FAQ
How does this prompt generator work?
We use a language model fine-tuned for image description. It analyzes your short request, fills in missing details like lighting, composition, materials, and camera perspective, then outputs an English prompt aligned with Flux best practices.
Which input languages are supported? What language is the output?
Input: Chinese and English are fully supported, including mixed input.
Output: The final optimized prompt is always in English to maximize quality across AI image platforms, especially Flux.
Is it usable for Midjourney or Stable Diffusion?
Yes. While optimized for Flux, the prompt structure includes subject, environment, lighting, and style details that work well for Midjourney v6 and Stable Diffusion (SDXL/SD1.5).
Is there a length limit for the generated prompt?
For input, we recommend staying under 500 characters for best understanding. Output is kept within the optimal Flux token range, usually 50–150 English words, to avoid dilution.
