Microsoft has unveiled a suite of IQ products over the last few months. Work IQ, Fabric IQ, and Foundry IQ build on what Microsoft used to call its “Graphs,” the underlying data architecture that underpins its cloud services. These graphs provided a way to query the data your business uses, treating that data as nodes in a graph database and using the GraphQL API model to extract that data — for example, to pull data related to a specific individual held across the various Microsoft 365 applications.
The IQ suite follows a similar approach, using the same data, but treating it as the sparse vector store needed to provide grounding data for LLM-based applications. By treating the data as a set of embedding vectors, and integrating it with Model Context Protocol (MCP) servers, Microsoft is giving you the necessary tools to tie LLM output to your data, reducing the risk of hallucination and improving accuracy. Using your own data is a key part of delivering effective agents, ensuring they work within your constraints.
Extending IQ to the web
Web IQ, the latest member of the IQ suite, was unveiled at Build 2026. A modernization of the retired Bing Search APIs, Web IQ is an agent-focused web search tool that builds on the massive Bing search index to provide up-to-date general information for use in your applications.
