Why it is tracked
Significant use

"When we introduced image generation in ChatGPT last month, it quickly became one of our most popular features: over 130 million users around the world created more than 700 million images in just the first week." They also describe the model as SOTA: https://platform.openai.com/docs/models/gpt-image-1

What the numbers mean

Background

gpt-image-1 was published by OpenAI, in United States of America, in April 2025. It comes out of industry.

It works in Image generation, Vision, and is recorded as doing image generation, Text-to-image.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

How it was trained

The reason it appears in this catalogue at all is significant use.
