Qwen3.8
The official repository for Alibaba's Qwen3.8 large language model, which brings a top-tier Qwen-Max-class model to open release, with stronger coding, professional-work, research and long-horizon agentic performance.
Qwen3.8 is the latest release in the Qwen3.5 open-model series from Alibaba's Qwen team, following Qwen3.5 and Qwen3.6, and is the first time a Qwen-Max-class model has been made available as an open release. Built on the architectural foundation of Qwen3.5, it improves coding, professional work, research and long-horizon agentic tasks, and is designed to carry complex, multi-step tasks through to completion more reliably rather than only answering harder individual questions.
Its agent-execution capability adds stronger autonomous planning and better handling of environment feedback, reasoning depth can be tuned through a reasoning-effort setting, and reasoning context from earlier messages can be preserved across turns. The repository also documents the two earlier releases in the series: Qwen3.6, which focused on stability and more fluent agentic coding and repository-level reasoning, and Qwen3.5, which introduced a unified vision-language foundation.
