No free credits for new accounts since October 2025.\n\n## Before you call either\n\n### Mistral Voxtral Transcribe\n\n1. Send `model=voxtral-mini-latest` and one of `file`, `file_url` or `file_id` as multipart form fields to `/v1/audio/transcriptions`\n2. Leave `language` out when you ask for `timestamp_granularities`, the docs say the two are not compatible\n3. Use the batch endpoint for diarisation. `voxtral-mini-transcribe-realtime-2602` does not accept `diarize`\n4. Pin `voxtral-mini-2602` if output must not change, since `-latest` aliases can move\n5. Mint browser tokens with `POST /v1/client/sessions` close to connection time and pass them in `Sec-WebSocket-Protocol`, never the API key\n\n### Soniox Speech-to-Text\n\n1. Pass `audio_url` for public files and skip the upload step. Delete uploaded files or they count against the 10 GB quota for 30 days\n2. Use the `context` field for names and domain terms\n3. Buffer audio while the WebSocket connects, then flush it after the config message\n4. Split anything over 300 minutes. The cap is fixed\n5. Set `client_reference_id` so failed or duplicate requests can be traced in the usage log\n\n## Questions\n\n### Which is better for AI agents, Mistral Voxtral Transcribe or Soniox Speech-to-Text?\n\nMistral Voxtral Transcribe scores 64.1 (B) on agent readiness against Soniox Speech-to-Text's 58.2 (C), and leads in 5 of 7 scored categories.
