What makes ChatGPT-Image-2.5 Sunburst different
ChatGPT-Image-2.5 Sunburst generates and edits, so it is not only about the first render — it is about getting to the exact image you need.
Built for precision
Sunburst is OpenAI's base model in the ChatGPT Image 2.5 family, optimized for quality, with higher image quality than ChatGPT-Image-2.0.
Edits that hold up over multiple turns
Sunburst is tuned for workflows where a reference subject, product, or character has to survive several rounds of edits without drifting.
Near-perfect text rendering
Sunburst renders readable text in posters, labels, and UI mockups, carrying forward the text accuracy improvements from the ChatGPT Image 2.5 family.
Higher precision, longer render time
Sunburst trades some speed for tighter control across edits, so results need less rework before they are production-ready.
