GPT-4o Mini Transcribe is a speech-to-text model powered by GPT-4o mini, offering improvements to word error rate and better language recognition and accuracy compared with the original Whisper models.
- It is the cost-effective option in OpenAI's transcription lineup, priced at half of GPT-4o Transcribe's audio-input rate, with a 16K-token context window and up to 2K output tokens per request.
- It suits high-volume transcription pipelines where accuracy still matters.
- Synthorai handles it through the OpenAI-compatible audio transcription endpoint.
