GPT Image 1.5
OpenAI's flagship image generation model featuring precise editing, face preservation, and 4x faster generation speeds.
OpenAI Fast image generation with precise editing and face preservation
GPT Image 1.5 is an image generation model developed by OpenAI and released in December 2025. It serves as the engine behind the ChatGPT Images experience and is also available to developers via the API using the model ID gpt-image-1.5. The model supports both text-to-image generation and image editing, with output resolutions up to 1536×1024 and 1024×1536 pixels. It ranks first in the Image Edit category on the Chatbot Arena leaderboard.
The model is designed to follow nuanced editing instructions, changing only the specified elements of an image while preserving lighting, composition, and overall context. It maintains consistent facial likeness across inputs, outputs, and sequential edits, making it well-suited for photo retouching, virtual try-ons, stylistic transformations, and multi-image compositing. Text rendering accuracy is notably improved compared to its predecessor, and generation speed is up to 4x faster. It is accessible to all ChatGPT users as well as developers building applications in e-commerce, marketing, and creative tooling.
What GPT Image 1.5 supports
Text-to-Image Generation
Generates images from text prompts at resolutions up to 1536×1024 and 1024×1536 pixels. Supports a 4000-token context window for detailed prompt input.
Precise Image Editing
Adds, removes, blends, or transposes elements in existing photos while preserving lighting and composition. Follows nuanced instructions to change only the specified parts of an image.
Face & Character Preservation
Maintains consistent facial likeness across inputs, outputs, and sequential edits. Useful for portrait retouching, virtual try-ons, and character consistency across a chain of edits.
Inpainting
Modifies specific regions of an image without affecting surrounding areas. Allows targeted edits such as replacing backgrounds or altering individual objects.
Improved Text Rendering
Generates images containing readable text with higher accuracy than the predecessor model. Suitable for creating mockups, signage, and branded visuals.
Multi-Image Compositing
Blends subjects from multiple source images into a single coherent scene. Accepts image URL arrays as input to support multi-source compositing workflows.
Fast Generation Speed
Produces images up to 4x faster than its predecessor model. Speed improvements apply to both generation and editing tasks.
API Access
Available via the OpenAI API using the model ID gpt-image-1.5. Suitable for developers integrating image generation into e-commerce, marketing, and creative applications.
