Google quietly posted DiffusionGemma 26B, a diffusion-based open multimodal Gemma.

Google's HF org lists diffusiongemma-26B-A4B-it (~4B active), an image-text-to-text Gemma member that's diffusion-style rather than purely autoregressive (Hugging Face). No detailed announcement yet, which is why I'm flagging it low. But a diffusion approach inside the Gemma open family is an architecture signal worth tracking if you care about where open multimodal generation goes next.
