Model details

Qwen3.8 Max Preview

As the preview build of Alibaba's next flagship, Qwen3.8 Max Preview arrives on the Token Plan as a 2.4-trillion-parameter multimodal model that accepts text, image, and video and is designed for long, complex tasks. Reporting describes the system as built on the Qwen 3.5 architecture, pairing the 2.4 trillion total parameters with roughly 95 billion activated parameters, so the model can keep an extremely wide context active without invoking the full parameter count on every token. That combination of broad context and multimodal input makes the preview well suited to software-architecture work, agent-style tool use, and other workflows where a single session has to ingest large repositories or documents and reason across them.

Alibaba's own positioning frames Qwen3.8 Max Preview as second only to its Fable 5 reference, and the preview's reported numbers include scores of 93.0 on PaperBench and 82.8 on IFBench, though independent analysts note those figures lean heavily on Alibaba's own evaluation harness. In a head-to-head StackPerf comparison against Moonshot's Kimi K3, the two systems reached the same integration design and finished within three points, signaling that the preview is operating at a competitive tier for coding and tool-use tasks rather than as a cautious mid-range release. Practical strengths therefore sit in long-context reasoning, multimodal understanding, and agent-style orchestration, while teams should weigh the benchmark provenance when planning mission-critical deployments.

Alibaba released Qwen3.8-Max on August 3, 2026 as a free, open-weight 2.4 trillion parameter model that claims wins over Claude Opus 4.8 on several benchmarks and splits results with GPT-5.6 Sol, including a reported 93.0 score on PaperBench and 82.8 on IFBench. Alibaba said the weights would be published on Hugging Fa The article notes that benchmark scores come largely from Alibaba's own testing harness and should be read with care, but argues the pricing and public weights still threaten the economics of paid frontier AI by giving developers a near-frontier alternative without vendor lock-in.

Alibaba's Qwen team released Qwen3.8-Max on August 3, 2026, the latest and most powerful model in the Qwen family, built on the Qwen 3.5 architecture with 2.4 trillion total parameters, 95 billion activated parameters, and a 1 million-token context window. The company said model weights would be made publicly available The Qwen3.8 API service is priced at 12 yuan ($1.7) per million input tokens and 36 yuan per million output tokens for China users, while overseas developers are charged $2 per million input tokens and $6 per million output tokens, with implicit cache-hit pricing at $0.25 per million tokens.

An infrastructure-focused analysis of Qwen3.8-Max-Preview notes that as of July 22, 2026, Alibaba had published no benchmark table, no model card on Hugging Face, no license, no open-weight date, and no active-parameter count, despite the preview going live. The model is callable through Alibaba's Token Plan subscripti The analysis argues the headline 2.4T number is the wrong planning figure: in a sparse MoE, total parameters set the memory floor while active parameters set the compute bill, and Alibaba withheld the latter, making external cost modeling impossible. By contrast, DeepSeek V4 Pro (1.6T total, 49B active) and GLM-5.2 (74
