Kimi K3 领先开源权重，阿里 Qwen3.8 Max 下周发布

Kimi K3 still leads open weights at 57, just one point ahead of the Qwen3.8 Max weights, that Alibaba plans to release next week.

Alibaba does win two comparisons that suggest where this goes next, taking GDPval-AA at 1739 Elo against Kimi K3's 1685 and holding a smaller footprint at 95B active parameters per pass.

Alibaba built that model to close the gap, spending 2.4T total parameters against Kimi K3's 2.8T and climbing 10 points over Qwen3.7 Max.

Kimi K3 runs a task for $0.86 while Qwen3.8 Max needs $1.14, because Alibaba's model takes more agentic turns and pushes its output token usage up 45% to 145M.

I would treat Kimi K3 and Qwen3.8 Max as tied on capability, then pick on the things that actually separate them, which is cost.
