100-word summary
Microsoft just quintupled how much knowledge you can stuff into a Copilot agent. Each custom assistant can now ingest 512 MB of embedded files, up from around 100 MB, and pull from 100 SharePoint files instead of the previous handful. Think entire product catalogs, compliance manuals, or deal histories feeding a single bot. The update also ships government-cloud access, so defense contractors and federal agencies can finally build agents without moving to commercial tenants. Meanwhile, a pay-as-you-go API lets developers query SharePoint and other internal sources without buying Copilot seats for every user. The shift is clear: Microsoft wants you building dozens of specialized agents, not one generic chatbot.
