Qwen3.8 Max Preview

Qwen3.8 Max Preview is Qwen's evolving 2.4T-parameter flagship preview, with major gains over Qwen3.7 Max in coding, professional productivity, full-stack development, data analysis, and office workflows. It always uses thinking mode and supports long-horizon tool workflows and structured output. While in this preview version, requests are processed by Alibaba Cloud which may retain prompts and responses for an unspecified period but does not use them for model training.
