Alibaba, the Chinese tech giant, has introduced Qwen 3, a new suite of AI models that the company asserts can rival and even surpass the leading offerings from competitors such as Google and OpenAI. The models, available for download under an open license from platforms like Hugging Face and GitHub, vary significantly in scale, with sizes ranging from 0.6 billion to a staggering 235 billion parameters. Generally, a model’s parameter count is indicative of its problem-solving capabilities, with larger models typically demonstrating superior performance.
The emergence of models like Qwen 3 puts additional pressure on American AI labs to innovate more rapidly, prompting policymakers in the U.S. to restrict exports of semiconductor chips to Chinese firms, which are essential for training AI models.
Alibaba claims that Qwen 3 incorporates “hybrid” models, capable of both reasoning through complex challenges and quickly addressing simpler queries. This feature mirrors the self-fact-checking ability found in some of OpenAI’s models, albeit with a potential trade-off in response time. The Qwen team explains that they have merged thinking and non-thinking modes, granting users the flexibility to tailor the computational resources allocated to specific tasks.
Some of the Qwen 3 models utilise a mixture of experts (MoE) architecture, enhancing efficiency by allowing the system to break down tasks and assign them to smaller, specialised models. Additionally, the Qwen 3 models support 119 languages and were trained on a colossal dataset comprising nearly 36 trillion tokens, which consists of diverse data sources such as textbooks, code snippets, and AI-generated information.
The improvements seen in Qwen 3 over its predecessor, Qwen 2, have reportedly significantly enhanced its capabilities. While Qwen 3 models do not uniformly dominate the AI landscape, they hold impressive standings against other state-of-the-art models like OpenAI’s o3 and o4-mini. Notably, the largest model, Qwen 3-235B-A22B, has shown competitive results on various benchmarks, besting both OpenAI’s and Google’s models in key areas, though it is not yet publicly accessible.
The largest publicly available model, Qwen 3-32B, also demonstrates competitiveness, particularly in coding benchmarks, outperforming several proprietary and open-source models, including DeepSeek’s R1 and OpenAI’s o1.
Beyond their impressive technical capabilities, Qwen 3 models excel in tool-calling and adhering to specific instructions. They are accessible through cloud services like Fireworks AI and Hyperbolic. Experts, including Tuhin Srivastava from AI cloud host Baseten, affirm that Qwen 3 signifies a significant trend of open-source models effectively competing with closed-source alternatives. Despite increasing restrictions from the U.S. regarding semiconductor exports to China, the availability of advanced, open-source models like Qwen 3 will likely support domestic applications and further innovation in the AI arena.
