GPT Image Online is a browser-based AI image generation and editing tool powered by the GPT Image model, with the current version being GPT Image 2. Its distinguishing feature is that it understands prompts through natural language conversation, and it can be used to generate realistic portraits, vector illustrations, 4K posters, editable UI mockups, infographics, and more.
Main capabilities
- Text rendering within images: It can write clear, readable text into images, suitable for posters, product labels, social graphics, and UI mockups.
- Precise editing: After uploading a reference photo, describe the changes in natural language, and the model rewrites only the specified parts while maintaining consistency in facial features, lighting, and composition across multiple rounds of editing.
- Built-in world knowledge: The model can recognize the appearance of specific things such as MacBooks, Tesla Cybertrucks, and Renaissance paintings, reducing detail errors.
- Multi-style support: A single model covers styles such as realistic, 3D, anime, illustration, vector, and data visualization, with a maximum resolution of 4096×4096.
- Text-to-image and image-to-image: Supports starting from a blank prompt, a reference photo, or a masked area, covering inpainting, variations, and style transfer.
- Multi-round editing: GPT Image 2 maintains visual consistency across more than five rounds of editing.
How to use
- Write a prompt describing the scene, subject, and the text you want to appear in the image.
- Optionally upload a reference image, such as a product photo, avatar, or mockup, and mask the area to be modified.
- Choose quality (low/medium/high) and aspect ratio (square, portrait, landscape).
- Download and iterate; results are returned in about 5 to 8 seconds, and all rendered results are saved in My Creations for 7 days.
Use cases
- Product photography: Generate lifestyle scenes without a studio, and change backgrounds, color schemes, and seasons.
- Social and advertising: Generate Instagram carousels, TikTok covers, YouTube thumbnails, and paid ad creatives with real copy.
