K3 forms the basis for why the stock looks different than it would a month ago. The open weight model outperformed all its rivals except Anthropic’s Claude Fable 5 and OpenAI’s GPT-5.6 on certain parameters, and completely surpassed a widely watched coding benchmark, sparking a semiconductor sell-off on Friday that dragged down cryptocurrencies.
However, Moonshot doesn’t move alone. China’s Alibaba said Sunday that its Qwen3.8 model will become open weight, a 2.4 trillion-parameter system that the company says trails only Fable 5 among cutting-edge models. A preview version, Qwen3.8-Max, is now available on Alibaba Developer Tools.
Open weights allow anyone to run a model without paying its manufacturer, putting pressure on the pricing power of US providers who charge by the token.
A parameter is one of the internal dials that a model adjusts during training to improve text prediction. Modern models have billions or trillions of them, and the count is the approximate and imperfect shorthand the industry uses for raw size.
Bitcoin has been marketed as an indicator of the AI capital cycle all month, and its miners have become owners of AI data centers whose leases depend on maintaining computing demand.
The next reading will come this week, when Alphabet, Tesla and Intel report results that will show whether capital spending on AI continues to rise and whether the miners betting on it remain balanced.
