In 2025, China’s AI landscape is defined by two flagship large language models: Alibaba’s Qwen3 and DeepSeek R2. These models are not only pushing the boundaries in terms of parameter scale, inference efficiency, and cost optimization, but are also setting new standards in multi-modality, intelligent reasoning, and ecosystem openness. This article provides a comprehensive, up-to-date comparison based on the latest public information and community insights.
Release Date: April 29, 2025
Qwen3 offers both Dense (0.5B–32B) and MoE (30B/235B) architectures. The flagship Qwen3-235B-A22B outperforms DeepSeek R1 671B in code, math, and general benchmarks.
(For a detailed comparison of Qwen3 and DeepSeek 32B models, see QwQ-32B vs DeepSeek-R1-32B.)
Trained on 36 trillion tokens—double that of Qwen2.5—covering 119 languages and dialects, significantly enhancing multilingual and cross-domain capabilities.
Dense models (8B+) and all MoE variants support up to 128K context length, enabling long-document reasoning and complex conversations.
Qwen3 MoE models feature seamless switching between “thinking” and “non-thinking” modes, optimizing for both rapid responses and deep reasoning based on task complexity.

Native support for agent scenarios, robust API, and enhanced tool invocation capabilities.
Supports both text and image inputs, with improved agent capabilities for real-world applications.
Release Date: Expected mid-2025 (currently in limited testing)
1.2 trillion total parameters, leveraging Hybrid MoE 3.0 architecture with only 78B (6.5%) active during inference, dramatically reducing compute costs.
Inference cost per million tokens is just $0.07—97% lower than GPT-4 Turbo—making large-scale AI adoption feasible for enterprises.
Trained on 5.2PB of high-quality data spanning finance, law, patents, and more, achieving 89.7% instruction accuracy.
Supports text, image, and audio inputs. Achieves 92.4% mAP on COCO for object detection and 98.1% accuracy in medical diagnostics, surpassing expert groups.
Trained on Huawei Ascend 910B clusters with 82% chip utilization, enhancing China’s AI hardware independence.
Incorporates Generative Reward Modeling (GRM) and Self-Consistent Critique Tuning (SPCT) for superior reasoning and alignment.
Base models are open-sourced and available on platforms like Hugging Face, accelerating AI democratization.

By launching Qwen3 ahead of DeepSeek R2, Alibaba aimed to secure the “first Chinese MoE” narrative, establishing industry mindshare and technical leadership.
Early release forced DeepSeek R2 into a “comparison mode,” reducing its potential impact and positioning Qwen3 as the benchmark for subsequent models.
Qwen3’s broad model matrix and 128K context coverage preemptively addressed potential selling points of competitors, making it harder for others to claim all-round superiority.
The launch generated significant buzz across Zhihu, Weibo, GitHub, and Hugging Face, ensuring Qwen3 dominated the attention economy.
The Qwen3 vs DeepSeek R2 battle is not just about parameters or speed—it’s a contest for market mindshare and the future of China’s AI ecosystem.
The real competition is just beginning.
