Overview
Qwen3.8-Max-Preview is the preview of the next flagship in Alibaba's Qwen-Max line, unveiled by the Qwen team on July 19, 2026 during the World Artificial Intelligence Conference (WAIC) in Shanghai. Alibaba describes it as a 2.4-trillion-parameter model and as its first Qwen model above one trillion parameters to accept images, video, and documents alongside text — making it a multimodal successor to the text-only Qwen3.7-Max.
The preview is available through the Alibaba Cloud Token Plan subscription and the company's Qoder and QoderWork agentic platforms, priced during the trial period at 10% of the standard rate. Alibaba has not published a benchmark table, a model card, an activated-parameter count, or a formal license; the Qwen team has said the model is "continuously evolving" and that open weights will follow, without committing to a date.
Alibaba's own positioning claim is that Qwen3.8-Max-Preview is second only to Anthropic's Claude Fable 5 among today's frontier systems. No third-party leaderboard (Artificial Analysis, LMArena, or otherwise) had independent scores for the model at launch, so treat every quality claim about Qwen3.8-Max as unverified until the Qwen team publishes an official benchmark table or an external evaluator reports numbers.

Strengths
- First Qwen model above one trillion parameters to accept images, video, and documents alongside text
- 2.4-trillion-parameter scale, making it one of the largest models previewed to date (alongside Moonshot's Kimi K3)
- Delivered as the flagship of the Qwen-Max agent line — positioned by Alibaba against Anthropic's Claude Fable 5
- Preview access is available immediately through Alibaba's Token Plan, Qoder, and QoderWork at 10% of standard pricing
Best for
- Frontier reasoning and general-purpose tasks where the previous Qwen-Max flagship was competitive
- Multimodal analysis of images, video, and documents alongside text prompts
- Coding, full-stack development, data analysis, and office workflows (the tasks the Qwen team called out in its preview announcement)
- Note: no independent benchmarks exist yet — until they do, every performance claim about Qwen3.8-Max should be treated as unverified

FAQ
Has Qwen3.8-Max been released?
It is available as a preview, not a general release. The Qwen team unveiled Qwen3.8-Max-Preview on July 19, 2026 at the World Artificial Intelligence Conference in Shanghai, offered through the Alibaba Cloud Token Plan, Qoder, and QoderWork at 10% of standard pricing during the trial period. Alibaba has not published an official model card, benchmark table, or license.
What are Qwen3.8-Max's specs?
Alibaba has disclosed only that Qwen3.8-Max has 2.4 trillion total parameters and is its first Qwen model above one trillion parameters to accept images, video, and documents alongside text input. The active-parameter count, the context window, the training data, and the architecture have not been officially published. Third-party recaps have suggested a 1M-token context window, but this is not confirmed by the Qwen team.
Is Qwen3.8-Max open-source or open-weight?
Not yet. Qwen3.8-Max-Preview is a proprietary preview served through Alibaba's own platforms. The Qwen team has said that open weights will follow, but has not published a license or a release date.
How does Qwen3.8-Max compare to Claude Fable 5 or Kimi K3?
Alibaba's own positioning claim is that Qwen3.8-Max is second only to Anthropic's Claude Fable 5 among the systems the Qwen team benchmarked. Independent leaderboards (Artificial Analysis, LMArena) had no scores at launch, so this ranking is Alibaba's internal claim, not a verified third-party result. Moonshot's Kimi K3, previewed three days earlier at 2.8 trillion parameters, is the other headline preview in this weight class.
