GPT Image 2.5 Flare Image to Image example

Example — generated from this input

Change the recipe card title to "BLUEBERRY OAT PANCAKES" and replace the halved lemon with a small bowl of rolled oats. Keep the handwriting style, the three ingredient lines, the pancakes, the blueberries, the syrup jug, the lighting and the camera angle exactly the same.

Pricing

Cache read /M: $2.00

About $0.043 per image at default settings (high quality, 1 image); higher quality, larger sizes and more images use more tokens.

Each request temporarily reserves $0.0427; you are charged for actual usage, usually within a minute: any unused amount is released and any usage above it is charged to your balance, even if that takes it below zero; while your balance is below zero, new requests are paused until a top-up covers it.

Failed generations are not charged.
