Microsoft announced Web IQ , a set of grounding APIs that let AI agents pull information from Bing’s search index. The company calls Web IQ “a search engine for AI systems.” Where Bing helps people find web pages, Web IQ helps AI agents find information they can use while reasoning through a task. What Web IQ Does Web IQ uses a rebuilt retrieval stack based on the Bing index, redesigning how content is indexed, ranked, and selected. AI agents search repeatedly under tight time constraints across multiple steps. The API returns passages and ‘structured evidence objects’ instead of full web pages, so AI models receive only the useful parts of a page. Every token an AI model processes costs money and adds latency, so fewer tokens with better information means cheaper and faster answers. Microsoft summarizes it as “fewer tokens in, better answers out, lower cost per call.” Performance Claims Microsoft uses GDSAT (grounding satisfaction) to measure if info is fresh and trustworthy.…
