❯ Alibaba opens Qwen4-Max preview through Token Plan for multimodal coding and complex workflows

A flagship model enters a limited previewAlibaba’s Qwen4-Max-Preview is available through Token Plan, combining text, image and video inputs with reasoning for coding, office work, interface design and complex agent tasks. The preview runs from November 11 at 10 a.m. through the end of November 25, Beijing time, with no changes during that period and retirement afterward. Access currently requires a plan rather than usage-based billing.

Understanding feeds into tool useThe model supports web search, tool calls and structured output, allowing it to analyze screenshots, documents or video and pass results into software workflows. Developers could use an interface screenshot to guide frontend code or request extracted material in a specified data structure. Compatibility with OpenAI’s Chat Completions and Responses APIs and Anthropic’s Messages API helps existing applications connect.

Long tasks share an output budgetThe preview offers a one-million-token context and a combined reasoning-and-answer output limit of 393,216 tokens, with xhigh reasoning enabled by default. Developers must allow room for both intermediate reasoning and the delivered answer. For office and software-operation workflows, the preview provides a period to test multimodal input, execution steps and long-context behavior within existing tools.

▮ SIGNALExisting API compatibility and tool use move Qwen4-Max testing beyond individual answers to complete workflows, lowering integration costs for developers comparing models inside their applications.
