ByteDance research improves image generation with structured prompts

jiqizhixin · x · 2026-08-21

ByteDance Seed researchers found that naively adding text to prompts hurts performance in models like Qwen-Image and FLUX.1. They introduced a structured-prompt schema incorporating image-grounded facts (geometry, semantics) instead of filler prose.

Scaling laws indicate diffusion loss decreases linearly with information density, not token count. The system beats all open-weight models on compositional and reasoning benchmarks, matching top closed-weight models. The secret is a finetuned prompter trained via verifier-gated distillation. Code, models, and demo are available.
