K2 Horizon lineup is out on AA, and once again AA plots are misleading.

The K2 Horizon lineup has been released on Artificial Analysis, but its plots are considered misleading. The K2 Horizon 36B A4B model is noted as potentially useful for systems with 16GB VRAM and 32GB host RAM, though Qwen3.8-27B is suggested as superior for 24GB VRAM due to better speed, intelligence, and 256k context. For VRAM-poor users seeking 256k context, Ornith-1.5 or Nex-N2.5-mini are recommended. The K2 Horizon 3.7B might suit 12GB phones, but MiniCPM5-2B is expected to offer a better user experience.

This report directly compares K2 Horizon models against alternatives like Qwen3.8-27B, Ornith-1.5, and MiniCPM5-2B, offering specific hardware recommendations unlike general performance reviews.
