The release is real and the numbers in the caption are exact. IFM's own launch blog states that it is releasing K2 Horizon, a connected fleet of six models: 375B-A23B, 36B-A4B, 32B, 7B, 3.7B, and 0.9B . The corresponding Hugging Face repositories exist under the IFM organization, including K2-Horizon-375B-A23B, described as the flagship of the family, a sparse Mixture-of-Experts model that stores 375B parameters and runs 23B per token, with a 512K context window , plus 32B, MoVA-36B-A4B, 7B, 3.7B and 0.9B repos and GGUF conversions.

The licensing and distribution details check out. Models and code are released under Apache 2.0, and the API is live through inference partners including Compass, Cerebras, AWS, and Nebius . IFM states that the models and code are under Apache 2.0, while datasets retain their applicable licenses, including licenses such as ODC-BY .

The size-to-device positioning in the caption is taken almost verbatim from IFM. The 0.9B model targets highly constrained environments like watches and glasses; 3.7B and 7B bring advanced capabilities to phones and on-device apps; a dense 32B and sparse 36B-A4B cover local hosting and on-premise servers; and the 375B-A23B tops the fleet for demanding enterprise deployments.

The quote is authentic and the caption reproduces the operative sentence accurately. Per the press release, Hector Liu, director of IFM's Silicon Valley lab, said the institute is releasing an entire fleet at once, six models, from one small enough to run on a watch to a flagship built for enterprise reasoning , and that developers can start on the smallest model and scale to the flagship.

The one material gap is timing on "fully open." The blog frames the lifecycle release in present tense: IFM says it is releasing intermediate checkpoints, training data or detailed data-construction recipes, open architecture, mixture compositions, training code, configurations, fine-grained logs, evaluation results, and final weights . The model cards themselves are in future tense: the flagship card says intermediate checkpoints will be released, and that training data/recipe and the training code will be made public . Independent commentary flagged this directly, noting that IFM's launch materials describe the fleet as fully open and present the training lifecycle as part of the release, while the current Hugging Face card for the 375B flagship says the final checkpoint is available and that intermediate checkpoints, data, and training code will be released . Separately, one of the six is not shipped in final form: the 32B card describes K2-Horizon-32B-Stage1, notes that the final checkpoint is to be released, and states that results are for stage 1 of the final model training with stage 2 results out soon .
