Mistral AI Launches Voxtral 3 Real-Time Voice Agent Stack Starting at $0.0035 Per Minute

Mistral AI has launched Voxtral 3, a new family of language models and developer tools built for real-time voice agents, with transcription pricing starting at $0.0035 per minute. The stack combines a speech-to-text model (Voxtral Small Transcribe 3), a text-to-speech model (Voxtral Mini TTS 3), and a LiveKit-based voice agent SDK into a single streaming pipeline for listening, reasoning, tool execution, and speaking. Transcription supports more than 50 languages, while text-to-speech output covers over 35 languages and 50 dialects with emotional adaptation. Agents built on the system can connect to external systems during live conversations to complete operational tasks such as checking invoices or booking appointments. Mistral states that organizations can deploy the system on their own infrastructure or via EU-hosted APIs to maintain control over their data.
