Microsoft Launches Three Proprietary AI Models (MAI-Transcribe-1, MAI-Voice-1, MAI-Image-2) via Microsoft Foundry, Challenging OpenAI and Google

Microsoft released three in-house AI models — MAI-Transcribe-1 (speech recognition), MAI-Voice-1 (speech synthesis), and MAI-Image-2 (image generation) — available in public preview exclusively via Microsoft Foundry (formerly Azure AI Studio), signaling a direct push to reduce reliance on OpenAI and compete with Google in foundational model development. The move comes as Microsoft's own Terms of Service describe Copilot as 'entertainment only,' warning against relying on it for important advice — a contradiction with its $30/user/month enterprise pricing that is generating significant backlash from IT buyers. CEO Satya Nadella reportedly assumed direct control over AI product development in September 2025, and Forbes noted that Microsoft's agent development stack is confusing developers compared to simpler offerings from competitors.
