## AI 摘要

Mozilla 新报告称开源权重模型现在只比闭源前沿落后约四个月。Kimi K3 在 Terminal-Bench 上接近 Sol，GLM-5.2 以不到五分之一的价格逼近 Claude Opus 表现；OpenRouter 上按 token 量排名前十的最大模型中有八个是开源权重。闭源模型在最难任务上仍领先，但差距已明显缩小。

Open-weight AI models are now only around four months behind the closed frontier, according to a new Mozilla report!

Kimi K3 nearly matches Sol on Terminal-Bench, while GLM-5.2 approaches Claude Opus performance at less than one-fifth the cost. Eight of the ten largest models on OpenRouter by token volume are now open-weight.

Closed models still lead on the hardest tasks, but the gap has become surprisingly small.
