GPT-Transcribe / GPT-Live-Transcribe

Two speech-to-text models replacing Whisper and 4o-transcribe as the OpenAI API defaults: batch GPT-Transcribe ($0.0045/min) and streaming GPT-Live-Transcribe ($0.017/min). 57 languages; ~8.98% WER vs Whisper-1's 15.21%. Proprietary — a notable closed turn for the line that began with open-source Whisper.
