What is Microsoft Bing?

Bing pivots from ranking pages to grounding AI, shipping APIs and an open embedding model

Bing is repositioning its search index as the grounding layer for AI assistants rather than a destination for human browsing. Recent shipping reflects this: Web IQ grounding APIs, an open-source embedding model topping MTEB-v2, and AI-citation reporting for publishers in Webmaster Tools. The consumer-facing image-search refresh is the exception in an otherwise infrastructure-and-publisher-tooling agenda.

What is Claude?

Ships a frontier model roughly monthly; now ships the controls in the same release.

Two model launches in under four weeks — Sonnet 5 on June 30, Opus 5 on July 24 — with Opus 5 positioned near Fable 5's intelligence at half the price. Around the models the surface area keeps widening: Cowork moving to web and mobile with sessions running remotely, a Microsoft 365 connector that writes instead of only reading, and now memory that spans chat and Cowork alike. The admin track has kept pace with Trusted Devices, model entitlements, self-serve HIPAA, and scanning for third-party skills and plugins.

Bing pivots from ranking pages to grounding AI, shipping APIs and an open embedding model

◆ Current state

Bing is repositioning its search index as the grounding layer for AI assistants rather than a destination for human browsing. Recent shipping reflects this: Web IQ grounding APIs, an open-source embedding model topping MTEB-v2, and AI-citation reporting for publishers in Webmaster Tools. The consumer-facing image-search refresh is the exception in an otherwise infrastructure-and-publisher-tooling agenda.

◆ Where it's heading

The throughline across entries is grounding: feeding fresh, verifiable web data to agents and assistants, then giving publishers visibility into how their content gets cited. Bing is building the supply side (APIs, embeddings) and the measurement side (citation share, intents, topics) of the AI-answer economy simultaneously. The framing essays signal Microsoft intends to own grounding as a category.

◆ Prediction

Expect the Webmaster Tools AI-visibility previews to reach GA and Web IQ to add pricing tiers or expanded data types as it courts third-party agent builders.

Ships a frontier model roughly monthly; now ships the controls in the same release.

◆ Current state

Two model launches in under four weeks — Sonnet 5 on June 30, Opus 5 on July 24 — with Opus 5 positioned near Fable 5's intelligence at half the price. Around the models the surface area keeps widening: Cowork moving to web and mobile with sessions running remotely, a Microsoft 365 connector that writes instead of only reading, and now memory that spans chat and Cowork alike. The admin track has kept pace with Trusted Devices, model entitlements, self-serve HIPAA, and scanning for third-party skills and plugins.

◆ Where it's heading

The pattern through most of this window is reach first, govern second: each capability that puts Claude inside someone's workplace is followed within weeks by a control that constrains it. The memory release breaks that order — cross-surface recall, per-item editing, and a sensitive-topics boundary all land together, with the default set by plan rather than by the user. If that sequencing holds, governance stops trailing capability and starts shipping as part of it.

◆ Prediction

Expect the same simultaneous treatment applied to Cowork's remote sessions and connector write permissions, where controls are still catching up. Whether skill and plugin scanning leaves Enterprise beta is the clearest near-term signal that the governance track is being generalized rather than sold upmarket.
