Summary

Mistral has released Mistral Medium 3.5, a new 128B dense model available in public preview, designed for instruction-following, reasoning, and coding tasks. This model features a 256k context window and can be self-hosted on as few as four GPUs. It achieves a 77.6% score on SWE-Bench Verified and 91.4 on τ³-Telecom. Concurrently, Mistral Vibe introduces remote coding agents that run in the cloud, allowing parallel execution and notifications upon completion, accessible via CLI or Le Chat. Additionally, a new "Work mode" in Le Chat, powered by Mistral Medium 3.5, offers an agent for complex, multi-step tasks like research, analysis, and cross-tool actions, with persistent sessions and visible tool calls.

Key takeaway

For AI Architects and NLP Engineers evaluating large language models for agentic workflows, Mistral Medium 3.5 offers a powerful, self-hostable 128B model with strong coding and reasoning capabilities. Your teams can leverage its remote coding agents for asynchronous development tasks and the new Work mode in Le Chat for complex, multi-step projects, potentially streamlining development cycles and enhancing productivity.

Key insights

Mistral's new 128B model and cloud agents enable parallel, long-horizon coding and complex multi-step tasks.

Principles

• Merge instruction, reasoning, and coding into one model.
• Enable configurable reasoning effort per request.
• Isolate coding sessions in sandboxed environments.

Method

Remote coding agents run in the cloud, allowing parallel execution and offloading tasks from local machines. Work mode in Le Chat uses an agent to orchestrate multi-step tasks, calling tools in parallel and providing visible actions.

In practice

• Self-host Mistral Medium 3.5 on four GPUs.
• Launch cloud coding agents from CLI or Le Chat.
• Use Work mode for cross-tool workflows and research.
