On Friday, the Chinese startup Moonshot AI unveiled Kimi K3, touted as the world’s largest open AI model with a staggering 2.8 trillion parameters. This launch positions Kimi K3 as a formidable competitor to existing systems from industry leaders like Anthropic and OpenAI, declaring it part of a "new frontier of intelligence."
Moonshot’s Kimi K3 allows developers to download, modify, and run the AI, differentiating it from proprietary models such as OpenAI's ChatGPT and Anthropic's Claude, which keep their systems confidential. While Moonshot acknowledges that Kimi K3 currently performs below Anthropic’s Claude Fable 5 and OpenAI’s GPT 5.6 Sol, the startup asserts that it still achieves “frontier-level” performance and surpasses several earlier models, including previous versions of GPT, Claude, and SpaceXAI’s Grok. In various benchmarks focused on coding and general tasks, Kimi K3 was found to be competitively effective in comparison to Fable 5 and significantly outperformed Claude Opus 4.8, Sol, and GPT 5.5, according to the company’s assessment. Analysts from Bank of America praised Moonshot’s advancements, noting that despite a restricted access to cutting-edge chips, the startup has made significant strides in model training and design.
In the wake of this announcement, shares of Moonshot's Chinese rivals faced a sharp decline, with Zhipu and MiniMax dropping 28.4% and 15.6%, respectively, in trading on the Hong Kong exchange. Z.ai, which launched a new model in June, experienced a similar 28.4% dip.
Founded in 2023, Moonshot AI has quickly emerged as one of China’s leading AI developers with support from major tech players like Alibaba and Tencent. Recent funding raised approximately $2 billion, boosting its valuation to over $20 billion, after a significant increase from its earlier valuation of $4.3 billion following a $500 million funding round last year. Moonshot reported that its annual recurring revenue has exceeded $200 million, driven largely by subscriptions for Kimi K3 and other AI offerings.
The backdrop to this rapid development is a landscape in which Chinese AI firms face constraints due to U.S. export controls on advanced AI chips, including Nvidia's H200 series. Recent developments suggest that the U.S. has initiated limited exports of these chips, although much discretion remains with the Commerce Department, which continues to regulate approvals stringently. Accusations have arisen alleging that some Chinese companies are attempting to smuggle restricted AI chips into China, while others are navigating the restrictions by securing computing power and purchasing processors through foreign subsidiaries.
