How to build a diffusion language model

https://kuleshov-group.github.io/blog/assets/img/ar-diffusion-comparison.png
Two families of generative AI algorithms are widely used today. For continuous data such as images or video, the state-of-the-art approach is based on diffusion models. For discrete data such as text or code, the standard approach is instead autoregressive models. This article explores an alternative for discrete data, one built on the modern paradigm of diffusion. Mainstream language models ...
