Training on audio is the default and the opt-out is a per-request flag.\n\n**OpenAI Speech to Text.** `gpt-transcribe` costs $0.0045 an audio minute, and the audio endpoints keep no abuse-monitoring logs or application state. Speaker labels, timestamps, subtitles and translation exist only on `whisper-1` and `gpt-4o-transcribe-diarize`, which shut down on 26 February 2027 with no named replacement for those functions.\n\n## Before you call either\n\n### Deepgram Speech-to-Text (Nova-3, Flux)\n\n1. Add `mip_opt_out=true` to every request that carries customer audio\n2. Use Flux (`flux-general-en`) on `/v2/listen` for live agents and Nova-3 for files\n3. Back off exponentially on 429. The concurrency limit is per project\n4. Pass `callback` for long files so the request doesn't hit the 10-minute processing timeout\n5. Mint keys with an expiry for short-lived jobs\n\n### OpenAI Speech to Text\n\n1. Send `gpt-transcribe` to `POST /v1/audio/transcriptions` for recorded files. Use `languages` (a list), not `language`, and never send both.\n2. Keep each upload at 25 MB or less. Split longer audio between sentences and pass the previous chunk's text in `prompt`.\n3. For speaker labels send `gpt-4o-transcribe-diarize` with `response_format=diarized_json` and `chunking_strategy=auto` for audio over 30 seconds. Plan for its shutdown on 26 February 2027.\n4. Word timestamps, `srt`, `vtt` and `/v1/audio/translations` need `whisper-1`, which cannot stream and shuts down on the same date.\n5. On 429 or 503 wait at least `Retry-After` when present, then back off with jitter. Do not retry `credit_balance_exhausted` or spend-limit errors.\n\n## Questions\n\n### Which is better for AI agents, Deepgram Speech-to-Text (Nova-3, Flux) or OpenAI Speech to Text?\n\nOpenAI Speech to Text scores 72.4 (BB) on agent readiness against Deepgram Speech-to-Text (Nova-3, Flux)'s 70.3 (BB), and leads in 3 of 7 scored categories.
