Hong Kong —

Remember DeepSeek? The Chinese artificial intelligence startup that rattled the US tech industry with its model that nearly matched leading rivals, trained at a fraction of the cost?

China may have done it again.

The latest Chinese AI model making waves was developed by a lesser-known startup called Moonshot AI. In just two days after launch, Moonshot suspended new subscriptions after demand overwhelmed its computing capacity.

The unexpected enthusiasm for Moonshot’s Kimi K3 model stems from its ability to match – and in some cases outperform – its most advanced US competitors, such as the latest iterations of OpenAI’s GPT and Anthropic’s Claude, for free.
