Graham Neubig(@gneubig):This is amazing work! It's the first release of this scale from IFM so I expect rough edges when the models are actually used, but it's open source so if you don't like it you can fix it yourself! Great resource for studying training dynamics and interpretability as well.

Introducing K2 Horizon: a connected fleet of six foundation models ranging from 0.9 billion to 375 billion parameters. - Frontier performance: Across coding and agentic tasks, K2 Horizon delivers top-tier performance in every size class—with the 0.9B, 3.7B and 7B models setting new state of the art at their respective scales. - Radical openness: K2 Horizon represents the largest fully open-source model launch in AI history. The fully open code, training data and recipes are a significant step forward in transparency. Launch page: Tech blog: Hugging Face:
