  • Claude Opus 5.565 days after its cutoff
  • Gemini 4 Hydrogen156 days after its cutoff
  • Grok 4.795 days after its cutoff

None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 65 days before it.

Key facts

  • Released 2026-09-03; public preview in Azure Speech (Fast Transcription API, enhancedMode model MAI-Transcribe-2)
  • 60 languages (up from 43 in MAI-Transcribe-1.5); code-switching, automatic language ID

What happened

Three months after MAI-Transcribe-1.5 debuted at Build, Microsoft AI shipped its second-generation transcription model, adding diarization and timestamps and expanding to 60 languages. It is available in Microsoft Foundry / Azure Speech, the MAI Playground and OpenRouter (microsoft/mai-transcribe-2), and can also transcribe input audio in Azure Voice Live.

Why it matters

Speech-to-text prices collapsed in September 2026: MAI-Transcribe-2 ($0.10/hr promo), Grok Voice Transcribe 2.0 ($0.10/hr batch, 2026-09-18) and Meta’s Muse Voice Transcribe ($0.18/hr, 2026-09-03) all undercut OpenAI’s GPT-Transcribe ($0.27/hr) and whisper-1 ($0.36/hr). Accuracy and speed claims are Microsoft’s own.
