Built on LiveKit, the SDK runs transcription, reasoning with tool calls, and speech in one streaming pipeline, and Mistral says each turn completes in under a second. Transcription covers 50+ languages, and the voice agent API starts at $0.04/min with Mistral Small 4. If you're building phone or support agents, note that it runs on Mistral's EU, US, and global endpoints or self-hosted.
