Direct answer: In Flux Art, choose GPT Image 2. Structure your prompt in three separate parts — put the "copy text" in quotation marks, state the "layout position" as its own sentence, and state the "style" as another sentence. For quality tier, use the medium tier for everyday use. This keeps Chinese text crisp (no garbled characters) and keeps the copy from covering the product. Just copy the template in Section 3 below.
I. Why GPT Image 2 for Hero Images With Text
The most common way a hero image fails isn't image quality — it's Chinese text: most models drop strokes or garble characters when rendering Chinese. GPT Image 2's strength is exactly text rendering and layout, and it also holds up well on realistic details like metal reflections and fabric wrinkles — a promo hero image needs both "the photo to look real" and "the text to be clear," and it handles both. Inside Flux Art it's labeled for 4K output and is ready for commercial use (no watermark; commercial usage rights are subject to the official site's current terms).

II. How to Choose Among the 12 Precision × Resolution Tiers (the Key to Saving Credits)
GPT Image 2 in Flux Art offers 3 precision tiers × 4 resolution tiers = 12 combinations. The rule in one line: low tier for thumbnails, medium tier for hero images, high tier for detail shots.
| Image Type | Recommended Combination | Reason |
|---|---|---|
| Test shots / A-B drafts | Low precision · low resolution | Fast direction screening, cheap |
| Listing hero image | Medium precision · medium/high resolution | Balances look and cost |
| Detail close-up / KV | High precision · high resolution | Trust-building asset, worth the spend |
Per-image credit cost is subject to the official site/console's current rates; testing composition on the low tier first, then moving to the high tier once you're satisfied, is the most economical path.

III. Prompt Template: Separate Copy, Layout, and Style Into Three Parts
① Standard Promo Hero Image
```text
Generate an e-commerce promo hero image, 1:1. Subject: [black wireless Bluetooth earbuds], placed on [a light gray matte countertop].
Leave the top 1/5 blank for the headline. Headline copy: "Limited-time new arrival", sub-copy: "20% off the 3rd item".
Style: bright and clean, e-commerce promo feel, crisp text, not covering the product.
```
```text
EN skeleton: e-commerce promo hero, 1:1. Subject [product] on [background].
Headline "..." in the top 1/5, sub-copy "...". Bright clean commercial style,
crisp text, never covering the product.
```
② Vertical Content Image (3:4)
```text
Generate a 3:4 e-commerce content image. Subject: [product + a one-line usage scenario].
Place one line of copy in the bottom 1/6: "[short selling-point phrase]". Lifestyle lighting, text small and crisp.
```
Writing tips: always put the copy in quotation marks; describe position with actionable phrasing like "top 1/5" or "bottom 1/6"; only edit the content inside the quotes each time and leave the layout sentence untouched — this keeps consistency highest when batch-generating images.
IV. Prohibited Superlatives: Blocklist and Replacements
| Don't Put in the Image | Replace With |
|---|---|
| Lowest price ever / lowest on the whole internet | Limited-time price drop |
| No. 1 / best-seller champion | Restocked hot seller / fan favorite |
| Best to use / top-tier | Tested and proven / flagship model |
| 100% effective / absolute | Describe the specific function instead |

V. Fixing Mistakes: Inpainting, Not Full Regeneration
Typos, price changes, wanting to edit the sub-copy — use inpainting to paint over just the text area, with a prompt like "change the text to: '[new copy]'", leaving the product and layout untouched. Compared to regenerating the whole image: more consistent, lower cost, and cleaner variables when running Taobao Ads (Zhitongche) A/B tests.
VI. Find Your Match: Which Type Is Your Hero Image
| Your Scenario | The Most Painful Step | How to Do It in Flux Art | Recommended Primary Model |
|---|---|---|---|
| Big-sale hero image with text | Garbled Chinese, prohibited superlatives | Write copy in quotes + self-check against the blocklist | GPT Image 2 |
| Everyday new-arrival hero image | Generation cost | Batch-generate at medium precision, medium resolution | GPT Image 2 |
| White background + promo copy, both needed | Hassle of switching tools | Generate the white background first, then add text | Nano Banana 2 + GPT Image 2 |
| Vertical content image | Re-laying out the composition | Recompose at 3:4, don't crop | GPT Image 2 |
A hands-on log: while test-running a big-sale hero image for a pair of Bluetooth earbuds, the first version crammed the entire line "Limited-time new arrival, 20% off the 3rd item" into the main headline, and the text came out cramped and small; splitting it into a main line and a sub line and regenerating fixed the clarity right away. Later, wanting only to change "20% off" to "30% off," inpainting the text area took thirty seconds, with the layout and product completely untouched. Three takeaways: keep copy short, split main and sub lines, and use inpainting for text edits.
