K1 is a model that underwent post-training using datasets such as iannicity/KIMI-K2.5-1000000x, iannicity/Hunter-Alpha-SFT, and stepfun-ai/Step-3.5-Flash-SFT.
It subsequently incorporated GRPO-based reinforcement learning training derived from Chinese logical problems, resulting in relatively consistent reasoning capabilities and enhanced cognition in complex scenarios.
I have also observed that GRPO produces side effects such as improved numerical computation ability, which is related to its influence on layers such as MLP.
