Kỹ thuật prompt AI Image 2

Prompt engineering is not a “spell book”—it is turning visual briefs into specs the model can execute. AI Image 2 follows structured instructions well, especially in Thinking mode. This tutorial gives you a reusable BRICK template, text-specific techniques, and 12 industry examples you can adapt immediately.

BRICK five-part template

Every production-grade prompt should include five blocks (order adjustable):

[Brand] Brand and taboos: primary hex, tone, forbidden elements
[Role] Image type: e-commerce hero / poster / UI mockup / comic panel
[Information] Subject, environment, lighting, materials
[Copy] Original text in quotes + font character + placement
[Kinetic] Aspect ratio, resolution tendency, style anchors like "commercial photography" or "flat illustration"

Full example

[Brand] Tech blue #2563EB, no cartoon style, no fake certification badges.
[Role] B2B SaaS launch landscape KV, 16:9.
[Information] Abstract 3D glass forms background, central whitespace, top light, clean.
[Copy] Main headline "Q3 Product Launch", subhead "Live · Oct 15", white sans-serif centered upper area.
[Kinetic] Keynote slide feel, high contrast, text must be readable.

Text rendering: four rules

1. Quote-lock original copy
   Wrong: Write promo headline with discount info
   Right: Main headline “618 Sale”, corner small text “Valid 6.1–6.18 only”

2. Declare mixed scripts separately
   Chinese headline 「Summer Refresh」, bottom-right English "NEW ARRIVAL"

3. Control word count
   Main copy per image: ≤ 20 Chinese characters or ≤ 12 English words; longer copy → image without text + overlay in design software.

4. Specify font character, not exact font names
   Bold sans-serif headline + light body + handwritten style logo area only

How to write negative constraints

AI Image 2 is sensitive to “what not to include”—use a dedicated block:

Do not: watermarks, garbled English, extra fingers, malformed text, competitor logos,
over-HDR, plastic skin, UI frames in corners.

Style lock: Brand Block

Store stable descriptions as a snippet; paste at the top of every prompt:

[Brand Block] Nordic minimal e-commerce; off-white #F5F0EB background; soft light; realistic product scale;
no exaggerated wide-angle distortion; suitable for marketplace hero specs.

When campaigns change SKUs, only edit the product line—the style stays intact.

12 copyable examples (excerpt structure)

1. Marketplace hero 1:1

[Brand Block] …
White electric toothbrush at 45° angle, pure white #FFFFFF background, contact shadow,
no text, commercial product photography, 1:1, ultra sharp.

2. Lifestyle cover 3:4

Portrait 3:4, headline "Weekly Outfit Formula" handwritten style,
four-panel OOTD collage thumbnails, cream tones, magazine layout.

3. Japanese promo banner

Landscape banner, main copy 「夏のセール 最大50%OFF」,
sans-serif Japanese, model in linen dress on right, clear blue sky background.

4. Restaurant menu board

Chalkboard menu style, Thinking mode,
list 6 dish names and prices (full list in quotes),
