IFM releases six fully open K2 Horizon models

The Institute of Foundation Models released six fully open K2 Horizon models spanning 0.9B to 375B parameters, including weights, code, training data, and methodologies, according to its launch announcement. The fleet is available through Hugging Face, and IFM claims roughly 3× faster responses from diffusion distillation; that performance claim is vendor-reported. Operators should file the release as a reproducibility option—not an automatic production switch—and compare its smallest local model and 375B flagship against serving, license, and safety costs, as Qwen’s open-model ecosystem analysis recommends.
