Why use GPT Image 2.5 Sunburst for image?
High-quality image generation
GPT Image 2.5 Sunburst delivers production-ready outputs with clean structure, sharp detail, and strong prompt adherence. Ideal for character art, environments, and marketing assets.
Strong prompt control
The model interprets creative instructions with high accuracy, even when switching between different styles, lighting setups, or character directions.
Clean compositions for UA
Maintains stable framing, clear silhouettes, and high focal clarity. Assets read well at mobile sizes, making it strong for UA experiments and ad creatives.
Rapid character and cosmetic ideation with strong structure
Quickly explore character poses, cosmetic ideas, and early art directions. Clean silhouettes and expressive results help teams evaluate concepts before moving to heavier models.
Fast UA creative exploration and thumbnail testing
Generate clear, high-readability frames that work well for quick A/B testing across networks. Test multiple creative angles and iterate quickly based on results.
Lightweight environment and item exploration for LiveOps
Draft environments, themed content, shop items, and event visuals in a rapid loop. Ideal for early-stage direction setting before committing to final polish.
FAQ
How much does GPT Image 2.5 Sunburst cost? Is it free?+
How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
