Introduction

GPT-Image-2 uses POST /v1/images/generations for both text-to-image and image-to-image: omit image for T2I; include image (URL or Base64) for I2I. Responses use b64_json with usage token stats. For full parameters and other image models, see Image generation.

Authentication

string

required

Bearer Token, e.g. Bearer sk-xxxxxxxxxx
