Why it matters
This event highlights the hardware and infrastructure bottlenecks facing AI startups as they attempt to scale powerful models in a competitive global market.
HONG KONG -- The new, powerful Chinese artificial intelligence model Kimi K3, which has caused a stir in the U.S. tech industry, has suspended new subscriptions after a flood in demand overwhelmed capacity within days of the launch.
The development highlighted challenges faced by Chinese AI models in serving a growing user base at home and abroad at a time the U.S.-China tech race is heating up.
Chinese open-source, lower-cost advanced AI models, including DeepSeek’s latest V4, have been moving fast in gaining global attention. In early 2025, DeepSeek shook world markets and helped China to be recognized as a serious competitor to the U.S. , where Chinese frontier AI models are largely open source, meaning they are made accessible for people to examine and build upon.
