GPT Image 1.5 is OpenAI's image generation model — the same model powering image creation in ChatGPT-4o. It excels at accurate text rendering inside images, image editing with mask-based inpainting, and complex multi-object scenes (10–20 distinct objects). Three quality levels (low/medium/high) let you balance speed and detail. Outputs in PNG, JPEG, or WebP with optional background transparency.

Accurate Text Rendering

Renders legible, correctly spelled text inside images — signs, labels, posters, UI mockups, and book covers without the glitchy text issue.

Image Editing & Inpainting

Edit existing images using mask-based inpainting — replace specific areas, change backgrounds, or add/remove objects while preserving the rest.

Multi-Object Scenes

Generates scenes with 10–20 distinct objects with consistent spatial relationships, accurate details, and world-knowledge integration.
