Alibaba previews Qwen3.8, claims it’s second only to Claude Fable 5

Alibaba Group Holding Ltd. today previewed Qwen3.8-Max-Preview, a 2.4 trillion-parameter AI model, at the World Artificial Intelligence Conference in Shanghai, claiming it ranks second only to Anthropic PBC's Claude Fable 5 among frontier models. The company provided no benchmark scores or independent verification to support the claim, and the preview lacks a model card, activated-parameter count, or task-level comparison with its predecessor Qwen3.7-Max. The release positions Qwen3.8 against domestic rival Beijing Moonshot AI Technology Co. Ltd.'s Kimi K3, a 2.8 trillion-parameter model released three days earlier, as Chinese developers enter the multi-trillion-parameter tier.

Alibaba previews Qwen3.8, claims it’s second only to Claude Fable 5 Alibaba Group Holding Ltd. today previewed the most powerful artificial intelligence model in its Qwen family, Qwen3.8, and claimed the system trails only Anthropic PBC’s Claude Fable 5 among the world’s frontier models. The company revealed the model, offered as a preview build called Qwen3.8-Max-Preview, today at the World Artificial Intelligence Conference in Shanghai. It accommodates 2.4 trillion parameters, making it the first Qwen model above 1 trillion parameters to process images, video and documents alongside text. Alibaba’s Qwen team said in a post on X https://x.com/Alibaba Qwen/status/2078759124914098291 that the model ranks “second only to Fable 5,” a reference to Anthropic’s recent release. It offered no benchmark scores to support the claim and no independent evaluation has verified the ranking. That absence stands out. Alibaba’s previous flagship, Qwen3.7-Max, shipped in May with a full set of published results, including a score of 56.6 on the Artificial Analysis Intelligence Index https://artificialanalysis.ai/ . The Qwen3.8 preview arrived with no model card, no activated-parameter count and no benchmark data at all. Alibaba published no task-level comparison with Qwen3.7-Max and described the new model only as “continuously evolving.” Open weights are promised “soon,” though the company has not set a date or published license terms. The preview is available now through Alibaba’s Token Plan subscription and its Qoder and QoderWork developer platforms, priced at 10% of the standard rate during the trial period. The timing places Qwen3.8 directly against a domestic rival. Chinese AI startup Beijing Moonshot AI Technology Co. Ltd. released Kimi K3, a 2.8 trillion-parameter model, three days earlier https://siliconangle.com/2026/07/16/chinas-moonshot-throws-gauntlet-kimi-k3-worlds-largest-open-weights-model/ . Both launches push Chinese developers into the multi-trillion-parameter tier, a scale until recently associated mainly with the largest U.S. labs Alibaba has made Qwen central to its effort to position itself as China’s default AI supplier. Over the past year the company has released a steady run of open-weight models while building out cloud infrastructure and custom chips to run them. The open-weight approach has helped Qwen assemble one of the largest developer followings of any Chinese model family, a base it now hopes to carry into the trillion-parameter class. For enterprise buyers weighing the announcement, the comparison with Fable 5 is Alibaba’s alone. No independent leaderboard has scored Qwen3.8 yet, and the last Qwen model that was ranked, Qwen3.7-Max, sits well down LMArena’s list, where Fable 5 is No. 1. Benchmarks and the promised open weights would settle it, but Alibaba has released neither.
