The [release](https://mistral.ai/news/vibe-remote-agents-mistral-medium-3-5/) describes a 128-billion-parameter dense model in public preview, with downloadable weights under a modified MIT license. The same announcement introduces cloud coding sessions that can continue asynchronously and be started from the command line or Le Chat. ## A task can outlive the laptop session Mistral says remote sessions expose progress, tool calls, and file diffs, and can return work through a pull request. It also describes moving an ongoing local session into the remote runtime. Medium 3.5 combines instruction following, reasoning, and coding, and becomes the default model in the announced Vibe and Le Chat experiences. Evaluate model behavior and remote execution together: a useful coding result must satisfy the task while surviving the handoff into a different environment. Compare the resulting changes, available tools, and recovery behavior on the same bounded task. ## Review the execution boundary Our analysis: asynchronous coding changes where credentials, repository contents, and network access are exercised. Before delegating a repository, teams should define the task’s permitted scope, available secrets, and acceptable external actions. A remote sandbox is an execution boundary whose configuration needs inspection, not a substitute for deciding what the agent may do. The review artifact should include the final diff, tests actually run, unresolved failures, and any changes outside the requested area. Concurrent sessions also need an integration plan when they touch shared interfaces. For a first deployment, select a bounded maintenance task with an observable result and keep merge authority separate from code generation. Compare reviewer effort and accepted changes, not just the number of agent sessions launched. ## Source references -
