GPT Image 2.5 Flare vs GPT Image 2.5 Sunburst

Compare pricing, context limits, supported inputs and deployment options to choose a model for your workflow.

Flare and Sunburst share an image-generation family but are positioned for different points in a design workflow. Flare emphasises faster iteration; Sunburst emphasises precise creation and edits. Both accept text and image inputs through OpenAI’s documented image-generation interfaces. They should be compared as image services, with the same brief and reference assets.

Start with three tasks: a fresh composition, an edit that must preserve a supplied product and a layout containing required text. Hold image size and quality constant for the first comparison, then explore whether a different setting changes the decision. Inspect full-resolution outputs for wording, object count and unintended changes. Keep unsuccessful drafts in the time and cost measurement.

Text input, image input and generated image tokens have separate rates. The amount billed depends on the actual request and output settings, so an ordinary text-model output price is not a useful estimate for a finished visual.

Workload guidance

Which model should you choose?

Start with Flare for draft alternatives and frequent revisions when its outputs satisfy the brief. Evaluate Sunburst when preserving details or completing a final edit matters enough to justify a more precision-focused route. Choose from the proportion of accepted deliverables, time to an accepted result and actual usage. Neither positioning statement establishes that every prompt will be better on one variant; use the references and layouts your team needs.
