OpenAI GPT Image 2.5 Sunburst
OpenAI's most capable image model, built for workflows where editing precision matters most, with strong subject preservation, localized changes and sharp text rendering across iterative edits.
OpenAI's GPT Image 2.5 Sunburst is a cloud image-generation model. It generates images from a text prompt, and can take reference images to guide style or composition (image-to-image). It outputs up to 4K across 8 aspect ratios and can return up to 10 images per request. Images can be saved as PNG, JPEG, and WebP. It runs through Runware, OpenRouter, Replicate, and OpenAI using your own API key, from $5.00 per million input tokens.

Samples
Generated with GPT Image 2.5 Sunburst via Replicate. The same three prompts run against every model in the catalog, first result kept, so the only thing that changes between two models’ tiles is the model.
Materials, reflections, macro detail
Skin texture, lighting, shallow depth of field
Text rendering, layout, flat colour
