GPT Image 2.5 Sunburst (max)

GPT Image 2.5 Sunburst (max) is an image generation model published by OpenAI. It sits in the GPT Image family, OpenAI's line of models that render images from text prompts rather than returning text completions. The "Sunburst" designation identifies this specific 2.5-series variant, and the "(max)" suffix indicates the higher-effort tier of that variant — in OpenAI's image APIs, tiered variants of the same model generally trade additional generation time and compute for more rendering detail, with lower tiers of the same model reserved for faster, cheaper output. Because this is an image model, the characteristics that matter are different from those of a chat LLM: output resolution and aspect ratio options, prompt adherence (how faithfully the generated image reflects a detailed instruction), text rendering inside images, and end-to-end generation latency. Context window and token throughput are not meaningful measures here. We do not track a confirmed public specification sheet for this entry beyond its creator and model type, so prospective users should confirm supported sizes, input modes (text-to-image versus image editing), and content policy behavior against OpenAI's own API documentation before building against it. In practice, models in this category are used for marketing and social creative, product and concept mockups, storyboard frames, illustration drafts, and synthetic imagery for design exploration. The max tier of a given image model is typically chosen for final or near-final assets where visual quality matters more than per-image latency, while faster tiers of the same model are used for iteration and bulk drafts. Providers listed on this page may expose the model with different throughput, queueing, and availability characteristics, so comparing on the pricing table alongside latency expectations is worthwhile.
