qwen3.8-max

A 2.4-trillion-parameter MoE flagship with a major leap in coding and office productivity, able to autonomously code for over ten days to deliver complete projects. It handles hundreds of professional tasks across law, finance, design, and more, delivering production-grade results end-to-end in a single conversation. Native visual understanding runs through the entire planning, execution, and verification pipeline, enabling deep semantic parsing of ultra-long documents and long videos. It plans autonomously and iterates in closed loops during long-horizon tasks, continuously improving.

Rate Limits

This model uses dynamic rate limiting in the China North 2 (Beijing) and Singapore regions. TPM is adjusted based on your monthly QwenCloud spend tier, while RPM has a relatively high limit that you do not need to configure separately and that will not be triggered during normal use.

  • Germany (Frankfurt)
  • China (Hong Kong)
  • Japan (Tokyo)

Scope: InternationalThis region uses dynamic rate limiting. The TPM limit is tiered by your monthly QwenCloud spend, and the RPM limit is high enough that normal use does not trigger throttling. For the tier values, see Dynamic rate limiting.

Snapshot Versions

qwen3.8-max-0902

Qwen3.8-Max-0902 (alias qwen3.8-max-2026-09-02) is an upgraded snapshot of qwen3.8-max. Coding capability breaks new ground, handling more complex engineering-scale projects and long-horizon autonomous development. Collaborative agent performance is significantly enhanced, with greater composure in multi-tool orchestration and end-to-end task delivery. Native vision understanding is refined across chart reasoning, document parsing, and multimodal perception — sharper and more reliable. Retains the 1M context window, thinking mode, and full tool ecosystem, evolving at a higher level of intelligence.
