| Catalogue id | gpt-image-2.5-sunburst |
The Catalogue id row is present because the model's API page path names it | |
exactly (developers.openai.com/api/docs/models/gpt-image-2.5-sunburst), and the | |
| slug on this wiki cannot reach a dotted id. It is **copied from the location, not | |
| guessed** (source). |
Pricing is identical to GPT-Image-2.5 Flare — the same two passes
carry both, and OpenAI's pricing page is reported as listing the two models at
the same rates. Context window is unknown: no resolution or token-accounting
figure was published, so nothing here converts to a per-image cost.
Release Date
2026-09-08, alongside ChatGPT Images 2.5 and GPT-Image-2.5 Flare. Captured 2026-09-09, +1 day (source).
Benchmarks
None published, for this model or its sibling. Its stated advantage — "an extra level of precision for detailed creative work" — is not attached to any measurement, and its stated cost, longer generation times, is not quantified either (source).
Use Cases
Premium visual workflows that benefit from tighter control across edits — production-ready campaign creative and polished product imagery are the two named (source).
Compared To
- GPT-Image-2.5 Flare — the comparison this page exists for, and it cannot currently be made. Same vendor, same day, same published per-token rates; the difference is stated as precision against generation time, and neither side of that trade has a number. A developer choosing between them from what has been published is choosing on adjectives
- ChatGPT Images 2.5 — the ChatGPT-side model
- GPT Image 2 — the predecessor both API models are priced against; no page on this wiki
