Mistral Medium 3.5 ships open-weight 128B with remote coding agents and Le Chat Work Mode

Mistral released Medium 3.5, a 128B-parameter dense model unifying instruction-following, reasoning and coding under a modified MIT license, self-hostable on as few as four GPUs. It powers new remote coding agents in Mistral Vibe (running asynchronously in the cloud) and a Work Mode in Le Chat for multi-step workflows across connected tools. The model is live on NVIDIA NIM and Hugging Face.
