Alibaba previews Qwen 3.8 Max, a 2.4-trillion-parameter model it claims is second only to Fable 5

Alibaba unveiled a preview of Qwen 3.8 Max, a 2.4-trillion-parameter multimodal model the company says is its first model above a trillion parameters and which it claims is 'second only to Fable 5,' Anthropic's flagship, among frontier systems. The model spans text, images, video, and documents and is available in preview through Alibaba's Token Plan and Qoder platforms, with the open-weight release expected shortly. The market rewarded the claim: Alibaba's stock rose 5.4%.

Technically, the leap past a trillion parameters and the multimodal scope mark Alibaba's most ambitious frontier attempt, and the Qwen team says the preview is 'getting better by the day' with a big step up on web frontend generation. The open-weight commitment is the strategic differentiator — it continues the Chinese labs' pattern of shipping capable models as open weights, in contrast to closed U.S. frontier systems.

Competitively, this is the centerpiece of the week's China open-weight surge, alongside Moonshot's Kimi K3 (so popular it paused new signups) and Z.ai's GLM-5.2. Analysts say the wave shows China's top labs keeping pace with the U.S. frontier and pressuring U.S. tech stocks, and it directly feeds the U.S. policy debate over banning cutting-edge Chinese models. Skeptics on r/LocalLLaMA pushed back hard: 'who can actually run 2.4T?' and open doubt about the unverified 'second only to Fable 5' benchmark claim (~58% positive sentiment). Watch for the open-weight drop, independent benchmarks, and whether the parameter count translates into usable, affordable inference.
