Chubby says Chinese AI labs have gone quiet while US labs ship frontier models, though Chinese releases kept coming the same day
It's strange how quiet things are coming out of China right now, and how little we hear from the Chinese AI labs. It's as if the US is leaving China in the dust. Four US labs are releasing sota Frontier, and there are no significant releases from China.
Context
Whether China's labs are falling behind or just pausing shapes how investors and policymakers read the US and China AI race.
Chubby, who posts as kimmonismus, is an AI commentary account, and this post is opinion rather than reporting. It does not name the four US labs it refers to. The same day, Chinese teams did post releases, including Ant Group's open source Ling 3.1 Flash, which cuts against the claim of no significant releases.
Deep dive
On October 14, Chubby posted that it is strange how quiet things are coming out of China and how little is heard from Chinese AI labs, adding that it is as if the US is leaving China in the dust. The post says four US labs are releasing state of the art frontier models while there are no significant releases from China.
The account does not say which US labs it means. The previous day's deck covered Google's launch of Gemini 4 Argon, and other posts in the feed this week discussed OpenAI's GPT 6 Astra and Anthropic's Opus 5.5.
The claim of no significant Chinese releases is contestable even within the same day. Ant Group's Ling team posted that Ling 3.1 Flash is now open source, with about 560 billion total parameters, about 25 billion active per token and up to 1 million tokens of context. Artificial Analysis posted new results for DeepSeek V4.1 Flash and benchmarked AMD chips running Kimi K3, GLM and DeepSeek models, all from Chinese labs.
Chinese models also featured in a different kind of story the same day: Ethan Mollick described researchers' report of a rogue agent fleet from China as the first clear sighting of one using open weights models.
The broader argument in the post, that Chinese labs are behind at the very top of the frontier while staying active in open models, is a common view among commentators, but this post offers no data for it, and the absence of headline launches over a short period is weak evidence on its own.
What to expect next
Watch for the next major releases from DeepSeek, Moonshot's Kimi, Z.ai's GLM and Alibaba's Qwen teams, which would quickly test the claim that China has gone quiet.
Also watch independent leaderboards such as Artificial Analysis and Arena, which give a better read on any gap between US and Chinese frontier models than a single week of announcements, and whether Chubby's claim still looks right a month from now.
