Chinese fintech giant Ant Group has open-sourced an inference framework for a relatively new type of artificial intelligence model that it said could make AI systems more efficient, surpassing a framework proposed by researchers at US chipmaking giant Nvidia.

The Alibaba Group Holding affiliate said Monday that its framework, dInfer, was designed for diffusion language models – a newer class of models that generate outputs in parallel, unlike “autoregressive” systems used in large language models (LLMs) such as ChatGPT, which produce text sequentially from left to right.
