Why GPT Image 2.5 Is Built for Production Workflows
One model page, two engines: flip between Fast and Ultra, watch the credit cost update live, and keep full control over ratio, resolution, and references.
Two Engines: Fast and Ultra
The Fast engine (GPT Image 2.5 Flare) is tuned for lower latency and higher-volume generation. The Ultra engine (GPT Image 2.5 Sunburst) is built for premium creative work that needs tighter control and more polished output. Switch anytime — the price updates before you run.
Stronger Reference Fidelity
Upload up to 8 reference images and GPT Image 2.5 preserves faces, products, and recognizable subjects more consistently across edits, while introducing new environments, styles, and compositions.
12 Aspect Ratios + 4K Output
From 1:1 and 16:9 to cinematic 21:9, 27:16, and 16:27 — pick the exact ratio for your placement, then scale from 1K up to 4K resolution for print-ready assets.
Precise, Targeted Editing
GPT Image 2.5 follows focused edit instructions more reliably across complex scenes: change lighting, swap backgrounds, or restyle a product while everything else stays untouched.
Predictable, Transparent Pricing
Fast costs 3 credits at 1K, 4 at 2K, and 7 at 4K. Ultra costs 4, 6, and 9. The Generate button always shows the exact cost before you run — no batch-size surprises.
Durable Delivery
Sketchto stores every result in R2 and serves it from a stable asset URL, so downloads keep working long after the provider link expires.
Real-World Applications of GPT Image 2.5
Discover how designers, marketers, and product teams use GPT Image 2.5's dual engines and precise editing to ship faster and iterate smarter.

Brand & Campaign Assets
Creative teams draft with the Fast engine, then re-run the winning prompt on Ultra for polished campaign visuals — consistent brand elements, print-ready 4K, and exact placement ratios.

E-commerce & Product Imagery
Upload product references and generate lifestyle mockups, catalog shots, and market-specific variants that keep shape, color, and styling close to the source across every edit.

Social & Content Production
High-volume creators use the Fast engine for daily posts — 12 aspect ratios cover every placement, and Match input keeps reference-based edits in the original format.

Pro Tips for Mastering GPT Image 2.5
Match the engine to the job:
Use Fast for exploration, drafts, and high-volume social content. Switch to Ultra for final campaign assets, brand visuals, and polished product imagery where refinement matters.
Use references for identity:
When a product, person, or brand object must stay recognizable, upload reference images and state exactly which traits should remain unchanged — GPT Image 2.5 keeps subjects consistent across repeated edits.
Compose for the placement:
Pick the aspect ratio that matches your target medium before generating — 16:9 for banners, 9:16 for stories, 21:9 for cinematic headers — then upscale to 4K only for the final winner.
