GPT Image 2.5

What It Does

GPT Image 2.5 is OpenAI's image-generation and image-editing model family, consisting of two specialized models: Flare for fast everyday generation and Sunburst for detailed generation and precision-focused editing. Released on September 8, 2026, GPT Image 2.5 creates and edits images from both text and image inputs, enabling workflows from quick creative drafts to complex production-ready assets.

Who It's For & Main Problem It Solves

GPT Image 2.5 serves designers, marketers, content creators, and product teams who need to generate original visuals or edit existing images without traditional design tools. It solves the challenge of producing high-quality images at scale—whether for social media, marketing campaigns, product mockups, or creative exploration—by translating natural language prompts and reference images into production-ready outputs.

Key Features & Capabilities

• Dual-model architecture: Choose Flare for speed and high-volume generation, or Sunburst when detail and edit control matter more
• Text-to-image generation: Describe subjects, settings, composition, lighting, and visual treatment in natural language
• Image editing with preservation: Upload existing images and request focused changes while preserving identity, geometry, layout, camera angles, and backgrounds
• Reference-based workflows: Guide results with multiple reference images assigned roles (person, product, outfit, style, composition, or background)
• Text rendering in images: Generate readable text within images by quoting exact wording and specifying location
• Transparent asset creation: Export PNG images with transparent backgrounds and clean alpha edges
• Multi-round refinement: Iteratively refine outputs with follow-up instructions while tracking identity, objects, and layout consistency
• Quality tiers: Select from Auto, Low, Medium, High, XHigh, and Max quality settings
• Background control: Choose auto, opaque, or transparent backgrounds

Typical Workflows & Use Cases

Flare excels at fast drafts, everyday marketing and social visuals, prompt testing, rapid variations, and higher-volume generation workflows. Sunburst targets detailed and demanding image edits, subject and product preservation, reference-based creative work, and complex compositions for final production assets. Practical workflows include creating images from prompts, editing existing visuals, guiding results with references, adding text to images, creating transparent assets, and refining outputs through multiple rounds.

Integrations

GPT Image 2.5 is accessible through OpenAI's official Image API and Responses API for token-based usage. The independent gptimage2-5.io service also provides browser-based access using separate site credits, allowing users to compare both models, review matched benchmarks, and generate images without API integration.

What Differentiates It

The choice between Flare and Sunburst gives users explicit control over the speed-quality tradeoff. Independent third-party testing provides matched benchmarks with identical prompts, settings, and quality tiers, measuring latency, cost, text accuracy, subject consistency, and edit drift across both models—transparency that helps teams select the right model for each workflow and validate outputs before production use.
