Chinese fintech giant Ant Group has released a new open-source, trillion-parameter large language model (LLM) that boasts stronger maths and coding capabilities than rival models from DeepSeek and OpenAI, escalating the intense competition in artificial intelligence systems.

The new general-purpose Ling-1T model, with 1 trillion parameters, demonstrated “superior complex reasoning ability and overall advantage” against both open-source and closed-source rivals, the company said on Thursday.

It outperformed other major AI models in areas including code generation, software development, competition-level maths and logical reasoning, according to the Hangzhou-based firm.

Ant is an affiliate of Alibaba Group Holding, the owner of the Post.

Ant also touted that on AIME, Ling-1T achieved an accuracy of 70.42 per cent at an average cost of over 4,000 output tokens per problem, on par with Google’s Gemini-2.5-Pro and surpassing those from DeepSeek, OpenAI and Moonshot.

Ling-1T is Ant’s second LLM with 1 trillion parameters. The company last month released Ring-1T-preview, which it claimed was the world’s first open-source, trillion-parameter thinking model.
