Microsoft pushes AI models via Update
- Microsoft is now shipping Copilot+ AI components through normal Windows Update, including KB5089865 for Intel PCs and KB5090939 for Qualcomm systems. (support.microsoft.com) - The Intel update installs Phi Silica version 1.2603.373.0 on Windows 11 26H1, while the Qualcomm package updates image processing to version 1.2604.515.0. (support.microsoft.com) - That matters because Microsoft is treating local models as serviceable OS components now — with separate release tracks, prerequisites, and enterprise management implications.

Windows Update is no longer just patching code. It is now delivering AI models and model-adjacent runtimes as first-class parts of the operating system on Copilot — local AI on Windows is becoming something Microsoft can revise, swap, and optimize on its own schedule through standard update plumbing. Microsoft published KB5089865 as a Phi Silica AI component update for Intel-powered Copilot+ PCs, and KB5090939 as an Image Processing AI component update for Qualcomm systems rather than as separate app downloads. ### What is Phi Silica? Phi Silica is Microsoft’s on-device small language model for Copilot+ PCs. It runs on the machine’s Neural Processing Unit, not in the cloud, and Microsoft says it handles tasks like text understanding, summarization, rewriting, and short-form generation for Windows features and apps. In plain English — this is the local language brain Microsoft wants sitting inside the OS. ### What is the Qualcomm update doing? The Qualcomm package is not a chatbot model. It is an image-processing component — the local stack that handles things like scaling, segmentation, foreground and background extraction, and visual analysis. Microsoft ties it to image understanding and AI-assisted editing workflows, again running on dedicated AI hardware in the device. ### Why is the delivery method the real news? Because Microsoft has spelled out that Copilot+ AI components are serviced independently through Windows Update as part of “Windows AI updates.” That means AI capabilities can change separately from the usual big Windows feature releases. Basically, models are being treated more like drivers or system components than optional software. ### Is this a one-off? No — it looks like a structured release system. Microsoft’s AI component release-history page lists separate component families, version numbers, dates, and KB articles for things like Phi Silica, Image Processing, Image Transform, Execution Provider, and Settings Model. So KB5089865 and KB5090939 are part of a broader servicing cadence, not random exceptions. ### Why should IT teams care? Once AI components ship this way, they become another managed layer on the endpoint. They have prerequisites, replacement chains, hardware-specific variants, and version drift. KB5089865, for example, requires the latest cumulative update for
