8:43How To Run Kimi K3 Agent OS For FREE
A five minute walkthrough of getting Kimi K3 running on a free kimi.com account, plus the three settings that decide how fast you burn the free allowance. The model dropdown defaults to K2.6, so the switch to standard K3 is the whole point; K3 Swarm sits right beside it and, on a free account, empties the allowance almost instantly, sometimes inside one task. Context window stays on standard because extra long is premium locked, and thinking effort stays on standard because max spends more tokens on every response. He reports that K3 beat Fable 5, GPT 5.6 and Opus 4.82 on his own private benchmark, and shows a 3D racing game build rerun on K3 with better structure, a score counter, a speed display and collectibles. Two limits close it out: free access can be paused or capped at peak times, and the July 2026 open source release will need serious hardware rather than a laptop. Worth knowing that the free part is Kimi K3 itself; Agent OS, the system he runs it inside, is his own paid product.
