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 GitHub Copilot?

The Agents window now opens without a GitHub sign-in, if you bring an Anthropic key.

August's VS Code releases (v1.132 through v1.135) concentrated on the Agents window: chats arranged side by side, a /btw side conversation that shares the parent chat's context and prompt cache, a prompt timeline for navigating long transcripts, and Agent Host connecting one session across multiple windows. The notable items are the ones that loosen GitHub's grip on its own surface — an experimental setting opens the Agents window without a GitHub sign-in when Claude is configured with an API key, model providers can be switched between Anthropic and Copilot subscriptions mid-session, and sessions started in other applications can be listed and continued in VS Code. Plugins following the Agent Plugins 1.0 standard install across VS Code and other compatible clients.

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.

The Agents window now opens without a GitHub sign-in, if you bring an Anthropic key.

◆ Current state

August's VS Code releases (v1.132 through v1.135) concentrated on the Agents window: chats arranged side by side, a /btw side conversation that shares the parent chat's context and prompt cache, a prompt timeline for navigating long transcripts, and Agent Host connecting one session across multiple windows. The notable items are the ones that loosen GitHub's grip on its own surface — an experimental setting opens the Agents window without a GitHub sign-in when Claude is configured with an API key, model providers can be switched between Anthropic and Copilot subscriptions mid-session, and sessions started in other applications can be listed and continued in VS Code. Plugins following the Agent Plugins 1.0 standard install across VS Code and other compatible clients.

◆ Where it's heading

Copilot is increasingly a host rather than a destination. The portable plugin standard, the cross-application session list, and the provider switcher all treat the model and the customizations as things the user brings, which is consistent with GitHub publishing Agent Plugins 1.0 as a shared spec rather than a proprietary format. The counterweight is administrative: policy and billing changes were pre-announced this month and a global model policy reached general availability, so the client layer opens while control consolidates in enterprise settings.

◆ Prediction

Expect the sign-in-free Agents window and the /rubber-duck second-opinion command to graduate out of experimental, and enterprise policy to gain per-provider controls now that non-Copilot subscriptions can drive sessions.
