Best for
High-quality image generation and precise multi-turn image editing through the OpenAI API or ChatGPT.
Overview
OpenAI's newest image models, released in the API as two tiers: Flare (fast, default for everyday work) and Sunburst (slower, for edits where precision matters most). They share GPT Image 2 token pricing and also power ChatGPT Images 2.5. As of October 2026 they lead the Artificial Analysis text-to-image arena.
Strengths and limits
- Top two entries on the Artificial Analysis text-to-image leaderboard (Oct 2026)
- Flare tier: up to 50% lower latency than GPT Image 2 (OpenAI claim)
- Custom sizes up to 3840 px per edge; transparent PNG/WebP backgrounds
- Sunburst is noticeably slower than Flare
- Resolutions above 2560x1440 are experimental; precise text placement and layout can still fail
