What changed
Qwen4-Max-Preview is a new preview model in Alibaba's Qwen family, combining text generation, image and video understanding, reasoning, web search, tool calling, and structured outputs. Alibaba documents a 1-million-token context length and OpenAI and Anthropic API compatibility.
Access and availability
Choose Token Plan Personal or Token Plan Team, obtain a dedicated API key using Alibaba Cloud's guide, then call model ID qwen4-max-preview through the documented Token Plan endpoint.
Official access documentationWhat you can build
Treat this as a time-limited preview, and validate multimodal and tool-calling behavior before relying on it in an application.
Limitations
This is a preview available only through Token Plan, not pay-as-you-go. Alibaba states the preview runs through November 25, 2026 UTC+8 and the model will be retired afterward. The maximum output budget is shared between reasoning and final response.
