GPT Image 2.5 Sunburst

GPT Image 2.5 Sunburst sits inside OpenAI's broader GPT Image 2.5 image generation release, documented on the OpenAI developer documentation site at a dedicated model page. Within that release, Sunburst is positioned as the precision-focused sibling to GPT Image 2.5 Flare, which is framed for high-speed production workflows. This split suggests an intent to give teams a choice between throughput-oriented generation and a more deliberate variant tuned for careful visual work, while sharing the same underlying family identity and tooling story.

In practice, Sunburst is described as part of a launch that bundles image creation with a Sketch drawing tool, comment-based multi-turn image editing, and support for output up to 4K resolution, features that lend themselves to iterative design, mockup refinement, and high-fidelity creative production. Because it is paired with a Flare counterpart in the same release, teams can plausibly mix the two depending on whether a task favors speed or refinement. The model's role is best understood as a specialized image generator within OpenAI's ecosystem rather than a general-purpose multimodal system, making it a reasonable fit for creative pipelines that need high-resolution image output and round-trip editing.

Coverage

A press release dated September 11-12, 2026 describes GPT Image 2.5 as OpenAI's latest image generation platform, splitting image creation into two purpose-built models: Flare for speed-first workflows and Sunburst for precision-first creative production. Sunburst is positioned for maximum editing control and productio The release frames Sunburst as the variant of choice for precision editing rather than throughput, complementing Flare's speed-first design. It lists Sunburst alongside a Sketch drawing tool and multi-turn comment-based editing as part of the GPT Image 2.5 launch bundle. The source is a syndicated press-release wire it

Official sourceDocumentation

OpenAI's official image prompting guide documents GPT Image 2.5 as a two-variant family. "GPT Image 2.5 Flare" is described as the small, speed-optimized model with image quality comparable to GPT Image 2, while "GPT Image 2.5 Sunburst" is positioned as the base, quality-optimized model offering higher image quality th For migration guidance, the guide recommends starting a new workflow with GPT Image 2.5 Flare when speed is the priority or GPT Image 2.5 Sunburst when demanding quality is the priority, then inspecting output and looking for opportunities to reduce latency.

On September 8, 2026, OpenAI announced ChatGPT Images 2.5 alongside two new Images API model IDs: gpt-image-2.5-flare and gpt-image-2.5-sunburst, replacing the single-model approach of the prior generation. According to a third-party guide based on hands-on API testing (41 generations), bare model IDs like "gpt-image-2 OpenAI's own positioning frames GPT Image 2.5 Sunburst as the precision-first variant (versus Flare for high-throughput workflows), with consumer-side features including Sketch (compositional drawing reference), Templates, comment-scoped image edits, and prompt sharing rolling out across ChatGPT, ChatGPT Work, and Code
