC. "It makes so much sense because people have recognized, to make AI productive and effective in their organization, they obviously have to tap into their own data," O'Donnell said. "That sounds great in theory, but it turns out the nuts and bolts of actually doing that are pretty darn hard." O'Donnell and Sanjeev Mohan (left), founder and owner of SanjMo, spoke with theCUBE's Dave Vellante at Snowflake Summit 2026, during an exclusive broadcast on theCUBE, SiliconANGLE Media's livestreaming studio. They discussed how generative AI is finally delivering on the long-promised value of big data and why the enterprise context layer is emerging as the foundation for the next generation of AI agents. (* Disclosure below.) Enterprise context layer in focus Many organizations recognize that effective AI initiatives require a strong data foundation, but the complexity of consolidating and organizing enterprise data has made unified platforms and an enterprise context layer increasingly important advantages. Today, organizations are moving away from centralized data warehouse strategies and toward federated approaches that allow data to remain in place while being connected and analyzed across systems, according to Mohan. "The entire attempt to create a corporate data warehouse is fraught with problems,", Mohan said. "It's not for everybody." Data federation has gained momentum as organizations increasingly access and analyze data where it resides rather than moving it into centralized repositories. Faster networks, reduced data-transfer costs and the adoption of open standards such as Apache Iceberg have made this approach far more practical at scale, according to Mohan. "You can leave data where it is ... but now the moat has moved to a layer above it, which is the context layer or the metadata layer because you can apply security there," Mohan said. "You can disambiguate what is the meaning of customer in SAP. This whole SAP-Snowflake bidirectional metadata sync, is a game changer in my opinion." Traditional semantic layers were designed for structured data, but modern AI environments must also incorporate semi-structured and unstructured information. As a result, organizations are increasingly building context layers or knowledge graphs that agents can then query across tools like Slack and Jira, Mohan explained. For O'Donnell, that shift represents a fundamental architectural leap -- from systems that retrieve and respond to ones that remember and reason. "There's no memory, there's no state being maintained," O'Donnell said. "I think we are finally getting to a point where I can fine-tune or train a small model. That has not yet happened -- but that's coming."
