Summary

SenseNova released a preview of its U1.5 Lite model, showing benchmark gains in image generation and editing, with native 4K output and improved Chinese/English text rendering, though acknowledged weaknesses remain.

SenseNova released U1.5-Lite-Preview Benchmarks: Qwen-Image-Bench from 47.14 to 55.20. ImgEdit-Bench from 3.90 to 4.37. GEdit-Bench-en from 7.47 to 8.17. Key updates: 4K native generation with better texture, material, and lighting detail Improved Chinese and English text rendering for dense layouts like posters and infographics Long, structured prompts with hierarchical constraints work reliably (one example prompt in their docs is ~3,880 Chinese characters covering timelines, color schemes, composition rules, and prohibited elements) Image editing stays localized. Changing one region doesn't shift the rest of the image New workflows: multi-reference composition, style transfer, continuous iterative editing without rerolling Still preview quality. Short prompt understanding, small font rendering, face detail, and aesthetic consistency are acknowledged weaknesses. World knowledge and editing stability in complex scenes also need polishing.
