On November 11, Alibaba Cloud opened a preview of its next-generation flagship model, Qwen4-Max, through its Model Studio. The multimodal model accepts text, image and video input with deep reasoning, supports a 1-million-token context and up to 393,216 tokens of output, and is compatible with OpenAI Chat Completions, Responses and Anthropic Messages interfaces, with function calling, web search and structured output.
The preview runs from November 11 to November 25 and is available only via a Token Plan subscription rather than pay-as-you-go; Alibaba has not yet published benchmark scores or parameter scale. The release extends Alibaba's Qwen family - already one of the world's most widely used open and commercial model lines - into the next flagship generation.
