A million tokens, measured in

Speech & audio

Spoken language runs ~150 words a minute, so a million tokens transcribes about 83 hours of talking β€” a hundred podcast episodes or three and a half days of speech.

Audio reaches the model as transcribed text, so the token cost of speech is really the token cost of words spoken at roughly 150 per minute. Podcasts, call center recordings, and meeting transcripts all follow the same math. For teams building transcription and summarization pipelines, knowing that 83 hours of speech fits in a million tokens helps scope both the compute and the budget.
