Alibaba shares rally after unveiling its 'most powerful' AI model as U.S.-China competition heats up

Alibaba released Qwen3.8-Max, a large AI model with 2.4 trillion parameters (numerical settings that control how AI processes information) and a context window of up to 1 million tokens (meaning it can work with thousands of pages of text at once). The model performs comparably to competitor systems and can handle complex tasks like coding autonomously for weeks, reviewing legal documents, and analyzing long videos.
