GPT Image 2.5 Sunburst
⧉GPT Image 2.5 Sunburst is the other style branch of the next-generation OpenAI image model. Against Flare it comes back with heavier grain and brushwork and firmer highlights, carrying more visual information - a fit when you want material and physical presence. Capabilities and price are identical to Flare. Text-to-image and image-to-image, 1K / 2K / 4K, with a C2PA content credential in every render. Set model to gpt-image-2.5-sunburst. Billed per image, failed jobs refunded in full.

imageAbout GPT Image 2.5 Sunburst
GPT Image 2.5 Sunburst is one of two style branches of the next-generation OpenAI image model; its output is grainier, with heavier brushwork and firmer highlights. NezhaGate serves it through the OpenAI-compatible images API: /v1/images/generations for text-to-image and /v1/images/edits for image-to-image, at 1K / 2K / 4K and multiple aspect ratios, with a C2PA content credential embedded in every render. Set model to gpt-image-2.5-sunburst. Billed per image, failed jobs refunded in full, at exactly the same price as GPT Image 2.
Use cases
Article covers, event posters and product shots, with accurate typography; 1K is already enough for web and social.
Put an existing image in the image parameter or use /images/edits to repaint a region, swap the background or shift the style.
Async jobs plus stable direct links make scripted bulk production easy, and failures cost nothing.
Every render carries a C2PA signature, so you can state that the asset is AI-generated and keep an audit trail.
How to choose
Flare and Sunburst cost the same and do the same things; only the look differs. Pick Flare for clean layouts and legible type, Sunburst for grain and material feel. If you just need ordinary output, the existing gpt-image-2 is priced the same and remains a fine choice.
