GPT Image 1 API Complete Guide
Learn how to integrate the GPT Image 1 API, explore text-to-image and image-to-image capabilities, and start generating professional images.
What is the GPT Image 1 API?
The GPT Image 1 API is built on OpenAI's multimodal image model. It accepts text and optional image inputs to generate high-quality visuals — with natural language understanding for complex prompts and optional prompt enhancement for specialized scenarios like 3D renders.
The GPT Image 1 API supports two modes: text-to-image for creating visuals from scratch, and image-to-image for editing existing photos. You can supply up to 5 reference images and request up to 4 variants per call.
With aspect ratios 1:1, 2:3, and 3:2, pricing at $0.035 per image, and generation times of 40-70 seconds, the GPT Image 1 API delivers production-ready image workflows through a single REST endpoint.
