The performance gap between top Chinese and U.S. AI models has narrowed to just 3% in benchmark scores, marking a historic low according to Bloomberg Intelligence. Senior analyst Robert Lea reported that China's leading models trailed U.S. counterparts by approximately 9% in May and 15% at the start of the year, with the latest improvement driven by DeepSeek's release of V4.1 Flash in September. Lea projects that these continued performance gains will enable Chinese AI developers to further expand their market share as the technological disparity diminishes.
