GPT-Image 1.5 is OpenAI’s latest flagship AI image generation and editing model. It deeply follows natural language instructions, preserving key visual details in edits, and integrating both text and image inputs into a unified generative workflow. Designed for professional creative pipelines and rapid iteration, GPT-Image 1.5 delivers production-ready visuals with strong instruction adherence, precise local edits, enhanced detail retention, and significantly accelerated generation times.
Key Features
-
Text-to-Image Generation
- GPT-Image 1.5 generates high-quality visuals directly from natural language prompts.
-
Image Editing & Transformations
- Supports sophisticated text-driven editing of existing images. Users can request targeted edits that alter specific features while preserving other parts of the image.
-
Multi-Image Inputs
- Allows multiple input images for composite workflows or cross-reference styles. You can combine elements from several sources in a single output.
-
Text Rendering
- Text generation inside images supports legible typography, signs, labels, and logos.
-
Background Rendering Control
- Supports explicit control over background rendering, allowing images to be generated with either fully opaque backgrounds or transparent backgrounds (alpha channel).
-
Quality Tiers
- Provides explicit quality control via a dedicated quality parameter (Low, Medium, High). This enables developers and creative teams to intentionally balance generation speed and visual fidelity.
Technical Capabilities
- Modalities: Text to Image, Image to Image
- Native Outputs: 1K, 2K, and 4K image generation.
- Flexible Ratios: 1:1, 3:2, 2:3
- Backgrounds: Opaque or Transparent
- Quality: Low, Medium, or High
- Max input image:6
- Max output image:1
Best Use Cases
Creative Content & Storytelling: Ideal for generating concept art, detailed scenes, character work, and narrative visuals with high fidelity and precise prompt adherence.
Photo Editing & Refinement: Apply natural language edits ranging from style changes to selective transformations without needing manual graphic tools.
Marketing & Branding Assets: Produce professional images for campaign visuals, product mockups, posters, infographics, and promotional content with controlled text and compositional clarity.
Strengths and Limitations
Strengths
- High Fidelity & Prompt Alignment: Delivers visually rich images that closely follow prompt instructions.
- Context & Intent Awareness: Multimodal reasoning interprets creative brief intent, reducing the need for iterative prompt engineering.
- Speed & Workflow Efficiency: Generates images significantly fast. Enabling rapid iteration and creative exploration.
Limitations
- Crowded Faces & Complex Scenes: Maintaining consistent depiction across many faces or objects can occasionally produce errors.
Tips for Better Prompts
- Describe Intent, Not Just Keywords: Use full descriptions of subject, environment, style, mood, and purpose
- Use Sequential Instructions for Complex Edits: Guide the model stage-by-stage when performing elaborate transformations or layer-based edits.
- Specify What Should Be Preserved: For edits, explicitly state which elements are unchanged to maintain compositional integrity.
