Creating Images with ChatGPT: Guide to AI Image Generation

ChatGPT enables the generation of original images from plain-language prompts, allowing users to produce production-ready assets in minutes by iterating on composition, size, and visual direction. This capability streamlines the process of exploring concepts, communicating ideas visually, and adapting assets for various formats and channels.

Effective Image Prompting Techniques

High-quality image generation is achieved through clear, grounded prompts rather than long or clever phrasing. Effective prompts typically consist of 1–3 clear sentences that define the purpose, main subject, action, location, and visual style.

Grounding Details for Precision

To ensure reliable results, prompts should include specific details regarding:

• Lighting and Texture: Use unambiguous language. For example, "soft natural light from a window on the left" is more effective than "beautiful lighting."
• Layout and Materials: Clarity regarding the specific materials or layout is preferred over vague descriptions.
• Constraints: Direct statements are necessary to prevent unwanted elements. Users should explicitly state if they do not want logos, extra text, or specific visual changes.

Precise Editing and Iteration

When modifying an existing image, the most effective approach is to be explicit about what should change and what should remain constant. A prompt such as "Change only X. Keep everything else exactly the same" provides the clearest guidance for precise edits.

Best Practices for Image Refinement

Improving image quality is best achieved through small, targeted revisions rather than broad reactions. Users should start by establishing the core idea and then adjust one element at a time to prevent the image from "drifting" during the refinement process.

Actionable Adjustments

Users can apply specific feedback to maintain consistency, such as:

• Visual Tone: "Make it brighter" or "tone down the colors."
• Composition and Style: "Simplify the background" or "Keep the same composition, but make the style more modern / softer / more playful."

Advanced Generation Capabilities

Multi-Image Guidance

ChatGPT can use multiple uploaded images to guide generation or editing. To manage this effectively, users should refer to images by their order and explain their relationship. For example, a user might upload a photo of a desk setup (Image 1) and a style reference (Image 2) and request that the style of Image 2 be applied to the layout of Image 1.

When combining elements, the use of clear spatial language (e.g., left, right, foreground, background) is essential for describing relationships between objects.

Rendering Text in Images

Text rendering is most successful when instructions are highly specific. OpenAI recommends the following guidelines:

• Formatting: Put text in quotes or ALL CAPS.
• Detailed Specifications: Specify the font style, size, color, and placement.
• C-Length: Keep text short.
• Spelling: For brand names or uncommon words, spell them out letter-by-letter (e.g., "S-T-R-I-P-E").

Infographics and Dense Layouts

ChatGPT can generate infographics, labeled diagrams, timelines, and posters. For layouts with heavy text or dense information, users should emphasize "sharp text rendering" and may need to perform final polishing in external design tools.

Compliance and Ethical Considerations

Likeness and Permissions

When generating images of real people, users should use reference photos for accuracy and ensure they have obtained the necessary permissions to use those likenesses.

Brand and Product Imitation

To avoid imitation of specific brands, products, or artwork, users are encouraged to request "generic" or "ownable" versions of designs.

Attribution and Policy

Attribution to OpenAI is optional when using generated images. However, all image use must comply with the organization's internal guidelines and OpenAI's usage policies.
