Qwen3.8-Max: An AI That Codes for 16 Days, Beats 458 Humans, and Opens Its Weights
Qwen3.8-Max: A New Bar for Coding and Cowork
Qwen releases Qwen3.8-Max, a 2.4-trillion-parameter model that autonomously codes for over 10 days, reproduces and improves a research paper, and beats 87% of human teams in a 24-hour contest. It also demonstrates broad professional competence across hundreds of jobs, from legal review to UI design. Open weights arrive next week.
Working completely on its own for about five days (~125 hours of continuous effort), Qwen3.8-Max wrote roughly 7,600 lines of code, took over 1,100 actions, and ran 33 rounds of GPU training.
