Strengths

  • Lower word-error rate than the legacy whisper-1 API
  • The default transcription model in OpenAI's API docs
  • Shares the modern GPT-4o API surface

Weaknesses

  • Hosted API only — not open weights (use Whisper large-v3 to self-host)
  • A newer gpt-4o-mini-transcribe snapshot (2025-12-15) reduces hallucinations further
