What is FLUX.1 Schnell?
FLUX.1 Schnell ("schnell" is German for fast) is a 12-billion-parameter text-to-image model from Black Forest Labs, released under the Apache 2.0 license. It is distilled to generate an image in one to four steps, which makes it much faster than the larger FLUX models.
On ImgAI it is free within a daily quota and also available to visitors who have not signed up; the creator shows how many free images remain today. It takes text only (no reference images) and offers 5 aspect ratios. You can write prompts in any language: they are translated into English automatically before generation, since the model understands English best.

FLUX.1 Schnell prompt tips
These come from real generations — read them alongside the original prompts in the examples.
Keep prompts short and visual
One sentence that names subject, setting, light and style works well. Long instructions are partly ignored.
Lead with the subject
Put the main subject first: "Modern glass house in a pine forest, morning fog".
Avoid text in the image
Schnell is not built for typography. For posters with words, use GPT Image 2 or Nano Banana Pro.
Graduate good prompts
When a draft works, paste the same prompt into FLUX.2 or Nano Banana 2 for a sharper, higher-resolution version.
