DiffusionGemma: The Developer Guide- Google Developers Blog

This post introduces DiffusionGemma, an experimental model built on the Gemma 4 backbone, which offers compute-bound parallel generation, bidirectional context and self-correction, and developer-friendly sizes. It details the architecture, including uniform state diffusion and block autoregressive diffusion for variable length generation. The post showcases its ability to solve Sudoku puzzles through parallel denoising and error correction via re-noising. It also provides guidance on serving DiffusionGemma using vLLM and links to resources for downloading weights, learning more, and adapting/fine-tuning the model.
