Why we included this project
Vague prompts are the usual culprit when text-to-image output misses the mark, and PromptEnhancer tackles that problem before the generation model ever sees your words. Built by Tencent Hunyuan's research team, it runs a chain-of-thought rewriting model behind a small Python API, so you can drop it into a pipeline and get more consistent images without hand-tuning every prompt. An image-editing mode also uses the source image as visual context to tighten editing instructions, and quantized GGUF checkpoints let the whole thing run on a single consumer GPU rather than a big cluster. The repo ships the 7B model and an evaluation dataset, which helps if you want to compare rewriting quality on your own workloads. It is a self-contained component, not a framework, so the real question is whether the extra preprocessing step earns its place in your generation stack.
