TL;DR
Alibaba announced the full benchmark results for its Qwen3.8-Max model, showing it surpasses many competitors in specific tasks but falls short in others. The model’s open weights will be released next week, marking a significant step for open AI models.
Alibaba has confirmed the specifications and benchmark performance of its Qwen3.8-Max model, a 2.4 trillion-parameter AI, and announced that its open weights will be available next week. This development challenges previous perceptions of the model’s capabilities and marks a significant milestone for open AI models, especially given the model’s size and performance metrics.
On August 3, Alibaba officially published the full benchmark table for Qwen3.8-Max, revealing a model built on a sparse mixture-of-experts architecture with approximately 95 billion active parameters per query. The model, which debuted as a stealth preview during the July World AI Conference, now has verified performance metrics across multiple benchmarks, including Terminal-Bench 2.1 (86.6), PaperBench (93.0), and IFBench (82.8). These results position Qwen3.8-Max ahead of many competitors like Claude Opus 4.8 and Fable 5 in several areas, though it trails behind GPT-5.6 Sol at maximum effort.
The model demonstrates notable strengths in multimodal and agentic tasks, achieving high scores in OSWorld-Verified (86.1), Parametric CAD Bench (91.5), and OmniDocBench (92.1). Its long-horizon reasoning capabilities have improved significantly, with a leap in agentic execution from previous versions, notably in DeepSWE (from 21.6 to 56.6). However, in deep software engineering benchmarks such as SWE-bench Pro and FrontierSWE, it underperforms compared to Fable 5, with gaps of 12 to 15 points.
Alibaba’s announcement also clarified that the 2.4 trillion parameters are largely a theoretical total, with active parameters per query around 95 billion, and the model employs sparse mixture-of-experts techniques. The full benchmark table was published using Alibaba’s own testing harness, confirming the model’s competitive performance in several key areas. The upcoming open weights, due next week, will be a multi-node datacenter artifact, not suitable for individual hosting, but they mark the largest open-weight model ever shipped if fully released.
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 Qwen3.8-Max's Benchmark Performance
The verified benchmark results demonstrate that Alibaba's Qwen3.8-Max is a major contender in the AI landscape, especially in multimodal and agentic tasks, challenging assumptions about the capabilities of large-scale models. The upcoming open weights will enable wider experimentation and deployment, potentially shifting the competitive dynamics of AI development. However, the model’s performance gaps in software engineering benchmarks highlight ongoing limitations and the importance of targeted improvements for real-world applications.
This development underscores the increasing transparency in AI model capabilities and the importance of detailed benchmarking, influencing both industry strategies and investor confidence. The fact that Alibaba’s shares rose following the announcement reflects market interest in the model's potential, even as questions about licensing and practical deployment remain.

Background on Alibaba's AI Model Development
Alibaba’s Qwen series has been developed over recent years, with the company initially revealing only limited details about its models. The July preview of Qwen3.8-Max created significant industry buzz, as it was introduced stealthily and only confirmed during the World AI Conference in Shanghai. Prior to this, Alibaba’s models had been primarily used internally or in limited beta tests, with the company gradually revealing performance metrics through selective benchmarks.
The model’s size—initially claimed as 2.8 trillion parameters—was publicly questioned until the full benchmark table was published, confirming a 2.4 trillion-parameter total with approximately 95 billion active parameters per query. This marked a shift from speculative claims to verified performance data, aligning with Alibaba’s broader strategy to increase transparency and competitiveness in AI research.
"The full benchmark table confirms our model's strengths and areas for improvement, and the open weights will be available next week for broader experimentation."
— Alibaba spokesperson
Remaining Questions About Model Licensing and Deployment
It is still unclear what the final licensing terms for the open weights will be, and whether they will be as permissive as Alibaba’s previous open models. The practical deployment of the 2.4 trillion-parameter checkpoint remains limited to datacenter environments, making it inaccessible for individual researchers and developers. Additionally, the long-term performance of the model’s agentic capabilities, especially in real-world applications, is still under evaluation.
Next Steps for Alibaba’s AI Model Strategy
Alibaba plans to release the open weights next week, enabling broader testing and deployment. Industry observers will closely examine the model’s performance in real-world tasks and its licensing terms. Further benchmark releases and updates on practical applications are expected in the coming months, alongside potential improvements based on community feedback and internal research.
