Verdict
When to choose each
GPT Image 2.5 Sunburst
Where it leads
- Higher Arena Text-to-Image score, 1427 Elo vs 1409 Elo
- Higher Arena Image Edit score, 1517 Elo vs 1476 Elo
Best for
- Hero imagery, detailed edits and text-heavy graphics where quality matters most
Watch out for
- OpenAI publishes no per-image price, and its GPT Image 2 calculator does not estimate 2.5 token use, so cost per image has to be measured
- OpenAI followed it with GPT Image 2.6 Sunburst on November 4, 2026, which is faster at the same token rates, although Arena still rates 2.5 Sunburst higher
GPT Image 2.6 Sunburst
Where it leads
No measured lead over GPT Image 2.5 Sunburst in this data.
Best for
- Detailed compositions, brand-consistent edits and animated GIFs where quality matters most
Watch out for
- Arena's first ratings put it below GPT Image 2.5 Sunburst: 1409 against 1427 for generation and 1476 against 1517 for editing, on fewer than 4,000 votes so far
- OpenAI's pricing page lists no batch rate for 2.6 yet, while GPT Image 2.5 costs half in batch
