Microsoft Launches Three Proprietary AI Models (MAI-Transcribe-1, MAI-Voice-1, MAI-Image-2) — First Post-Suleyman Reorganization

TechCrunch·high signal

Microsoft released three in-house AI models on April 2: MAI-Transcribe-1 (state-of-the-art speech-to-text across 25 languages at ~50% lower GPU cost than alternatives), MAI-Voice-1 (60 seconds of expressive audio in under 1 second, voice cloning from 10-second samples), and MAI-Image-2 (debuted #3 on Arena.ai image leaderboard). This is Microsoft's first major model release since Suleyman's March reorganization, signaling an accelerated push to build proprietary AI capabilities beyond its OpenAI partnership. All three power Copilot, Bing, and PowerPoint internally.
