Ant Group’s Bold AI Leap with Ling-1T
Ant Group, the prominent Chinese fintech affiliate of Alibaba Group Holding, recently unveiled and open-sourced its groundbreaking trillion-parameter large language model, Ling-1T. This significant announcement on Thursday, October 9, 2025, marks a pivotal moment in the intensely competitive global race for advanced artificial intelligence capabilities. Ling-1T is positioned as a versatile, general-purpose LLM, specifically engineered to excel in intricate reasoning and logic-based tasks across various domains. The launch underscores Ant Group’s commitment to pushing the boundaries of what AI can achieve.
The model’s technical prowess is considerable, featuring a staggering one trillion total parameters, with approximately 500 billion activated per token during inference. It was rigorously trained on over 20 trillion inference-intensive tokens, a monumental dataset enabling its sophisticated capabilities. Ant Group asserts that Ling-1T surpasses several established open-source and closed-source competitors, including models from DeepSeek, Moonshot AI, and even OpenAI, in crucial performance metrics. These include enhanced code generation, more efficient software development, and advanced competition-level mathematics.
Performance Benchmarks and Strategic Openness
In a demonstration of its advanced mathematical reasoning, Ling-1T achieved an impressive 70.42% accuracy on the challenging American Invitational Mathematics Examination (AIME) benchmark. This performance is notably comparable to that of Google’s highly regarded Gemini-2.5-Pro model, highlighting Ling-1T’s sophisticated problem-solving abilities. Furthermore, the model has shown superior scores on platforms like LiveCodeBench, reinforcing its strength in coding-related tasks. These benchmarks position Ling-1T as a leading contender in the global LLM landscape.
Ling-1T represents Ant Group’s second trillion-parameter model, following the earlier open-source Ring-1T-preview released in September. It is a flagship component of Ant Group’s broader Ling AI model family, also known as BaiLing. This family encompasses three distinct series: the Ling non-thinking models, which include Ling-1T; the Ring thinking models; and the multimodal Ming series. Ant Group’s Chief Technology Officer, He Zhengyu, articulated the company’s philosophy, stating a belief that Artificial General Intelligence (AGI) should serve as a public good. He emphasized the goal of providing
