Qwen3.8-2.4T-A95B

Qwen3.8-Max, commonly referred to as Qwen3.8-2.4T-A95B, is Alibaba's flagship large language model released August 3, 2026. With 2.4 trillion total parameters (about 95 billion active per token) in a sparse MoE architecture with hybrid attention, it is the largest Qwen model ever built — roughly 10× the total parameters of the Qwen3-235B-A22B released in April 2025.

Model Specifications

Key Features

• First open-weight Max-class Qwen: Qwen3.8-Max is the first Max-class Qwen promised to be open-sourced, with weights scheduled for the week of August 10, 2026 on Hugging Face and ModelScope (companion dense model Qwen3.8-27B also promised).
• Native multimodality: Text, image, and video understanding in a single model, with a top-2 ranking on the Vision Arena leaderboard.
• Long-horizon agentic capability: A 10-day autonomous coding demo and strong terminal/coding agent scores.
• Massive context: 1M-token context window with a 262K-token reasoning budget.

Pricing

Batch API usage is 50% of list pricing. At $2/$6 per million tokens, Qwen3.8-Max costs roughly one-third of Claude Fable 5's list rate ($15/M output). Thinking tokens count as output tokens.

Notes

Open weights were promised for the week of August 10, 2026, but as of August 13 they had not yet appeared on the official Qwen Hugging Face organization page. The license had not been disclosed; precedent Qwen releases shipped Apache 2.0. Alibaba shares rose 7% on release day.

Conclusion

Qwen3.8-2.4T-A95B thrusts Alibaba into the top tier of global frontier models, ranking #1 on PaperBench and OSWorld while undercutting closed competitors on price. If the open-weight promise is fulfilled, it will be the largest permissively-licensed model ever released — a milestone for the open-source AI community.
