Facts checked September 9, 2026
Set your usage. Your estimate updates as you type.
Example output: square 1,024 × 1,024 images. Prices depend on supported resolution and quality; edits and retries can cost extra.
Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

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.
Black Forest Labs' production-focused image model for scalable generation and editing, precise composition, and multi-reference creative workflows.
The preview endpoint can change. Use the fixed endpoint when repeatability matters, and verify data terms for whichever host receives your reference images.

How to choose
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 specification does not itself establish data-processing terms. Review the contract and region of the API route you select before sending confidential reference images.
