What it is good at

Two tiers: Flare is OpenAI's fastest model for high-quality everyday images; Sunburst is for work where editing precision matters most.
Edits that change only what you ask, with a mask option, and reference people who stay recognizable through several edits.
Transparent backgrounds and complex layouts with natural light and rich texture.

Honest limits

Sunburst takes longer to generate than Flare in exchange for more detail.
Higher quality settings (up to xhigh and max) add detail but also time.
Custom sizes must have sides in multiples of 16, no side over 3840 px and a ratio of 3:1 or less.
