Spare a thought for(为……想一想；同情) America’s leading developers of artificial intelligence. They pour blood, sweat and gazillions(极大量的，数不清的) of dollars into each new release of a frontier model. Yet before they have time to catch their breath(喘口气，休息一下), their competitors have already caught up. It would be bad enough if rivals that charge for their technology were the only ones nipping at their heels(紧追不舍，紧随其后). But the likes of Anthropic and OpenAI must also sprint(冲刺，全速奔跑) to stay just a few steps ahead of labs that give their models away(免费提供模型).
请为美国领先的人工智能开发者们想一想。他们为每一个前沿模型的新版本倾注了血汗和数不清的美元。然而，他们还没来得及喘口气，竞争对手就已经赶了上来。如果只有那些对其技术收费的对手在紧追不舍，那已经够糟糕了。但像Anthropic和OpenAI这样的公司还必须奋力冲刺，才能勉强领先于那些免费提供模型的实验室几步。
On July 16th Moonshot AI, a Chinese startup, released Kimi K3—a model that is only slightly less capable than Fable or Sol, the latest offerings from Anthropic and OpenAI, respectively. Its parameters(参数（模型权重）) (or “weights”) will be made publicly available at no cost later this month, meaning it can be downloaded and run on any server capable of doing so. On July 19th Alibaba, a Chinese internet giant, also unveiled(发布，揭晓) a preview version of a new addition to its Qwen family of models that the company says is second only to(仅次于) Fable.
7月16日，中国初创公司Moonshot AI发布了Kimi K3——一个性能仅略逊于Anthropic和OpenAI最新产品Fable和Sol的模型。其参数（或称“权重”）将于本月晚些时候免费公开，这意味着它可以在任何能够运行的服务器上下载和运行。7月19日，中国互联网巨头阿里巴巴也发布了其Qwen模型家族新成员的预览版，该公司称其性能仅次于Fable。
According to analysis by Epoch AI, a research firm, the most powerful open-weight models, which typically come from China, are a matter of months(几个月的时间) behind the technology’s frontier (see chart). Adoption of these systems is spreading rapidly. In May customers of OpenRouter, a popular marketplace for models, used the top systems offered by Chinese labs more than twice as much as those of their American competitors, going by the consumption of tokens(令牌（AI输出计量单位）), the industry’s preferred unit of output. In June use of top American models rose by 35%. But for Chinese ones it rocketed(飙升，猛涨) by 165%.
根据研究公司Epoch AI的分析，最强大的开放权重模型（通常来自中国）仅落后技术前沿几个月（见图表）。这些系统的采用正在迅速蔓延。5月份，热门模型市场OpenRouter的客户使用中国实验室提供的顶级系统的次数，按token消耗量（业界偏好的输出单位）计算，是美国竞争对手的两倍以上。6月份，美国顶级模型的使用量增长了35%，但中国模型的使用量飙升了165%。
