Bloomberg Intelligence reported that the performance gap between top US and Chinese AI models narrowed to a record low of about 3% on benchmark scores following the September release of DeepSeek’s V4.1 Flash. The analysis by senior analyst Robert Lea notes the spread has fallen from roughly 9% in May and 15% earlier in 2026, raising questions about the durability of US technological lead and potential further market-share gains for Chinese models.
