China’s leading AI companies are adding to the pressure on Silicon Valley, as Moonshot and Alibaba unveiled models they say can match the advances of OpenAI and Anthropic at a fraction of the cost. The rapid-fire release suggests that America’s lead on the AI frontier is strengthening, even as the technology becomes central to national security, economic power, and national influence.
The opening salvo came from Beijing-based Moonshot AI, one of China’s leading AI model developers, which launched the Kimi K3 on Friday. Moonshot says its testing consistently ranks it above all US systems, trailing only OpenAI’s GPT-5.6 Sol and Anthropic’s Claude Fable 5, though it has come out on top in some benchmarks.
Over the weekend, Chinese behemoth Alibaba followed up with a preview of the Qwen3.8, a new model it says is ‘one of the most powerful models.[s] available today” and “second only to the Fable 5,” Anthropic’s flagship model.
Both companies emphasize a key difference in leading US labs: instead of locking their most advanced models behind closed doors, they make them publicly available. While other US companies, notably Meta, have taken a similar approach, releasing models that developers can freely download, modify, and build upon has become a growing area of differentiation for China’s AI industry.
Moonshot describes Kimi K3 as the world’s largest open-source AI system, with 2.8 trillion parameters. Parameter statistics are measures of the complexity of the model during training and give a rough indication of its scale and performance, although bigger does not always mean better. Alibaba says Qwen3.8 is a 2.4 trillion parameter model and is “continually evolving.” Neither OpenAI nor Anthropic discloses exact parameter calculations for their leading systems.
It remains difficult to assess how powerful the Chinese model is until it is fully released and independently tested. Moonshot says it will release the full model weights — the internal numbers learned during the AI model’s training — a week from now on July 27. Alibaba says Qwen3.8 will “go well soon.”
Still, the rollout has already sharpened the rivalry between the US and China in what has often been seen as the defining technology race of our time. They have shaken up the industry in an unprecedented way since DeepSeek launched a cheap model last year that rivaled the best US systems. The models also raise questions about whether the huge sums US companies are pouring into chips, data centers, and model training can secure long-term profits, especially if Chinese rivals can approach — or surpass — that threshold with fewer resources.
The prospect of two of China’s most capable models being released for others to download and adapt is in stark contrast to the highly-regarded approach of US labs, whose most advanced systems remain proprietary. That opening comes as Washington moves quickly to limit global access to basic technology. The government has used export controls to limit China’s access to the most advanced chips, as well as forcing Anthropic to take its most efficient system off the market over concerns it could help foreign rivals compete.
Whether the new Chinese models live up to their creators’ claims remains to be seen. But, like DeepSeek before them, they are likely to sharpen the technological rivalry between the US and China, influence economic and national security policy, and show that America’s lead is much smaller than it once appeared.
