The Morning Build for August 15, 2026: Microsoft Merges Copilot Apps and Meta’s 6,500-Word AI Manifesto

Microsoft is consolidating its consumer and Microsoft 365 Copilot apps and pruning features, while Meta published a 6,500-word AI manifesto alongside an open-weight model release; both moves signal platform repositioning around who gets access to AI and which features companies will keep.

Microsoft merges consumer and Microsoft 365 Copilot apps and will remove several Copilot features by August 18, 2026

  • What happened: Microsoft will combine its consumer Copilot app with Microsoft 365 Copilot and remove features including Group Chats, AI-generated podcasts, Copilot Labs experimental features, and Deep Research for consumers by August 18, 2026; files from the stand-alone Copilot app will be migrated to OneDrive. Microsoft will also retire the Copilot animated character Mico and warns some features may temporarily disappear during the transition.
  • Why it matters: Engineers and product teams who integrate or build on Copilot face changes to available endpoints and user flows: consumer features listed will be removed and content will move to OneDrive, which affects storage, migration, and UX assumptions for applications relying on those Copilot-specific artifacts. Professional users will see Researcher offered as a replacement for Deep Research, which may shift where advanced search and research capabilities surface for paid workflows.
  • Outlook: August 18, 2026 is the customer-facing cutoff when the listed consumer features stop appearing and the migration to OneDrive is expected to be in effect.

Mark Zuckerberg publishes a 6,500-word AI manifesto as Meta promotes open-weight Muse Glimmer

  • What happened: Meta CEO Mark Zuckerberg published an approximately 6,500-word essay arguing for broad access to powerful models and positioning open access as an antidote to concentrated AI power; Wired notes Meta announced a new open-weight system called Muse Glimmer where users can download and modify the model.
  • Why it matters: Engineers tracking model availability and governance should treat Meta’s manifesto and Muse Glimmer release as a public statement of intent for more permissive, downloadable models rather than tighter, closed-hosted approaches, which affects dependency risk, distribution models, and potential replication of work on downstream infrastructure.
  • Outlook: The public release of Muse Glimmer and any follow-on open-weight model rollouts that Meta announced in conjunction with the manifesto are the next concrete milestones to watch for evidence of Meta’s stated shift toward broad access.
