Google’s new open model DiffusionGemma generates text from noise instead of word by word

Google released DiffusionGemma, a 26-billion-parameter model that generates text not token by token but through diffusion, similar to how image AI turns noise into a picture. According to Nvidia, it hits about 1,000 tokens per second on a single H100 GPU, roughly four times faster than comparable autoregressive models.

The speed comes at a cost, though. Output quality is lower, so Google is positioning it as an experimental tool for developers for now.
