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 Character.AI?

Character.AI is becoming an interactive entertainment studio, absorbing comics and original series into its Character ecosystem.

Character.AI has made a clear pivot from conversational AI chatbot platform to interactive entertainment. The product now spans Microdramas (studio-made vertical series), comics, interactive Books, and Lorebook for creator worldbuilding — each format using Character interaction as its core primitive rather than as an add-on. Safety remains a persistent constraint: under-18 open-ended chat restrictions stay in place and public safety updates continue, reflecting ongoing legal scrutiny that shapes product decisions.

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.

Character.AI is becoming an interactive entertainment studio, absorbing comics and original series into its Character ecosystem.

◆ Current state

Character.AI has made a clear pivot from conversational AI chatbot platform to interactive entertainment. The product now spans Microdramas (studio-made vertical series), comics, interactive Books, and Lorebook for creator worldbuilding — each format using Character interaction as its core primitive rather than as an add-on. Safety remains a persistent constraint: under-18 open-ended chat restrictions stay in place and public safety updates continue, reflecting ongoing legal scrutiny that shapes product decisions.

◆ Where it's heading

Each new media format (comics, series, books) generates IP and Character richness that feeds back into the ecosystem. The creator layer — Lorebook, discovery features, creator bundles — is being built in parallel to enable user-generated Characters to power these formats rather than relying solely on studio output. The arc is a content platform where Characters are the connective tissue across media types.

◆ Prediction

The next format addition will likely be audio or IP licensing deals bringing established fictional universes onto the platform, following the pattern of absorbing existing media forms into the Character interaction layer.
