Moonshot AI has released Kimi K2 Thinking, an open-source “Thinking Model” designed to autonomously execute complex tasks. Employing a “Model as Agent” approach, Kimi K2 Thinking can perform 200-300 consecutive tool calls to solve multifaceted problems. The model demonstrated its capabilities on industry benchmarks, achieving scores of 44.9% on HLE, 60.2% on BrowseComp, and 71.3% on SWE-Bench Verified.

Kimi K2 Thinking showcases strong reasoning, programming (including HTML and React), and intelligent search skills, allowing it to convert concepts into working products. While its writing abilities have been improved, creative writing specifically was not a primary focus of testing. The model boasts a total of 1 trillion parameters, with 32 billion active during operation, and supports INT4 quantization for faster inference. It’s accessible through kimi.com, the Kimi App, and via the Kimi Open Platform API.

A Reddit user, /u/zshm, noted that computational limitations might occasionally result in “insufficient computing power” messages. The original discussion can be found on Reddit.
