With its open-weight LLMs, Mistral AI quickly grabbed attention. Now, Mistral AI is further expanding its capabilities by transforming Le Chat into a voice-enabled, research-grade AI assistant. With the addition of the Deep Research mode and the powerful Voxtral model for voice recognition, Le Chat is no longer just a chatbot. It is now a multilingual, agentic AI that is made for important jobs.
This blog post talks about how these new features work, how they stack up against competitors like OpenAI ChatGPT, Google Gemini, Claude by Anthropic, and Meta AI, and what these changes mean for end users, businesses, and the future of AI help.
What is Le Chat, the talking AI developed by Mistral AI?
Le Chat is Mistral AI’s most popular talking AI. Le Chat operates using Mistral AI’s own open-weight language models. Initially, Le Chat was designed solely for quick and simple text messages. Now, it’s grown into a voice-interactive and research-savvy tool.
With the July 2025 updates, it now features
Featured
- Voice recognition using Voxtral (ASR and TTS)
- Conversational speech mode with live transcription
- Agent-based Deep Research mode that generates structured reports with citations
- Project folders to organize conversations with memory and file uploads
Voxtral: Mistral’s Open Voice Recognition AI
Voice recognition AI has changed a lot with the new Voxtral model. Voxtral is open-source (Apache 2.0) and has models in both 24B and 3B sizes, unlike private ASR tools. English, French, Spanish, Hindi, and Arabic are just a few of the native languages that it serves.
Key Features of Voxtral in Le Chat:
- Real-time transcription of user speech
- Text-to-speech replies using synthetic voices
- Built-in summarization and Q&A on audio input
- Function-calling from speech (trigger workflows via voice)
- Low-latency, conversational flow
This positions Le Chat as not just a chatbot, but a fully voice-capable assistant—ideal for mobile users, accessibility, and hands-free productivity.
Deep Research Mode: How It Works
Mistral’s Deep Research tool allows Le Chat to behave like an autonomous research agent:
- Breaks down user queries into sub-questions
- Performs web searches and consults multiple sources
- Synthesizes structured reports with credible citations
- Displays findings with links and summaries
This tool-augmented approach transforms Le Chat into a capable analyst that can back up its answers—ideal for researchers, writers, students, and professionals.
