- Moonshot AI unveiled its new model, Kimi K3, on Friday, claiming it is the world’s largest open-source AI system with 2.8 trillion parameters.
- Alibaba followed with the unveiling of Qwen3.8 over the weekend, which it claims is one of the most powerful models available today.
- Release timelines indicate that Moonshot will release full model weights on July 27th, while Alibaba states that Qwen3.8 is “going open-weight soon.”
- These releases intensify the US–China AI race, suggesting that America’s lead in AI technology is narrowing.
- The impact of DeepSeek’s low-cost model last year is echoed in the recent releases, indicating a shift in the competitive landscape.
- Both Moonshot and Alibaba are emphasizing openness by making their advanced models publicly available, contrasting with the practices of leading US labs.
Moonshot AI has unveiled Kimi K3, the world's largest open-source AI model, featuring 2.8 trillion parameters. This launch, alongside Alibaba's Qwen3.8, marks a significant escalation in the competition between Chinese and American AI firms, as both companies aim to challenge the dominance of OpenAI and Anthropic.12347
Moonshot claims that its model consistently outperforms nearly all US systems, only falling short of OpenAI's GPT-5.6 Sol and Anthropic's Claude Fable 5. The company plans to release full model weights on July 27th, further enhancing accessibility and transparency in AI development.
Alibaba's Qwen3.8 is also set to go open-weight soon, emphasizing a shift towards public availability of advanced AI models, contrasting with the closed-door policies of leading US labs. This trend is expected to intensify the technological rivalry between the US and China, influencing both economic and national security policies.

The recent developments have shaken the industry, reminiscent of the impact of DeepSeek's low-cost model last year, which similarly challenged US systems. Analysts suggest that the competition is not new but highlights the narrowing lead of the US in AI technology.6
As the landscape evolves, the focus on open-source alternatives and cost competition may reshape the market dynamics, prompting a reevaluation of the value chain in AI.
“Kimi K3, with 2.8 trillion parameters, is set to release full model weights on July 27th, while Alibaba's Qwen3.8 claims to be 'second only to Fable 5' and 'one of the most powerful model[s] available today.' These releases sharpen the US-China AI race, echoing DeepSeek's impact last year and suggesting America's lead is narrowing.”
