$0.00675 / minWhen to use Gemini 3.5 Transcribe
Where this model earns its cost — and where it doesn't.
Gemini 3.5 Transcribe is a speech-to-text model for recorded audio, not a chat model and not a live streaming session. On Kyma it is served through the same OpenAI-compatible transcription endpoint as the other STT SKUs: multipart `file` or JSON `audio_url`, response `{ text, language?, duration? }` with `json` or `text` — it does not return per-segment timestamps.
It accepts up to about an hour of audio per request. Billing is per minute of audio (one-minute minimum, rounded up), not per token. The `transcribe` alias is unchanged and still resolves to whisper-v3-turbo; this SKU is opt-in by id.
This is file transcription only. It does not answer questions about how the audio sounds, and it is not the live streaming companion.
Meeting and call transcripts
Turn recorded meetings and call logs into plain text for search and notes.
Multilingual dictation
Transcribe speech across many languages without swapping SKUs.
Captions from a file
Produce a transcript from an uploaded clip, then format it client-side.
Voice-agent offline pass
Batch-transcribe recorded user audio before a later language-model step.
Not ideal for: Do not use this for live bidirectional speech or for audio-scene questions (tone, music, SFX). Those are different endpoints. It returns a plain transcript with no per-segment timestamps: `verbose_json`, `srt` and `vtt` are refused on this SKU (`400 segments_unsupported`) — use whisper-v3-turbo for timestamps.
