TL;DR
Alibaba announced the broad availability of Qwen3.8-Max, revealing detailed benchmark metrics confirming its 2.4 trillion parameters and strong performance in key AI tasks. The release includes open weights for the 27B variant, emphasizing transparency and open deployment potential.
Alibaba has publicly released detailed benchmark performance data for its Qwen3.8-Max model, confirming it as a 2.4 trillion-parameter, sparse mixture-of-experts AI system built on the Qwen3.5 architecture. This marks the first time the model’s active-parameter count and performance metrics are fully disclosed, providing transparency after weeks of speculation and stealth testing.
On August 3, Alibaba made Qwen3.8-Max broadly available, publishing a comprehensive benchmark table that confirms its size, architecture, and multimodal capabilities. The model features approximately 95 billion active parameters per query, operating within a 2.4 trillion-parameter overall structure, and employs sparse mixture-of-experts technology. The benchmark results, obtained using Alibaba’s testing harness, show the model outperforming several competitors on key AI benchmarks such as Terminal-Bench 2.1 (86.6), PaperBench (93.0), and Parametric CAD Bench (91.5). It also demonstrated strong multimodal and agentic performance, reproducing research paper results and outperforming previous models in long-horizon agent tasks.
Alibaba also confirmed that open weights for a 27B variant will be released next week, targeting deployment on high-memory single machines. The 2.4 trillion-parameter checkpoint remains a multi-node datacenter artifact, emphasizing the model’s scale and deployment complexity. The company highlighted that the model’s agentic capabilities have improved significantly over its predecessor, with notable gains in deep software-engineering benchmarks, although it still trails in some areas like SWE-bench Pro.
For fifteen days the claim ran without a benchmark table. Today Alibaba published the table, the active-parameter count, and a weights timeline. The numbers are genuinely strong on the rows Alibaba chose — and twelve to fifteen points behind on the rows it didn’t.
▲ All performance figures: Alibaba’s own harnessThe claim shipped on a Sunday. The evidence shipped two weeks later. In between, the claim did its work.
“Second only to Fable 5” is true on the rows Alibaba chose and false on the rows it didn’t. Both halves below are from the same release.
“Qwen3.8 is going open-weight” describes three things with very different deployment realities.
OpenAI- and DashScope-compatible — a base-URL change to A/B against your current backend.
A multi-node datacenter artifact. At 95B active, no single machine serves it. A flag planted, not a deployment option.
The checkpoint that fits real hardware. Whether the agentic gains survive distillation is the question that decides whether next week matters.
Three Chinese frontier releases in seventeen days, each measured against the same export-controlled model. The contest is real; it is not the same thing as your workload.
- The generation jump is real and consistent across a dozen agentic rows, with a stated mechanism: RL-environment scaling.
- More disclosure than Kimi K3 shipped — full table, active-parameter count, weights timeline.
- If 2.4T lands under a permissive licence, the ceiling of “open weight” moves permanently.
- The 27B sibling could become the best local agent model on hardware people already own.
- Every number is Alibaba’s harness. Independent testing already tempered Kimi K3’s launch claims substantially.
- The paying use case still belongs to Fable 5 — twelve to fifteen points on deep software engineering.
- “Next week” comes from a company that sat on a finished benchmark table for fifteen days.
- Until the licence text exists, “going open-weight” is a press strategy, not a property of the model.
and it says “second only” depends entirely on which row you read.
Implications of Alibaba’s Transparent Benchmark Release
The publication of detailed performance metrics marks a major shift toward transparency in large-scale AI models, allowing researchers and developers to better understand the capabilities and limitations of Qwen3.8-Max. The disclosure of active-parameter counts and benchmark results provides a clearer picture of the model’s true size and performance, which has implications for AI deployment, licensing, and competitive positioning. Additionally, the open release of the 27B weights next week signals a move toward more accessible, high-performance models for broader use, potentially accelerating innovation and adoption in various AI applications.

Background on Alibaba’s AI Model Development and Stealth Launch
Alibaba’s AI model development has been characterized by a period of stealth and selective testing, culminating in the reveal of Qwen3.8-Max at the World AI Conference in Shanghai on July 19. Prior to this, models like Kimi K3 and the anonymous 'kaleb' had generated buzz, but detailed metrics remained undisclosed. The company’s strategy involved a staged rollout, initially previewing the model at a discounted price through its Token Plan, and then gradually unveiling its capabilities via benchmark tables and open weights. The release follows a pattern of high-profile launches by other players like Moonshot’s Kimi K3, emphasizing a competitive landscape in large-scale AI models.
"We are committed to open AI development. The release of detailed metrics and open weights for Qwen3.8-27B reflects our confidence in the model’s capabilities and our dedication to community engagement."

Unconfirmed Aspects of Model Licensing and Deployment
While Alibaba has published detailed benchmark data, the licensing terms for the 2.4 trillion-parameter weights remain unpublished, raising questions about usage rights and restrictions. It is also unclear whether the open weights for the 27B variant will include full licensing details or be subject to future restrictions. Additionally, the true operational performance of the model in real-world applications, outside benchmark settings, is still to be tested and validated.

Next Steps for Model Deployment and Community Engagement
Alibaba plans to release the 2.4 trillion-parameter open weights next week, enabling researchers and developers to experiment with the model directly. The company also intends to gather feedback on the 27B variant’s performance, which is expected to be optimized for deployment on single high-memory machines. Further benchmark results and licensing details are anticipated in the coming weeks, alongside potential updates to the model’s capabilities based on community testing and feedback.
