Microsoft also unveiled three new products at its recent Build 2026 conference to strengthen data infrastructure for AI agents.

Amir Netz (아미르 네츠), CTO of the Microsoft Fabric unit, said, “Enterprise AI should be like an insider who knows how an organisation works.” He added, “For agents to operate in a trustworthy way, they need the organisation’s memory, a ‘context layer.’”

To that end, Microsoft first announced Azure HorizonDB.

According to a report by TheNewsStack, it is a fully managed PostgreSQL-compatible database and will be available as a public preview. It supports up to 128TB of storage, 3,072 virtual cores of computing and sub-millisecond latency. It also includes vector search, AI model management and direct connectivity to Microsoft Foundry and Fabric.

Microsoft will also support Nvidia GPU acceleration for Fabric Data Warehouse. It plans to offer it as an early access preview in July 2026. Microsoft said internal benchmarks showed performance up to 7 times faster than three rival cloud data warehouses. Netz said, “In data warehousing, even a 10 percent annual performance improvement is a big achievement, but with GPU acceleration we are seeing 5 to 100 times improvement.”

Microsoft also officially launched Fabric IQ. Based on the Power BI data definition framework, Fabric IQ adds core business concepts such as customers, orders and products, along with their relationships, processing rules and real-time data signals. It also sets boundaries for what AI agents can and cannot do.

It also integrates with major Microsoft AI products such as Microsoft Foundry, Agent 365, Microsoft 365 Copilot and GitHub Copilot CLI, allowing AI agents in those products to share and use Fabric IQ’s enterprise context. Netz said, “By adding future predictions to past and present data, the ontology now covers all tenses.”

Microsoft is seeking to differentiate Fabric from Snowflake and Databricks, which are mainly specialised in analytics, by saying Fabric handles real-time operational data and analytics data on a single platform, TheNewsStack reported.
