Kimi K2 Thinking is now released and open-sourced!
Featuring a “model as agent” approach, it’s not only Kimi’s “most capable open-source thinking model to date,” but also masters the ability to think while using tools simultaneously—
Without human intervention, it can execute 200-300 consecutive tool calls.
