rupspace · x · 2026-09-03
IFM AI launched K2 Horizon, a family of six open-weight models from 0.9B to 375B, billed as the largest fully open-source model release ever — code, training data, and recipes all public. The flagship 375B targets reasoning and agentic work with a native 512K context, matching open MoE models up to 2.6x its size on tool use, terminal, and long-horizon tasks. Smaller models set SOTA at their scales (0.9B runs on a watch, 7B on a phone), and SGLang offers Day-0 support.
