Alibaba's Qwen3.8-Max tops agentic benchmark, open-sources next week

Alibaba's Qwen team released its flagship model Qwen3.8-Max on August 6. Based on a Sparse MoE architecture with 2.4T total parameters and 95B active parameters, it tops the Artificial Analysis Agentic Index and ranks fifth overall in the Intelligence Index with a score of 56. The model is available via Alibaba Cloud API and the enterprise platform QwenWork, with open-source weights planned for next week.

Confirmed

• Model scale and architecture: Sparse MoE, 2.4T total parameters, 95B active, balancing performance and efficiency (m2, m4).
• Benchmark results: Ranked #1 on Artificial Analysis Agentic Index; #5 overall with score 56, up 10 points from previous generation, tying Claude Opus 4.8 (m1, m2, m3).
• Services and ecosystem: Available via Alibaba Cloud Model Studio API and integrated into QwenWork; services open to global users (m4, m7).
• Open-source plan: Weights to be released on Hugging Face next week (m7).

Unconfirmed

• Context length: m8 mentions 1M token context, not officially confirmed.
• Medical RL training: m6 mentions upcoming medical RL training, but it's a repost and unverified.
• Autonomous CLI tool building: m10 claims the model built a CLI tool autonomously over 16 days, but it's a personal experience, not officially confirmed.

Why it matters

Qwen3.8-Max's leading performance on agentic tasks marks a breakthrough for domestic models in agentic capabilities. Its efficient active parameter design balances performance and inference efficiency, and with the upcoming open-source release, it holds significant practical value for AI application deployment and the open-source community.
