Prompt Guide: GPT-Image-2
GPT-Image-2 is OpenAI's flagship image generation model, designed for production-quality visuals, highly controllable layouts, and complex creative workflows. It excels at high-fidelity photorealism, crisp and readable text, detailed structured layouts (like infographics and deck slides), and exhibits deep world knowledge.
This guide details the prompting techniques required to unlock the full potential of GPT-Image-2 in MindCraft Studio.
1. Prompting Fundamentals
GPT-Image-2 performs best when your prompts are descriptive and follow a clear, logical structure. Rather than using disconnected keywords separated by commas (a "tag salad"), explain how elements in the scene interact.
The Structured Prompting Pattern
When writing complex prompts, organize your instructions in this order:
- Visual Medium & Framing: Define the format (e.g.,
"A 35mm film photograph, close-up shot"or"A flat vector illustration"). - Background & Environment: Describe the setting, atmosphere, and lighting.
- Main Subject: Detail the appearance, pose, clothing, and placement of the subject.
- Key Details & Textures: Add specific visual details (e.g.,
"weathered skin," "soft shadows," "metallic finish"). - Exclusions & Cleanup: State what to avoid at the very end (e.g.,
"no watermarks, no signatures, no extra text").
2. Specificity and Quality Levers
Rather than using generic buzzwords like "photorealistic" or "ultra-detailed," use concrete descriptions to guide the model's output quality.
- For Photorealism: Explicitly include the word "photorealistic" or phrases like "real photograph" or "shot on a 50mm lens." Describe real-world imperfections like
"pores, wrinkles, fabric wear, and subtle skin texture"to prevent the image from looking plasticky or CGI. - Lighting and Composition: Control the mood by specifying light sources (e.g.,
"soft coastal daylight," "dramatic neon lighting," "warm golden hour glow"). Use camera terminology to dictate framing, such as"eye-level perspective," "macro lens," "shallow depth of field,"or"cinematic wide shot." - Iterative Refinement: Start with a simple base prompt, see the output, and then add specific instructions step-by-step to steer the composition rather than overloading the prompt in the first try.
3. Legible Text and Typography
GPT-Image-2 is exceptionally reliable at rendering clear, legible English characters inside images. To ensure typographic accuracy, follow these rules:
- Use Quotes for Exact Text: Wrap the exact words you want to display in double quotes (e.g.,
"THE GREATEST CITY"). - Define Typography Style: Describe the look of the font (e.g.,
"bold white sans-serif lettering," "stylized script," "clean modern typography"). - Control Placement: Specify where the text belongs (e.g.,
"centered near the top," "placed on the product label"). - Spell Out Complex Words: If a brand name or word is uncommon, spell it out letter-by-letter in your description to prevent typos.
- Add a Cleanup Clause: Always append
"no extra text"or"no random characters"to prevent the model from generating gibberish text in other areas.
4. Key Use Cases & Prompts
A. Infographics & Labeled Diagrams
GPT-Image-2 is capable of producing structured visual layouts. To generate infographics or diagrams:
- Treat the prompt like an instructional brief.
- List the specific components and connections you need.
Example Prompt: Create a detailed Infographic of the functioning and flow of an automatic espresso machine. Show the path from the bean hopper, to the grinder, the water tank, the heating boiler, and the group head. Use clean arrows to connect the steps. Make it look like a clean technical explainer diagram with a white background, simple icons, and clear, readable English labels for each component. No watermarks, no extra text.
B. Business Slides & Slideshow Layouts
If you are generating presentation slides or deck layouts:
- Treat the prompt like an artifact specification.
- Explicitly state the data values, charts, and legends.
Example Prompt: Create one pitch-deck slide titled "Market Opportunity" that looks like a clean corporate presentation slide. Use a white background, modern sans-serif typography, and a crisp, minimal layout. The slide must include: a TAM/SAM/SOM concentric-circle diagram in muted blue and gray colors; specific market sizing numbers labeled "TAM: $42B", "SAM: $8.7B", and "SOM: $340M"; and a clean bar chart below showing market growth. Highly readable text, polished spacing, professional design, no decorative clutter.
C. Candid Photorealism
For lifelike human portraits and scenes, describe unposed actions and camera properties.
Example Prompt: A candid photorealistic photograph of an elderly sailor standing on a small fishing boat. He has weathered skin with visible wrinkles, pores, and sun texture. He is calmly adjusting a net while his dog sits nearby on the deck. Shot like a 35mm film photograph, medium close-up at eye level using a 50mm lens. Soft coastal daylight, shallow depth of field, subtle film grain, natural color balance. The image should feel honest and unposed, with real textures and worn materials. No heavy retouching.
D. Clean Logo & Branding Generation
To get clean corporate logos, emphasize flat designs and simplicity:
Example Prompt: Create an original logo for a local bakery called "Field & Flour". The logo should feel warm, simple, and timeless. Use clean, vector-like shapes, a strong silhouette, and balanced negative space. Flat design, minimal strokes, no gradients. Deliver a single centered logo on a plain white background with generous padding. No watermark, no realistic shadows.
E. Multi-Panel Comics & Reels
Describe panels sequentially to create visual stories:
Example Prompt: A vertical comic strip with 4 equal-sized panels. Panel 1: A person walks out of a front door. A pet cat watches from the window. Panel 2: The door clicks shut. The cat turns around inside the quiet house with wide eyes. Panel 3: The cat is happily sprawling across the couch under a warm ray of sunshine. Panel 4: The front door opens, and the cat sits perfectly by the entrance, looking innocent and composed. Clean comic art style, consistent character appearance across panels.
5. Constraints and Negative Guidance
Since GPT-Image-2 does not use a separate negative prompt field in most workflows, control what is excluded directly through negative phrases at the end of your positive prompt:
- To prevent watermarks: Add
no watermark, no signature, no photographer branding. - To ensure clean compositions: Add
plain background, simple backdrop, no clutter. - To avoid text issues: Add
no extra text, no gibberish letters, no random symbols.
