DiffusionGemma: 4x faster text generation

DiffusionGemma is an experimental open AI model that uses text diffusion (a method that generates multiple words at once instead of one at a time) to achieve up to 4x faster text generation on GPUs compared to traditional language models. Unlike standard LLMs that predict words sequentially, DiffusionGemma generates entire blocks of 256 tokens in parallel, making it useful for speed-critical tasks like real-time editing and code completion, though with lower output quality than standard models.
