IFM AI introduced K2 Horizon, a connected fleet of six foundation models ranging from 0.9B to 375B parameters. The models deliver frontier performance on coding and agentic tasks, with the 0.9B, 3.7B, and 7B variants setting new SOTA at their scales. IFM calls it the largest fully open-source model launch ever, releasing all code, training data, and recipes, with stronger RL-trained checkpoints promised soon.
