On November 11, Alibaba Cloud opened Qwen4-Max-Preview (model ID qwen4-max-preview), the next-generation flagship multimodal model in the Qwen family. It takes text, images, and video. It thinks by default, and you can adjust how much it reasons. It supports function calling, web search, built-in tools, and structured outputs. It works with the OpenAI Chat Completions, Responses, and Anthropic Messages APIs. It has a 1M-token context and up to 393,216 output tokens, and thinking and the answer share that limit. Access is through Token Plan only, with no pay-as-you-go option. The preview runs from 10:00 on November 11 to 24:00 on November 25, 2026 (UTC+8) (11:00 AM ET on November 25), and the model is retired when it ends. Source: Alibaba Cloud Model Studio docs.
