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 Dosu?

The OSS terms change takes effect today, under a steady drumbeat of agent-memory explainers.

Dosu's feed is currently doing two jobs. One is a sustained series on agent memory — representation and storage, the building blocks of a memory system, where knowledge should live — published as a webinar and then a blog write-up of the same material. The other is the announced change to its open source plan, which takes effect 1 September 2026 and which Dosu says leaves roughly 96% of projects unaffected. The actual product releases sit just outside this window, in the monthly Drop posts and the Decant launch that reads Claude Code and Codex session logs locally.

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 OSS terms change takes effect today, under a steady drumbeat of agent-memory explainers.

◆ Current state

Dosu's feed is currently doing two jobs. One is a sustained series on agent memory — representation and storage, the building blocks of a memory system, where knowledge should live — published as a webinar and then a blog write-up of the same material. The other is the announced change to its open source plan, which takes effect 1 September 2026 and which Dosu says leaves roughly 96% of projects unaffected. The actual product releases sit just outside this window, in the monthly Drop posts and the Decant launch that reads Claude Code and Codex session logs locally.

◆ Where it's heading

The content is doing positioning work around the pricing boundary rather than filling time. The argument running through it — that a coding agent's budget goes to context rather than code, that most teams should start with Git as the memory substrate, that old agent logs are worth converting into maintained knowledge — all points at the same claim, that the durable asset is stored knowledge and Dosu is where it should live. The OSS terms change tests whether that argument stands on its own once the largest repositories are no longer free distribution.

◆ Prediction

Expect the September Drop to show how the new OSS terms landed in practice, and the memory series to close on a Dosu-shaped answer to where knowledge lives.
