The biggest AI story to start the week is the Trump administration's decision to place export controls on Anthropic's Fable 5 and Mythos 5 models, forcing Dario Amodei's frontier AI lab to restrict foreign access.

The move comes as Chinese open-source models have been rapidly closing the compute gap with U.S. labs. Anthropic's latest release appears to have widened that gap again, particularly in frontier reasoning, coding, and cybersecurity use cases.

Export controls could have second-order effects on the global AI race, according to analysts at Jefferies. By limiting access to Anthropic's most advanced models, Trump officials may slow the pace at which foreign developers, particularly in China, can study, benchmark, or distill these advanced frontier models into cheaper open-source systems.

"US models are improving at a faster pace, likely due to computational advantage, but anti- distillation and US export control are new negatives for China AI," the analysts wrote in a note on Sunday.

The key question now is whether Fable 5 and Mythos 5 include stronger anti-distillation safeguards to prevent Chinese labs from replicating or compressing Anthropic's advances into open-source models. If so, the export curbs may not just be about access. They may represent a broader effort to protect America's AI lead.

To understand the full AI model landscape, not just in the West but also in the East, Bank of America analysts, led by Alex Liu, penned an insightful note on Monday morning about leading Chinese models.

Liu wrote that China's AI model market is moving into a two-speed global structure, with U.S. labs likely to retain the lead in frontier capabilities while Chinese players gain share in lower-cost, high-volume use cases.

She noted that Chinese models are narrowing the gap through efficiency gains, architecture optimization, distillation, and lower-cost inference, making them increasingly affordable.

Liu said AI labs at Alibaba, ByteDance, Tencent, and Baidu are racing against independent labs, such as DeepSeek, Zhipu, MiniMax, and Moonshot AI.

Who's who in the China AI model market

Incumbents

• Major internet companies such as ByteDance, Baidu, Alibaba, and Tencent—many of which have established cloud businesses—have developed proprietary AI foundation models in-house.

Independent AI labs

• DeepSeek, MiniMax, Zhipu, and Moonshot AI are independent AI labs

China AI model landscape is intensely competitive

Liu's view is that China AI has shifted from a frontier story to an affordability story. But with the U.S. government now able to halt foreign access to advanced models, as it just did with Anthropic's Fable 5, it appears increasingly difficult for Chinese labs to copy, distill, or reverse-engineer U.S. frontier models.
