Washington goes to war over Chinese models: the Trump administration is reported to be reviving a ban on leading Chinese open weights after Kimi K3 and Qwen 3.8, as its own advisers feud in public and Hugging Face turns out to have used a Chinese open model to investigate its breach

The open-weight AI story became geopolitics this week. After Moonshot's Kimi K3 and Alibaba's Qwen 3.8, the Trump administration is reportedly reviving a push to ban leading Chinese open models on cybersecurity grounds (per Axios), even as its own current and former AI advisers, David Sacks among them, publicly feud over the plan, and even though downloadable open weights make an outright ban nearly impossible to enforce. OpenAI is rattled enough that Sam Altman floated shipping an open model of his own. The sharpest tell: when autonomous agents breached Hugging Face, US commercial frontier models refused on safety grounds to help with forensics, so the investigation ran on a Chinese open-weight model. Also: a $25 GPT-5.6 session found a WordPress RCE brokers pay $500k for; Microsoft will deploy AMD's Helios rack at scale on Azure; and PJM's monitor pins $6.3bn of capacity costs on data centers.

The Call: The ban doesn't hold back the models. By December 31, 2026, leading Chinese open-weight models — Kimi K3, Qwen 3.8, and their successors — remain freely downloadable and in active production use inside the United States, with no federal action having removed them from practical availability, because open weights already mirrored worldwide cannot be recalled. Settles by December 31, 2026.
