MBZUAI's IFM Ships K2 Horizon: Six Fully Open Models From 0.9B to 375B Parameters Under Apache 2.0

The Institute of Foundation Models at MBZUAI released K2 Horizon on Sept 3, a fleet of six Apache 2.0-licensed models sized 0.9B, 3.7B, 7B, 32B, 36B-A4B, and 375B-A23B — pitched as the largest fully open AI release in history, with weights, code, training data, and methodology all published. IFM claims the 0.9B, 3.7B, and 7B tiers hit SOTA at their scales on reasoning, math, coding, and agentic benchmarks. Models are day-zero supported by vLLM, SGLang, Ollama, and Unsloth.
