What makes GPT Image 2.5 unique
Two variants in one model: Flare is OpenAI's fastest model for high-quality everyday generation; Sunburst is its most capable for image editing where precision matters most.
Sharper detail and markedly better text rendering than GPT Image 2 — typography, posters, and layouts come out clean.
Roughly 50% lower latency than GPT Image 2 on the Flare variant — everyday images in about 10–20 seconds.
Accepts up to 16 reference images for image-to-image workflows and character-consistent generation.
Medium and high quality tiers so you only pay for the fidelity a job needs.
Supports prompts up to 20,000 characters for detailed creative briefs, style notes, and composition requirements.

How GPT Image 2.5 works
GPT Image 2.5 takes a text prompt and, optionally, up to 16 reference images. Choose the variant — Flare for speed, Sunburst for editing precision — plus a quality tier and aspect ratio, then submit. The model generates the image and returns it in seconds; with references it runs in edit mode, following the supplied subjects and style while applying your prompt.
