AI is happening. The future is updating.K2-Horizon-7B
K2-Horizon-7B is the medium dense member of the K2-Horizon family: a 7B-core decoder-only model with a 512K context window. - **Strong dense baseline.** A 7B-class dense model evaluated across agentic, coding, long-context, and reasoning benchmarks. - **512K context.** Native 524,288-token context from the midtraining stages onward. - **Diffusion Adapters.** For faster inference (HF). - **Intermediate checkpoints.** Intermediate checkpoints are released so capability changes can be studied across training rather than at a single checkpoint. - **Fully open.** Training data and recipe, training code, and evaluation resources are public. The chart at the top of this card shows K2-Horizon-7B against selected reference models. The table below lists every comparison model used in the figure.
