kimmonismus · x · 2026-09-03
The Institute of Foundation Models at MBZUAI released K2 Horizon: six models spanning 0.9B to 375B parameters, billed as the largest fully open-source model launch in AI history, with open training code, data recipes, checkpoints, logs and evals.
- Top-tier performance in coding and agentic tasks at every size class; the 0.9B, 3.7B and 7B models set new SOTA at their scales
- The 375B flagship is enterprise-ready, competing with leading open-weight models on coding and agentic work
- Commenters note that weights give the result while the full training record shows how they got there — what open releases should look like
