Summary
Mistral AI unveils Mistral Medium 3.5, a 128B dense model with a 256k context window designed for instruction-following, reasoning, and coding, released as open weights under a modified MIT license. It enables Mistral Vibe remote coding agents that run in the cloud (in parallel) and Work mode in Le Chat for multi-step tasks, extending the running context beyond the local machine.
