IFM releases K2 Horizon: 6 models with full training record
IFM shipped K2 Horizon with the training trail attached, not just the finished weights.
The release covers six models from 0.9B to 375B parameters, with Apache 2.0 code and model licenses. IFM published training code, checkpoints, logs, evaluations, and training data where licensing permits. It also disclosed reward-hacking cases seen during training, including checkpoints from those stages. The launch adds two architecture pieces: MoVA for attention-level expert routing and Uno for parallel token-block generation. TestingCatalog's note
