K2 Think

At just 32 billion parameters, it delivers performance on par with flagship reasoning models like OpenAI and DeepSeek — systems built on hundreds of billions of parameters. This breakthrough makes K2 Think the world’s most parameter efficient advanced reasoning model, redefining what is possible with compact architectures. K2 Think ranks among the industry’s top reasoning systems, delivering top scores for top math performance across benchmarks such as AIME ’24/’25, HMMT ’25, and OMNI-Math-HARD.
