Alibaba’s stock climbed on Monday after the Chinese technology company unveiled Qwen3.8-Max, a 2.4 trillion parameter AI model it says is competitive with Anthropic’s latest systems. The New York-listed shares rose 4.5%, while Hong Kong-listed shares gained 7%, as investors reacted to the release in the middle of a tightening race between Chinese and American AI developers.
Qwen3.8-Max is scheduled for release next week and is the most powerful model in Alibaba’s Qwen family to date, according to the company. Parameters are the numerical settings that shape how an AI model processes information and generates responses, and 2.4 trillion places the system among the largest publicly described models from any Chinese vendor.
What the model can do
Qwen3.8-Max supports a context window of up to 1 million tokens, allowing it to work with text amounts equivalent to thousands of pages in a single session. Alibaba described capabilities across coding, real-life work, research, long-horizon tasks, and visual intelligence.
The company shared benchmark results showing Qwen3.8-Max delivering comparable or in some cases better scores than Anthropic’s Fable 5. The model ranked second behind Fable 5 on the Vision Arena leaderboard and fifth on the Text Arena leaderboard.
Autonomous coding and long-running tasks
Alibaba said Qwen3.8-Max can code autonomously for weeks with limited human input. In one internal test, the model spent 16 days building and improving an AI coding tool on its own by writing code, running tests, fixing errors, and refining its work without intervention.
The model is also positioned for real-world workloads such as reviewing legal documents, conducting financial research, and producing architectural 3D modeling. Its visual intelligence extends to parsing hundred-page documents, television series, or 100-hour livestreams and converting that content into searchable, interactive knowledge hubs.
Where Qwen3.8-Max sits in the Chinese AI race
The release comes shortly after domestic rival Moonshot AI introduced Kimi K3 earlier in the month, a model with 2.8 trillion parameters that is currently China’s largest. Alibaba’s 2.4 trillion parameter system lands just behind that figure and ahead of most other Chinese models on raw size.
Chinese AI developers are competing to close the capability gap with U.S. labs, and parameter counts have become one of the public benchmarks both sides use to signal progress. Alibaba’s choice to publish comparison scores against Anthropic’s Fable 5 reflects that framing.
