Synthesized from 2 Yomimono stories · updated Aug 18

Alibaba's Qwen team announced Qwen3.8-Max on August 10, 2026. The model is multimodal, handling text, images, and video, with 2.4 trillion total parameters and 95 billion active parameters. It supports a 1 million token context. In some benchmarks it surpassed Anthropic's Claude Fable 5.

The announcement highlighted a 16-day autonomous run in which the model produced 265 commits and 127 pull requests, reproducing a research paper and proposing 18 improvements. This demonstration was framed as pushing multimodal AI from understanding to continuous autonomous work.

Two days later, reports said Alibaba will make Qwen3.8-Max an open model with open weights, but will require major commercial users to share revenue. The move follows Moonshot AI's Kimi K3 license, which mandates commercial contracts for businesses with annual sales over $20 million. Alibaba's revenue sharing rate is undecided.
