The bagel they save for the regulars. Don't skim, savour.
Summary
K2-Think is a 32B parameter reasoning system that achieves state-of-the-art performance, matching or surpassing much larger models like GPT-OSS 120B and DeepSeek v3.1. Built on Qwen2.5, it demonstrates that smaller models can compete at the highest levels through advanced post-training and test-time computation techniques. The system excels in mathematical reasoning with top scores on public benchmarks and strong performance in code and science domains, while offering fast inference speeds of over 2,000 tokens per second.
