Kromoss Prompt Generator

Free · No sign-up · Runs entirely in your browser

The Kromoss Prompt Generator builds natural-language prompts for the Kromoss image model, a full fine-tune of MOSS-Image-Base that produces sharper, more detailed images. Describe your subject, choose styles and lighting, add a text string to render, and the tool assembles a prompt following Kromoss best practices. Everything runs locally in your browser; nothing is uploaded.

How to Write Better Kromoss Prompts

  1. Put rendered text in quotes. Use exact wording you want to appear, e.g., "KROMOSS" so the model can focus on rendering it legibly.
  2. Negative prompts need CFG above 1. Turbo LoRA (CFG 1) ignores negative branches — switch to Full model to use them.
  3. Turbo LoRA = 8 steps CFG 1 for speed. Use for quick iterations; Full model gives higher quality with negatives.
  4. Native 1024px — keep aspect multiples of 16. The model prefers dimensions divisible by 16 for cleaner generation.
  5. English prompts recommended. Clear, descriptive language produces more reliable results.
  6. Drop-in ComfyUI replacement for moss_image_sft_bf16.safetensors. Same loader files — just swap in kromoss_bf16.safetensors; with the LoRA use KSampler euler/simple, 8 steps, CFG 1.
