The bagel they save for the regulars. Don't skim, savour.
Summary
Microsoft has launched seven in-house MAI models into its Foundry platform, unveiled at Build 2026. The lineup includes MAI-Thinking-1 as the flagship reasoning model, plus additional models for code generation, image processing, voice, and transcription. This marks a shift from a single-model release to a broader developer ecosystem push. Developers and enterprise teams get limited private-preview access first, as Microsoft moves more first-party AI systems toward customer testing. Foundry serves as Microsoft's platform for discovering, deploying, and governing AI models.
