Voxtral Small 2507

by Mistral

Voxtral Small 2507 is Mistral's audio-native instruct model, combining a 24B model for audio understanding with robust text processing inherited from Mistral Small 3.1. It is designed for multi-turn chat and agentic workflows, accepting both audio and text inputs for flexible, speech-driven applications. The model handles audio-to-text workflows within a 32k token context window, processing audio up to 30 minutes for transcription or 40 minutes for understanding, Q&A, and summarization without external ASR systems. Function calling directly from speech lets voice commands trigger backend APIs and workflows, unlocking voice-first agent architectures. With native multilingual support and automatic language detection across major languages including English, Spanish, French, Portuguese, Hindi, German, Dutch, and Italian, Voxtral Small works globally. Released under Apache 2.0, it is available both as an open-weight download and via API.
