US lead in AI over China narrows after DeepSeek gains, BI says
That improving performance spells further market share gains for Chinese contenders
[BENGALURU] US artificial intelligence companies’ performance lead over China narrowed sharply in past months to a record low after labs such as DeepSeek gained ground, threatening US tech supremacy, according to Bloomberg Intelligence.
Top Chinese models lag their US rivals by just 3 per cent on benchmark scores after the September release of DeepSeek’s V4.1 Flash, Bloomberg Intelligence senior analyst Robert Lea wrote in a report on Monday (Oct 5).
That is down from about 9 per cent in May and 15 per cent earlier in 2026.
That improving performance spells further market share gains for Chinese contenders, he said.
China’s ascent is a result of deepening AI expertise and its researchers’ ability to optimise their models for domestic hardware.
The gains raise questions about the usefulness of US export restrictions on technology such as Nvidia chips, intended to curtail Chinese AI advances and prevent the likes of Huawei Technologies from making progress with their own alternatives.
The Asian country’s progress “casts further doubt on the long-term sustainability of US technological supremacy in AI”, Lea said.
The two superpowers are vying to dominate a technology that drives economic productivity, military leadership and global influence.
China’s lower-cost AI models are bridging the gap with US rivals in user numbers just as Anthropic and OpenAI chase trillion-dollar valuations in stock market debuts, touting their superior capabilities.
DeepSeek’s V4.1 Flash ranked sixth globally in September on LiveBench, making it the highest-ranked Chinese model since the startup broke ground with its reasoning model R1 in 2025.
LiveBench scores AI models based on their responses to and analysis of questions, puzzles or tasks, a process akin to gauging human IQ.
DeepSeek last recorded a LiveBench score of 81.1, below Anthropic’s best score of 83.4.
That means the DeepSeek model delivers “comparable performance” to leading AI systems from Anthropic and OpenAI, Lea said.
Still, while the score gap has narrowed to just 3 per cent, just three of the top 15 models as assessed by LiveBench were Chinese.
Such rankings shift, Lea cautioned, and it could be difficult to monetise regardless of leaderboard scores.
Chinese models face increasing US regulatory scrutiny and even potential bans following allegations of model distillation.
The Chinese AI industry could remain unprofitable until 2030, Lea said.
A focus on low-margin token supply and a brutal price war may make it impossible for any firm to gain a competitive edge in a domestic market flooded with more than 1,100 large language models.
ByteDance’s Doubao is the frontrunner in AI app monetisation, while the chatbots of rivals DeepSeek and Tencent Holdings remain free, Lea said.
“Putting China’s AI sector on a sustainable profit footing will require a cooling of competitive pressures, an industry shakeout, and a more rational approach to pricing,” he said. BLOOMBERG
