TL;DR
Alibaba announced the broad availability of its Qwen3.8-Max AI model, revealing benchmark scores and confirming open weights will ship next week. The model features 2.4 trillion parameters and shows competitive performance in several benchmarks, signaling a significant development in large language models.
Alibaba has confirmed the broad availability of Qwen3.8-Max, a large language model with 2.4 trillion parameters. The company published detailed benchmark scores and announced that open weights will be shipped next week, marking a significant milestone in its AI development.
On August 3, Alibaba unveiled the full benchmark table for Qwen3.8-Max, which had been withheld since its preview in July. The model is built on the Qwen3.5 architecture, uses sparse mixture-of-experts, and supports multimodal input—text, image, and video—with text output. The active-parameter count is approximately 95 billion per query, with the total parameters at 2.4 trillion.
The benchmark results show Qwen3.8-Max outperforming several competitors in key tests: it scored 86.6 on Terminal-Bench 2.1, surpassing Claude Fable 5 and only behind GPT-5.6 Sol. It achieved top scores on PaperBench (93.0) and demonstrated strong multimodal and agentic capabilities, notably improving in long-horizon tasks and agentic execution relative to its predecessor. Alibaba also confirmed that the model can reproduce research results and outperform previous models on specific tasks like AIME24, with notable gains in agentic benchmarks.
The company clarified that the 2.4 trillion parameters are a theoretical total, with about 95 billion active parameters per query, and that the open weights, due next week, will be a checkpoint suitable for deployment on high-memory hardware. The open weights will be available under unspecified licensing, with the model’s deployment primarily via API, compatible with OpenAI and DashScope interfaces.
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 AI Benchmark Performance
The release of detailed benchmark scores and upcoming open weights signifies a major step for Alibaba in the large language model landscape. The model's strong performance in key benchmarks like Terminal-Bench and PaperBench demonstrates its competitiveness against established players like OpenAI and Anthropic. Additionally, the open weights will enable broader access for developers and researchers, potentially accelerating innovation and deployment in multimodal and agentic AI applications.
However, the model's performance varies across benchmarks, with notable gaps in deep software engineering tasks, such as SWE-bench Pro, where it trails behind Fable 5. The distinction between the 2.4 trillion total parameters and the approximately 95 billion active parameters per query highlights the model's sparse architecture, which influences its practical deployment and scalability. Overall, this development signals a significant push by Alibaba into the large-scale AI arena, with implications for competition, open-access AI development, and future capabilities of multimodal models.

Background and Recent Developments in Alibaba's AI Strategy
Alibaba's AI journey has been marked by strategic teasers and stealthy previews, culminating in the July preview of Qwen3.8-Max, which was initially introduced via an anonymous model called 'kaleb' at the Code Arena leaderboard. The company confirmed its identity during the World AI Conference in Shanghai on July 19, after a series of teasers and limited previews. Prior to this, Alibaba's AI models had been less publicly detailed, with the company focusing on building a competitive large language model ecosystem.
The model's announcement follows a period of intense activity in the AI industry, characterized by high-profile launches such as Moonshot's Kimi K3 and the emergence of other large models. Alibaba's approach involved a staged reveal, starting with a stealth preview, then limited access via a paid endpoint, and now full benchmark disclosure and open weights, reflecting a strategic effort to build credibility and showcase capabilities.
Historically, Alibaba's open models have shipped under Apache 2.0 licenses, but the upcoming release of the 2.4 trillion parameter checkpoint remains uncertain in licensing terms. The company emphasizes that the open weights will be a multi-node datacenter artifact, not suitable for individual hosting, but the 27B checkpoint will be designed for local deployment.
"Qwen3.8-Max demonstrates the company's commitment to advancing multimodal and agentic AI capabilities, with benchmark results confirming its competitive edge."

Unresolved Questions About Open Weights and Licensing
While Alibaba confirmed that open weights will be shipped next week, details about the licensing terms remain unpublished. It is unclear whether the open weights will be under a permissive license like Apache 2.0 or a more restrictive one, which could impact adoption. Additionally, the performance of the 27B checkpoint—derived from the 2.4T model—on various benchmarks and real-world tasks is still to be evaluated once released.
It is also uncertain how the model's agentic capabilities will hold up in practical deployments, especially given the gaps in deep software engineering benchmarks. The long-term impact of the model's architecture and sparse mixture-of-experts design on scalability and efficiency remains to be seen.
Upcoming Release of Open Weights and Benchmark Evaluations
Next week, Alibaba plans to release the open weights of Qwen3.8-Max, enabling broader testing and deployment. Researchers and developers will likely scrutinize the model's performance across benchmarks and real-world applications, especially in multimodal and agentic tasks. Meanwhile, the company may publish further details about licensing and usage terms.
Industry watchers will be monitoring how the open weights influence the competitive landscape, especially against models like GPT-5.6 and Claude Fable 5. The model's long-term impact on AI capabilities and open-access development will become clearer as more tests and deployments occur.
