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 ONNX Runtime?

ONNX Runtime is dismantling itself into plug-ins — CUDA is now the one that ships separately.

ONNX Runtime is running two release tracks at once: the numbered core releases (1.25 through 1.29) and a growing set of separately versioned plug-in execution providers. WebGPU broke out first in May, and CUDA has now followed with its own 0.1.0. The core releases in between are dominated by security hardening, opset upgrades and deprecation notices rather than new capability.

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.

ONNX Runtime is dismantling itself into plug-ins — CUDA is now the one that ships separately.

◆ Current state

ONNX Runtime is running two release tracks at once: the numbered core releases (1.25 through 1.29) and a growing set of separately versioned plug-in execution providers. WebGPU broke out first in May, and CUDA has now followed with its own 0.1.0. The core releases in between are dominated by security hardening, opset upgrades and deprecation notices rather than new capability.

◆ Where it's heading

The direction is a smaller core binary with accelerators attached at runtime. The 1.26 notes stated the intent outright — CUDA moving to a dedicated execution provider rather than a package shipped from core — and 0.1.0 delivers it, with version-gated callbacks maintaining compatibility back to 1.24.4. Alongside that, the deprecation list keeps growing: CUDA 11, then CUDA 12, WebGL and JSEP, ArmNN, the duktape WGSL generator. Web inference is being consolidated onto WebGPU and native inference onto plug-ins.

◆ Prediction

Expect the plug-in EPs to take over release cadence from the core, with CUDA 12 removed in 1.27 as announced and further backends following WebGPU and CUDA out of the main binary.
