K2 Horizon 7B

K2-Horizon 7B is a 7B-core dense, decoder-only text-generation model from the K2-Horizon family, available under the apache-2.0 license with safetensors format and transformers library support. It has a 512K (524,288-token) native context window from midtraining onward, supports English, and was trained on IFM/K2-Horizon-Pretrain-Data and IFM/K2-Horizon-Midtrain-Data. The model card highlights strong dense-baseline performance across agentic, coding, long-context, and reasoning benchmarks according to the supplied chart/table, diffusion adapters referenced on Hugging Face for faster inference, released intermediate checkpoints, and public training data, recipe, code, and evaluation resources.

K2 Horizon MoVA 36B A4B

K2-Horizon-MoVA-36B-A4B is the sparse member of the K2-Horizon family, a Mixture-of-Experts model with Mixture-of-Values attention (MoVA). It stores 36B parameters and runs 4B parameters per token. The final checkpoint has been released; intermediate checkpoints, training data, recipe, and training code are stated as forthcoming. It supports text generation, is licensed under Apache-2.0, and has a native 524,288-token context from midtraining stages onward. The model card claims frontier-class results at 4B active parameters on agentic and reasoning benchmarks, and competitive performance against closed frontier models, but these claims are descriptions from the source rather than independently verified here.
