  • Claude Opus 5.528 days after its cutoff
  • Gemini 4 Hydrogen119 days after its cutoff

None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 28 days before it.

Key facts

  • gpt-transcribe: $0.0045/min, 25% cheaper than whisper-1 / gpt-4o-transcribe ($0.006/min)
  • Artificial Analysis WER 3.31% for gpt-transcribe, ~0.7 points better than gpt-4o-transcribe but behind ElevenLabs, Google and Mistral (The Decoder)
  • OpenAI-reported Common Voice (22 languages) WER: 40.37% whisper-1 vs 19.27% gpt-transcribe (press)
  • Deprecation announced 2026-08-26; shutdown 2027-02-26 for whisper-1, gpt-4o-transcribe, gpt-4o-mini-transcribe, gpt-4o-transcribe-diarize

What happened

OpenAI replaced its whole speech-to-text lineup with a file model and a streaming model under the new “GPT Transcribe” name, then scheduled Whisper’s API retirement. The open-source Whisper weights remain available.

Why it matters

Speech-to-text became a price war (OpenAI $0.0045/min vs Google Gemini 3.5 Transcribe, launched a month later) in which OpenAI is no longer the accuracy leader on independent WER benchmarks.
