Mistral AI adds Deep Research agent, voice mode with Voxtral model to Le Chat

Mistral AI has released a major update to Le Chat, its AI assistant platform, adding research capabilities, voice input, and new organizational tools.

Deep Research Agent

The new Deep Research mode (in preview) functions as a tool-augmented agent that plans research queries, searches for information, and synthesizes findings into structured, reference-backed reports. According to Mistral AI, the agent can "break down" complex questions, gather credible sources, and produce reports with citations.

Voxtral Voice Model

Le Chat now supports voice input through a new model called Voxtral. The voice-in model is designed for "natural, low-latency speech recognition," allowing users to interact with the assistant through speech rather than text. Mistral AI claims the system can keep pace with natural speaking speeds.

Magistral Reasoning and Multilingual Support

The update includes a "Think mode" powered by Magistral, Mistral's reasoning model. According to the company, the model provides "clear, thoughtful answers" for complex questions and supports multilingual reasoning, including code-switching between languages within a single conversation. The company cites examples like drafting proposals in Spanish or clarifying legal concepts in Japanese.

Projects and Image Editing

Le Chat now includes Projects, a feature for organizing related conversations into folders with context retention. Each project maintains its own library and remembers tool settings.

The platform has also added image editing capabilities through a partnership with Black Forest Labs. Users can edit generated images with text prompts like "remove the object" or "place me in another city." Mistral AI claims the system preserves character and object consistency across edits.

Availability

All features are available in Le Chat at chat.mistral.ai and through mobile apps on iOS and Android. Mistral AI states no credit card is required to access the features. Pricing for the new capabilities was not disclosed.

What this means

Mistral AI is expanding Le Chat beyond basic conversational AI into research and multimodal territory, directly competing with features in ChatGPT, Claude, and Perplexity. The addition of Voxtral puts Mistral in the voice assistant space alongside OpenAI's Advanced Voice Mode and Google's Gemini Live. The Deep Research agent positions Le Chat as a potential alternative to Perplexity's research-focused interface, though comparative performance benchmarks are not yet available. The key question is whether Mistral's models can match the quality of established players in these specific use cases.
