Remote agents in Vibe. Powered by Mistral Medium 3.5.

Summary

Mistral has moved coding agents to the cloud, enabling parallel, asynchronous task execution via Mistral Medium 3.5—a new 128B open-weight model optimized for long-horizon coding and productivity work. The update introduces remote agents in Mistral Vibe and Le Chat, along with a new Work mode for multi-step tasks like research and cross-tool workflows, all while maintaining human oversight for sensitive actions. Available today on Pro, Team, and Enterprise plans, Mistral Medium 3.5 is priced at $1.5 per million input tokens and $7.5 per million output tokens.

Coding agents have mostly lived on your laptop. Today we're moving them to the cloud, where they run on their own, in parallel, and notify you when they're done. You can start them from the Mistral Vibe CLI or directly in Le Chat, offloading a coding task without leaving the conversation. 

Powering this is Mistral Medium 3.5 in public preview, our new default model in Mistral Vibe and Le Chat, built to run for long stretches on coding and productivity work. The new Work mode in Le Chat (Preview) extends this with a powerful agent for complex, multi-step tasks like research, analysis, and cross-tool actions.

Highlights.

1. Mistral Medium 3.5, a new flagship model that merges instruction-following, reasoning, and coding into a single 128B dense model. Released as open weights, under a modified MIT license.

2. Strong real-world performance at a size that runs self-hosted on as few as four GPUs.

3. Mistral Vibe remote agents for async coding: sessions run in the cloud, can be spawned from the CLI or Le Chat, and a local CLI session can be teleported up to the cloud.

4. Start Mistral Vibe coding tasks in Le Chat. Sessions run on the same remote runtime and keep going while you step away.

5. Work mode in Le Chat runs on a new agent, powered by Mistral Medium 3.5, that works through multi-step tasks, calling tools in parallel until the job is done.
