Mastering Prompts for GPT-4o Image
Prompting is crucial in all modes, but the focus shifts depending on whether you are creating, editing, or customizing. GPT-4o models are known for strong prompt interpretation and respond well to descriptive, clear language.
Prompt Writing Basics: Subject, Context, and Style
A good starting point for any prompt is to define the core elements:
Subject
The main object, person, animal, or scenery.
Context/Background
The environment or setting for the subject.
Style
The artistic style (e.g., painting, photograph, sketch, or more specific styles).
After establishing these basics, refine your prompt by adding more details through iteration until the generated image aligns with your vision.
General Prompting Principles:
Be Specific and Detailed
Be Specific and Detailed
Employ descriptive language, detailed adjectives, and adverbs to paint a clear picture for Imagen. Example: Instead of “a park,” try “A park in the spring next to a lake, the sun sets across the lake, golden hour, red wildflowers.”
Use Natural Language
Use Natural Language
Formulate prompts using descriptive sentences, as you would describe an image to another person.
Consider Negative Prompts
Consider Negative Prompts
Use negative prompts to steer away from unwanted elements (Note: support varies by model).
Prompt Enhancement
Prompt Enhancement
For models supporting prompt enhancement (like imagen-3.0-generate-002), a shorter prompt can be automatically expanded for potentially better results. This is enabled by default.
Prompting for Specific Modes/Tools:
Create Mode
Create Mode
Focus on fully describing the desired image from scratch, combining subject, context, and style with rich details. Example: “A futuristic cityscape at sunset, high angle view, digital painting, vibrant colors.”
Edit Mode (Draw Mask)
Edit Mode (Draw Mask)
Describe what you want to appear within the masked area. Focus on the object or scene you want to generate and how it should blend with the existing image. For best results, use a description of the masked area. Avoid single-word prompts. Example: (Mask over a blank wall) Prompt: “A vibrant graffiti mural covering the wall.”
Edit Mode (Maskless Editing)
Edit Mode (Maskless Editing)
Describe the desired changes to the image in natural language. The AI will interpret your instructions and apply the edits without a mask. Example: (Input Image: Photo of a car) Prompt: “Change the car to red.”
Edit Mode (Reference Images)
Edit Mode (Reference Images)
Describe the desired image, indicating how the AI should draw inspiration from the reference image(s). You can reference specific images if using multiple. Example: (Reference Image 1: A character, Reference Image 2: A scene) Prompt: “Generate a portrait of the person from image1 standing in the setting from image2.”
Edit Mode (Outpainting)
Edit Mode (Outpainting)
Describe the content you want to appear in the expanded areas around the original image. You can provide an empty string to create the edited images, but a description of the masked area is recommended for best results. Example: (Outpainting around a portrait) Prompt: “A lush forest extending around the person.”
Edit Mode (Product Image)
Edit Mode (Product Image)
Describe the desired background or environment for the product. Example: (Input: Product image) Prompt: “Place the product on a wooden table in a sunny cafe.”
Customize Mode (Subject)
Customize Mode (Subject)
Describe the desired image, referencing the subject from your input image. Use the format [referenceId] to refer to the subject image(s).
Example: (Input: Subject Image with referenceId 1) Prompt: “Generate an image of the person [1] as a knight in shining armor.” (Referencing the subject with [1]).
Customize Mode (Style)
Customize Mode (Style)
Describe the desired image content, indicating it should be in the style of your input image. Use the format [referenceId] to refer to the style image.
Example: (Input: Style Image with referenceId 1) Prompt: “Generate an image of a cat sitting on a chair in the style of image [1].”
Customize Mode (ControlNet)
Customize Mode (ControlNet)
Your prompt describes the content and style of the image, while the ControlNet image provides the structural guide. Ensure your prompt aligns with the structural guidance (e.g., edges, pose) provided by the ControlNet image. Example: (Input: Control Image - Canny edges of a building) Prompt: “A beautiful watercolor painting of an ancient castle at sunset.”
Advanced Prompting Techniques:
Generating Text in Images
Generating Text in Images
GPT-4o can add text to images.
- Iterate: You may need multiple attempts to get the desired text appearance and placement.
- Keep it Short: Limit text to 25 characters or less.
- Multiple Phrases: Experiment with 2-3 distinct phrases.
- Guide Placement: While placement can vary, you can attempt to guide it in the prompt.
- Inspire Font Style/Size: Specify general font styles or size indications (small, medium, large). Example: “A poster with the text ‘Summerland’ in bold font as a title, underneath this text is the slogan ‘Summer never felt so good’.”
Prompt Parameterization
