EMMA: The 4B Multimodal AI That Outperforms 7B Rivals in Vision & Generation

EMMA: The Most Impressive Unified Multimodal Model of 2025 (And It’s Only 4B Parameters) Every week in 2025, someone drops a new “unified vision-generation” model and claims the throne. Most of them are 7–13B behemoths that eat 4–8k visual tokens per image and still struggle with basic image editing.
