Qwen3.8-Max: A New Bar for Coding and Cowork

Alibaba Group Holding Ltd released its latest flagship artificial intelligence model Qwen3.8-Max on Aug. 3, the company announced. The model is built around 2.4 trillion parameters and ranks higher on some benchmarks than the recently unveiled Kimi K3 from Moonshot. Alibaba intends to release the weights for public download next week. The debut marks the next major move in the intensifying race among China's AI developers that include Moonshot, DeepSeek and ByteDance Ltd. DeepSeek expanded access to its latest model, V4 Flash, last week. The new Qwen3.8-Max performs well in autonomous coding and long-horizon execution and was able to independently execute a software engineering project over 16 days in internal testing, Alibaba said. The system has also improved in efficiency, activating only segments of its 2.4 trillion parameters when in use to reduce computational costs and latency. Alibaba showed it ranking only behind Anthropic's releases in a pair of Arena Leaderboard benchmarks.
