How to write better Hunyuan Image prompts

Hunyuan Image responds best to a short, complete paragraph that reads like a creative brief. This guide shows the structure that works, how to get exact words into an image, and how to make a single targeted edit.

In short

  • Order matters: subject, composition, light, material, finish.
  • Put exact in-image words in double quotes and name the typeface style and placement.
  • For edits, describe one change and list what must stay the same.
  • Use the Instruct route for long, detailed briefs and typography-heavy layouts.

The paragraph structure

Write the deliverable first ("editorial product photograph", "exhibition poster"), then the subject, then where things sit in the frame, then the light, then materials and finish. One paragraph of 30–60 words is usually enough; lists of disconnected tags tend to produce generic results.

Example · product photograph
Editorial product photograph of a translucent amber glass carafe on a travertine ledge, one dried fig branch beside it, low afternoon sun from the left casting a long soft shadow, warm neutral palette, shallow depth of field.

Getting exact text into the image

Quote the words exactly and say where they go and how they should look. Keep headlines short; long sentences are more likely to drift. The Hunyuan Image 3.0 Instruct route is tuned for this kind of typography.

Example · poster
Exhibition poster with the exact headline "QUIET HOURS" in a tall condensed serif, deep teal on ivory, wide margins, a single folded paper crane centred below the headline, minimal composition.

Making one clean edit

Choose the Edit route, upload an image you have permission to use, and ask for one change. Naming what must not change protects the rest of the picture.

Example · edit instruction
Change the background to a pale stone wall. Keep the carafe, the fig branch, the camera angle and the afternoon light exactly as they are.

Common problems and fixes

  • Busy, unfocused result: remove adjectives that compete; keep one light source and one palette.
  • Wrong layout: describe positions explicitly — "centred", "lower third", "left edge".
  • Garbled lettering: shorten the quoted text and switch to the Instruct route.
  • Edit changed too much: repeat the "keep" list and ask for a smaller change.

Frequently asked questions

Should I write prompts in English?

English briefs work reliably. Keep quoted in-image text in the exact language and spelling you want to see.

Which aspect ratios can I use?

1:1, 16:9, 9:16, 4:3 and 3:4 are available in this workspace.

Does this guide apply to Hunyuan Image 3.5?

The same brief structure applies. Hunyuan Image 3.5 adds more references and multi-round context, which makes the "one change at a time" approach even more effective once its route is connected.
