01 · Overview
What is GPT Image 2.5 Sunburst?
Sunburst is the detailed half of OpenAI's 2.5 pair: where Flare answers fast and literal, Sunburst spends more time on atmosphere — richer light, deeper texture, the kind of detail that rewards a second look.
Three tiers: 1K at 2 credits, 2K at 5, 4K at 7. Edits cost the same as generations at every tier and take up to sixteen references — the most of any model on Pizyn. New accounts start with 20 free credits: ten 1K images.

GPT Image 2.5 Sunburst FAQ
How much does GPT Image 2.5 Sunburst cost?
2 credits ($0.02) at 1K, 5 credits ($0.05) at 2K and 7 credits ($0.07) at 4K — for generation and edits alike. Reference images are never charged.
Sunburst or Flare?
Same prices, different character: Sunburst is the detailed, atmospheric tier; Flare is the fast, literal one. Run the same prompt on both and keep the one you like.
How many reference images can an edit use?
Up to sixteen in the studio — the most of any model on Pizyn — all included in the same price as a fresh generation.
How is 2.5 different from 2.6?
2.6 is the newer flagship with GIF, SVG and markup editing; 2.5 is the previous generation at a lower price (from 2 credits vs 5). For most still images, 2.5 is the value pick.
How long does a generation take?
Typically under a minute at 1K; the larger tiers can take a little longer.
When should I use a different model?
For GIF/SVG/markup features (GPT Image 2.6), the lowest flat price (Muse Image at 1 credit), or four variations in one run (Midjourney).
