# SenseTime open-sources 8B multimodal model with native 4K image output

SenseTime has open-sourced SenseNova U1.5 Lite, an 8-billion-parameter multimodal model designed to combine visual understanding, image generation and editing in one system. The model supports native 4K image output and is designed to handle constraints involving subjects, counts, spatial relationships, text, layouts and visual styles.

The company says the lightweight model improves identity preservation and spatial structure during editing, while adding controls such as bounding boxes, visual markers and multiple reference images. SenseNova U1.5 Lite is available through GitHub, Hugging Face and ModelScope. \[\[IT Home, in Chinese\]
