Mistral Unveils Voxtral: Open-Source Audio AI for Businesses

French AI startup Mistral has launched Voxtral, an open-source family of AI audio models for businesses. Voxtral offers production-ready speech intelligence for transcription, comprehension, and action-oriented interactions, with multilingual support and cost-effective deployment options, aiming to challenge closed, expensive alternatives.
Key Takeaways
- Voxtral is Mistral’s first open-source audio model family for businesses.
- Offers transcription, understanding, and voice-activated actions.
- Two main variants: Small (24B parameters) and Mini (3B parameters).
- Multilingual support across nine languages and 30–40 minute audio windows.

An Open-Source Solution For Speech Intelligence
As speech becomes the default way to interact with machines, Mistral aims to bridge the gap between basic open systems and costly proprietary offerings. Voxtral leverages an LLM backbone (Mistral Small 3.1) to deliver end-to-end speech processing, including:
- Accurate transcription of up to 30 minutes of audio.
- Deep understanding of up to 40 minutes of content, enabling queries and summaries.

By publishing open weights, Mistral empowers businesses to maintain control over deployment, infrastructure, and costs without sacrificing performance.
