Former Google China president Kai-Fu Lee says Chinese AI companies such as DeepSeek and Moonshot AI now pose a "significant challenge" to OpenAI and Anthropic, arguing that cheaper open-weight models sit about six months behind closed U.S. flagships and undercut them on price.

Cheaper Chinese AI, OpenAI's problem

DeepSeek and Moonshot now pose a significant challenge: open models trail U.S. flagships by about six months and sell at a fraction of the price. American labs still keep the profits.

Reach

Open models win the larger share

Developers mix stacks: Claude for plans, cheaper Chinese models for execution. Polsia cut monthly AI spend from $1 million to $100,000. Lindy cut spending 90% after moving to DeepSeek.

Limits

Quality still trails — and profit is unclear

U.S. labs still lead on most quality metrics. Users report weaker guardrails and stray Chinese characters. Chinese vendors face an 80% API discount and almost 1,000 rival models; some investors stay wary of Beijing's industrial agenda.

Lee's split verdict

Would you pay $50,000 for a new Tesla, or $15,000 for one that is six months old?

U.S. closed labs

iPhone model: high enterprise prices, more profit.

Chinese open labs

Android model: more share, users may pay nothing.

Likely outcome if the quality gap stays narrow.
