GPT Image 2.5 Flare is the speed-oriented API variant within OpenAI's GPT Image 2.5 image-generation update released in September 2026. The broader update was framed around faster iteration, sharper detail, stronger reference-image fidelity, and more precise editing, with the consumer product marketed as ChatGPT Images 2.5 and developers receiving two API models: Flare for speed and Sunburst for tighter control over intricate detail. Both variants generate images from text prompts and can edit existing images, with fal's listing describing capability at output resolutions up to 3840px.
Flare is positioned as the default choice for most image work, claimed to deliver higher quality than GPT Image 2 at roughly half the latency, making it well suited to workflows that need quick turnaround on revisions. The model is intended to make the full revision loop more dependable, preserving a person or product across edits while changing only the requested element and carrying earlier decisions through multiple passes. Practically, this makes Flare a fit for creators, marketers, and product teams working on infographics, logos, comics, diagrams, and other assets where consistent identity and iterative refinement matter more than maximum detail fidelity, which is the territory of its Sunburst sibling.
