Quick take
OpenAI's quality-first GPT Image 2.5 model for demanding generation, precise edits, subject preservation, typography, and high-resolution creative work.
Sunburst is the quality-first option, not automatically the best value for every image. Test Flare after quality passes, inspect exact text and preserved details, and measure cost per accepted output.
A design-oriented image model with open weights, multilingual typography, structured layout control, editable elements, and simple per-image API tiers.
Generation, edit, hosted, and self-hosted routes can have different features and licensing obligations; validate the exact path you plan to use.

Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
OpenAI says direct API inputs and outputs are not used for model training by default. Standard abuse-monitoring retention and organization-specific data controls still apply.
Provider and API links
The model page does not publish a complete retention or training-use commitment for every access route. Review Ideogram's current API agreement or your self-hosting controls.
