Kimi K3 and the new frontline of AI competition

AI startup Kimi released its K3 model on Tuesday Beijing time, with third-party evaluations showing performance comparable to Claude 5 at a fraction of the cost per task.

Where is the debate heading, and what could it mean for future AI development and China-US AI dialogue?
