MODEL PREVIEWS

Qwen4-Max-Preview opens with a fixed Token Plan evaluation window

By IDAKIM Digital · Published November 11, 2026

Alibaba Cloud documents multimodal inputs, tool calling and a scheduled retirement after the preview.

Alibaba Cloud’s November 11 documentation introduces qwen4-max-preview through Token Plan only; pay-as-you-go access is not supported for this preview. The stated window runs from November 11 at 10:00 to November 25 at 24:00, UTC+8, after which the model will be retired. It supports text generation, image and video understanding, tools and structured outputs, with OpenAI Chat Completions, Responses and Anthropic Messages compatibility. Thinking is enabled by default. An important integration detail is that max_tokens and max_completion_tokens both limit the combined reasoning and final-answer budget for this model, so a setting previously sized only for an answer may truncate output. The documentation also specifies handling for preserved thinking in multi-turn Chat Completions. The preview is suitable for controlled comparisons, but its planned retirement means an integration needs a fallback rather than treating the identifier as a permanent production dependency.

Why it matters

Test multimodal and tool workflows behind a switchable model configuration. Reserve output budget for reasoning, validate protocol behavior and arrange migration before the preview closes.
