How to Prompt GPT Image 1.5: Text-to-Image?

GPT Image 1.5 processes prompts differently from diffusion-based models. Because it uses a multimodal reasoning engine, it responds to context and intent rather than just visual descriptors. The following prompting principles will help you get more accurate outputs from the model.

Be Specific About Context, Not Just Appearance

GPT Image 1.5 understands the world, e.g., cultural contexts, historical periods, physical environments, and domain-specific settings. Rather than describing what something should look like, describe what it is and where it exists, and let the model's reasoning handle the visual interpretation.

Describe Spatial Relationships Explicitly

GPT Image 1.5 handles spatial reasoning well, but it performs best when spatial relationships are stated explicitly rather than left to interpretation. When composing a scene with multiple elements, describe where each element is positioned relative to the others.

• State the primary subject and its position in the frame first — centre frame, left third, foreground, background
• Describe secondary elements in relation to the primary subject — to the left of, behind, in the lower right corner of
• Specify camera perspective where relevant — eye level, looking up from below, overhead bird's-eye view, three-quarter angle

Include Lighting and Atmosphere Deliberately

GPT Image 1.5 understands physical lighting accurately and will render it correctly when specified. Lighting descriptions improve output quality significantly for commercial and professional photography styles:

• Specify light source and direction — soft window light from the left, overhead studio strobe, warm golden hour backlight
• Describe the quality of light — hard shadows, soft diffused light, dramatic contrast, flat, even lighting
• Include atmospheric context where relevant — hazy morning mist, clear noon sunlight, overcast diffused daylight

Prompts for Text Rendering

GPT Image 1.5 generates legible, correctly spelled text within images. When your prompt requires text to appear in the image, include the exact text in quotation marks within the prompt description:

• "A minimalist poster with the headline 'Less is More' in large black sans-serif type on a white background, with a single thin horizontal rule below the headline and a small subtitle reading 'Annual Design Conference 2026' in 12pt grey font."

• "A product label for an artisan coffee bag reading 'Dark Roast Single Origin Ethiopia' in a clean serif font at the top, with tasting notes listed below in two lines: 'Notes of dark chocolate, dried cherry, and brown sugar' in smaller body copy"

• "A UI card component showing a user profile with the name 'Sarah Chen' in bold, the title 'Product Designer' below in grey, and three stat labels reading Followers: 2.4k, Projects: 18, and Reviews: 94 in small caps"

How to Use GPT Image 1.5 for Image Editing?

GPT Image 1.5's image-to-image editing capability helps you to modify specific elements of an existing image using natural language instructions while preserving everything else. This is one of the model's strongest features and produces meaningfully different results from models that regenerate the entire scene when an edit is applied.

Writing Effective Edit Instructions

Edit instructions for GPT Image 1.5 work best when they are specific about what is being changed and clear about what must remain unchanged. The model preserves composition, lighting, and style by default, but explicitly stating what to keep helps anchor the edit to the right region:

How To Use GPT Image 1.5 for Multi-Turn Editing Workflow?

GPT Image 1.5 supports multi-turn editing, where successive edits are applied to the same image across multiple instructions. The model maintains visual quality and coherence across turns, making it suitable for iterative refinement workflows where a final output is reached through a series of incremental changes rather than a single large edit.

A practical multi-turn editing workflow for a product photography use case might look like this:

1. Start with the base product image and instruct: "Place the product on a light oak wood surface with soft diffused studio lighting from above."
2. Review the output and refine: "Slightly warm the colour temperature of the lighting. Add a subtle reflection of the product on the wood surface."
3. Final polish: "Sharpen the product label detail and slightly increase the contrast on the product surface to make the material texture more visible."

For teams building multi-turn editing into a structured production workflow, the ImagineArt AI Workflow system supports node-based pipelines that chain generation and editing steps into a repeatable, automated sequence.

How to Use GPT Image 1.5 for Inpainting?

Inpainting allows you to modify a specific region of an image through a natural language instruction while leaving everything outside that region completely unchanged. This is more targeted than image-to-image editing and is particularly useful for precise single-element changes within a complex composition.

On ImagineArt, the inpaint tool is accessible through the edit suite. Upload your image, identify the region you want to modify, and provide a clear instruction describing what the modified region should contain. GPT Image 1.5 executes the inpaint while maintaining the style, lighting, and visual consistency of the surrounding area.

The most common inpainting use cases where GPT Image 1.5 performs reliably include replacing a product background in an e-commerce image, removing a specific unwanted element from a scene without affecting adjacent elements, adding an object that integrates naturally into the existing lighting environment, and updating text or label elements within a product or packaging visual.
