Can Text-to-Image Models Forget Prompts? Prompt Reinjection Boosts Instruction Following Without Retraining

The paper reveals that multimodal diffusion transformers often lose fine‑grained textual semantics in deeper layers—a phenomenon called Prompt Forgetting—and introduces Prompt Reinjection, a training‑free inference technique that re‑injects shallow text features to markedly improve text‑image alignment and instruction compliance while preserving visual quality and incurring negligible computational overhead.
