Alibaba's Qwen3.8-Max rivals Anthropic's Fable 5 with 2.4T parameters
Qwen3.8-Max beats Kimi K3 on benchmarks, weights free Aug 10.
Alibaba Group released Qwen3.8-Max, its latest flagship AI model built on 2.4 trillion parameters. In benchmark results shared by the company, the model delivers comparable or sometimes better scores than Anthropic's Fable 5—a cutting-edge system that the US temporarily placed under export controls due to its advanced capabilities. Qwen3.8-Max also ranks higher than Moonshot's Kimi K3 on several key benchmarks, a notable feat given the market disruption Kimi K3 caused in July when it showed Chinese developers could quickly catch up with top Western models despite computing constraints.
The Hangzhou-based company intends to release Qwen3.8-Max's weights for public download in the week starting Aug 10, allowing users to fine-tune and customize the technology. Alibaba highlighted strong performance in autonomous coding and long-horizon execution—the model independently managed a software engineering project over 16 days in internal testing. It also introduced efficiency improvements, activating only selective parts of the network when in use to cut computational costs and latency. Alibaba shares surged as much as 7.3% in Hong Kong following the announcement, reflecting growing investor confidence that Chinese AI models are narrowing the gap with US leaders. The release adds to a wave of rapid Chinese AI progress, following DeepSeek's V4 Flash expansion on Jul 31 and Moonshot's Kimi K3 debut, pitting Alibaba against rivals like DeepSeek, Z.ai, and ByteDance in the intensifying race for AI dominance.
- Qwen3.8-Max packs 2.4 trillion parameters and beats Moonshot's Kimi K3 on multiple benchmarks.
- Matches or tops Anthropic's Fable 5 in several tests, which was previously placed under US export controls.
- Weights go public Aug 10; model autonomously completed a 16-day software engineering project.
- Uses selective activation to reduce computational costs and latency during inference.
Why It Matters
Open-source Qwen3.8-Max gives developers a top-tier, customizable alternative and shows China's AI gap with the US is shrinking fast.
