Alibaba announces Qwen3.8-Max, its largest model to date

Alibaba announced Qwen3.8-Max on 3 August 2026 with 2.4 trillion parameters, about 95 billion active at a time through a sparse mixture of experts, a context window up to 1 million tokens, and native text, image and video input. Weights were scheduled to follow a week later.

Why it mattered Alibaba said it would publish the weights of a trillion-parameter-class multimodal model, a step no American laboratory had taken with a model of that size.
