Mistral just launched Mistral Medium 3.5, an open-weight 128B model powering new asynchronous cloud agents in Vibe and Le Chat. Instead of locking up your local terminal, agents now run across parallel cloud sandboxes and automatically open GitHub PRs when finished. It hits 77.6% on SWE-Bench Verified while fitting on as few as four GPUs.
Mistral AI just unveiled Forge, a platform that lets enterprises build frontier-grade AI models using their own internal codebases, policies, and operational data. It supports pre-training, post-training, and RL across both dense and MoE architectures. Crucially, it is built agent-first, allowing coding agents like Mistral Vibe to autonomously handle hyperparameter tuning and synthetic data generation.
Mistral AI just released Devstral 2, a lightweight open-weights coding model family led by a 123B flagship and a 24B small version. The larger model scores 72.2% on SWE-bench Verified at up to 7x the cost efficiency of Claude Sonnet, while the 24B version runs locally on consumer hardware. The release also includes Mistral Vibe, an open-source terminal CLI for autonomous software development.
