Your promo lock is tonight. You paste "30% OFF — Shop Now" into a generic image model and the headline garbles before trafficking. ChatGPT Image 2 (GPT Image 2 on KreadoAI) fixes that when prompts treat copy as a layout constraint — not an afterthought.
Most SERP results still demo consumer ChatGPT apps or list model benchmarks. Few give performance teams a repeatable prompt system for offer-led statics: exact strings in quotes, ratio locked, QA at feed scale. This gpt image 2 prompt guide uses the OCAL Stack — Offer, Composition, Alignment, Layout — tested on KreadoAI in June 2026 across beauty, supplements, and home DTC briefs.
Below: conversion-first principles, engineered prompt structure, category templates, and copy-paste briefs you can run in GPT Image 2 for Ads today.
1. Core Principles: Prompt for Conversion
Ad prompts are not art direction exercises. Every line should support three priorities:
Lock the Offer First
GPT Image 2 renders in-frame headlines, price badges, and CTAs when you spell them exactly. Put every customer-facing string in double quotes. Keep headlines under ten words when possible — longer copy occasionally drops a character at feed scale.
Design for Thumb-Stop Layout
You have one scroll, not a gallery visit. The frame should:
- Place product and offer block in separate zones
- Keep the headline above the fold on 1:1 and 4:5 crops
- Reserve bottom 12–15% for CTA bar on 9:16 Stories layouts
Lead with the selling point that closes the click — discount, bundle price, or free-shipping hook.
Treat Typography as a Hard Constraint
Add explicit tags: "sharp readable typography", "no warped letters", "no extra logos". GPT Image 2 responds better to layout nouns — "structured DTC ad layout", "split panel promo" — than mood adjectives alone.
2. The OCAL Stack: Engineered Prompt Structure
On KreadoAI, strong GPT Image 2 prompts are structured briefs — not one-line vibes.
OCAL refers to four layers you write in order:
| Layer | What to specify | Example fragment |
|---|---|---|
| Offer (O) | Headline, price, CTA, disclaimer | headline text "20% OFF TODAY", bottom CTA bar "Shop Now" |
| Composition (C) | Product placement, background, props | serum bottle left third, clean clinical marble surface |
| Alignment (A) | Ratio intent, safe zones, text zones | 1:1 Meta feed layout, headline top-right, CTA bottom bar |
| Layout (L) | Structure template + quality floor | structured DTC ad layout, photoreal product, no extra logos |
Recommended writing order:
- Paste exact offer strings in quotes (Offer)
- Anchor product position and scene (Composition)
- Name ratio and zone rules (Alignment)
- Close with layout type and quality tags (Layout)
Weak prompt: "A stylish skincare ad with a discount — looks premium."
Strong prompt (OCAL):
Skincare serum bottle left third on marble surface (Composition). Headline text "20% OFF TODAY" top right, subhead "Vitamin C · 30ml", bottom CTA bar "Shop Now" (Offer). 1:1 Meta feed layout, headline clears top safe zone, CTA bar bottom 12% (Alignment). Structured DTC ad layout, photoreal product, sharp readable typography, no extra logos (Layout).
3. Copy-in-Image Writing Rules
GPT Image 2 (ChatGPT Images 2.0) earns credits when copy lives inside the frame. These rules cut regen cycles:
Quote Every Trafficking String
Headlines, prices, promo codes, and CTAs must appear inside double quotes in the prompt. Match your trafficking sheet character-for-character — including capitalization and punctuation.
Separate Primary and Secondary Copy
Use distinct labels: headline text, subhead, price badge, disclaimer block, bottom CTA bar. The model maps zones more reliably than a single comma-separated sentence.
Shorten Before You Regenerate
If a headline garbles, shorten it before changing models. Twelve-plus word headlines miss characters more often than eight-word hooks.
Add Compliance Layers Explicitly
For supplements and regulated categories, name the disclaimer block: disclaimer text "These statements have not been evaluated by the FDA" bottom left, small legible type.
OCAL Stack maps offer strings to layout zones — quote every trafficking line before you generate.
4. Category Prompt Templates
Use these as starting briefs on KreadoAI AI Image Generator (/ai/image-generator?model=gpt-image-2). Swap brand nouns and quoted strings per SKU.
Beauty / Skincare — Flash Promo · 1:1
Rose-glass serum bottle left third on soft peach gradient (Composition). Headline text "30% OFF", subhead "Vitamin C Serum — Limited Time", circular price badge "$24.99", bottom CTA bar "Shop Now" (Offer). 1:1 Meta feed layout, product never overlaps headline block (Alignment). Clean beauty DTC ad layout, photoreal bottle, sharp readable typography, gold accent on cap, no extra logos (Layout).
Supplements — Compliance + Offer · 4:5
Amber probiotic jar center-right on sage green gradient (Composition). Headline text "Buy 2 Save 15%", price badge "$29.99", disclaimer text "These statements have not been evaluated by the FDA" bottom left small type, bottom CTA bar "Add to Cart" (Offer). 4:5 vertical feed layout, disclaimer legible at mobile width (Alignment). Wellness DTC structured layout, photoreal jar, sharp readable typography, no extra logos (Layout).
Home / Living — Bundle Offer · 9:16
Three ivory candles on linen surface, centered product stack (Composition). Headline text "3 FOR $45" top center, subhead "Hand-poured · Free Shipping", bottom CTA bar "Shop Now" (Offer). 9:16 Stories layout, top 15% clear for platform UI overlay, CTA bar bottom 12% (Alignment). Home goods promo layout, warm natural light, sharp readable typography, no extra logos (Layout).
Fashion DTC — Flash Sale Split · 1:1

Headline text "FLASH SALE" on burgundy panel, large callout "40% OFF", subhead "Ends Midnight", bottom CTA bar "Shop Now" (Offer). 1:1 feed layout, high contrast white type on burgundy (Alignment). Fashion e-commerce promo layout, sharp readable typography, no extra logos (Layout).
5. Style and Lighting Reference
| Dimension | Keywords | When to use |
|---|---|---|
| Background | clean clinical, soft gradient, marble surface, minimal studio | Beauty and wellness promos |
| Lighting | soft diffused, rim light, natural window light | Product clarity without harsh glare |
| Mood | premium DTC, clinical trust, warm lifestyle | Match category compliance tone |
| Quality floor | photoreal product, sharp focus, sharp readable typography | Every ad brief — non-negotiable |
| Hard limits | no extra logos, no warped text, no duplicate headlines | Append to every Layout line |
6. Worked Example: Skincare Flash Promo
Reference setup:
- Product reference image uploaded (serum bottle pack shot)
- Ratio: 1:1 Meta feed
- Trafficking sheet headline: "20% OFF TODAY"
Full OCAL prompt:
Reference product bottle shape from uploaded image (Composition). Frosted glass serum bottle left third on white marble, soft peach accent gradient behind copy block. Headline text "20% OFF TODAY" top right bold, subhead "Vitamin C · 30ml", bottom CTA bar "Shop Now" (Offer). 1:1 Meta feed layout — headline and price never overlap product silhouette, CTA bar spans bottom 12% (Alignment). Structured skincare DTC ad layout, photoreal product, sharp readable typography, no extra logos, no warped letters (Layout).
Constraint tags to append on regen: fix headline spelling only · keep product position · increase headline weight.
Expected QA pass: headline readable at 1080×1080 mobile feed width, CTA bar intact, no extra brand marks.
7. Universal Prompt Template
Copy and fill brackets before each generate session:
[Product description + position] on [background/scene]. Headline text "[EXACT HEADLINE]", [subhead/price badge/disclaimer as needed]. [Ratio] layout — [safe zone rules]. [Layout type] ad layout, photoreal product, sharp readable typography, no extra logos.
Quality floor line (always include): no warped text, no duplicate headlines, no watermarks, no competitor logos.
Extend winning 1:1 layouts across 4:5 and 9:16 via Multi-Size Ad Image Generator — generate ratio before render; post-crop often breaks copy block alignment.
8. Pre-Generation Checklist
Before you hit Generate on KreadoAI:
- Every trafficking string is in double quotes
- OCAL four layers are present (Offer → Composition → Alignment → Layout)
- Ratio intent is named (1:1, 4:5, or 9:16)
- Headline is ≤10 words or split into headline + subhead
- Quality floor tags are appended
- Product reference uploaded when pack shot geometry matters
One regen is normal when a subhead wraps awkwardly. Fix copy length before switching models.
9. Why KreadoAI + GPT Image 2
Together, KreadoAI and ChatGPT Image 2 let performance teams:
- Ship offer-led statics without a Canva text pass on every variant
- Export 1:1, 4:5, and 9:16 from one brief
- Batch promo variants beside Nano Banana and Seedream in one wallet
- QA copy spelling at feed scale before Meta Ads Manager upload
Structured prompts are one of the highest-leverage steps in AI ad creative — the bottleneck shifts from design turnaround to brief quality.

FAQ
What is the best gpt image 2 ad creative prompt?
Put exact headline, price, and CTA strings in quotes, name layout structure (product left, copy right), specify ratio intent, and add "sharp readable typography, no extra logos." The OCAL Stack — Offer, Composition, Alignment, Layout — covers all four layers in order.
How is this different from the ChatGPT app for images?
The consumer ChatGPT path is not built for ad ratio exports or trafficking QA. KreadoAI GPT Image 2 for Ads locks 1:1, 4:5, and 9:16 presets and sits beside Ad Creative Generator for batch variants.
Can GPT Image 2 render long disclaimers in ads?
Yes — name a disclaimer block explicitly with small legible type. Supplements and regulated categories perform better than stylized models when compliance copy must survive feed-scale QA.
GPT Image 2 vs Nano Banana 2 for prompts?
GPT Image 2 prompts center on in-frame copy accuracy. Nano Banana 2 prompts center on pack-shot fidelity and SKU geometry when copy lives in ad primary text. Most teams maintain both brief templates.
How many words should a GPT Image 2 headline be?
Aim for eight to ten words in the headline. Move secondary details to a subhead or price badge. Longer strings occasionally drop characters — shorten before regenerating.
Do I need a product reference image?
Recommended when bottle shape, cap color, or packaging geometry must match the SKU. Optional for abstract promo layouts where the offer block is the hero.
