What is GPT Image 1.5?
GPT Image 1.5 is an image generation and editing model from OpenAI. It launched on December 16, 2025, alongside the redesigned ChatGPT Images, and OpenAI described it as a shift from novelty image generation to practical, everyday visual work. It was OpenAI's flagship image model until GPT Image 2 arrived in 2026.
Compared with GPT Image 1, OpenAI says it follows instructions more closely, edits more precisely, and generates images up to four times faster in ChatGPT. The biggest improvement is in editing: when you change one thing, it does a better job of keeping everything else—lighting, composition, a person's face, and brand logos—the way it was. That makes it well suited to clothing and hairstyle try-ons, background swaps, and product catalogs built from a single photo. It also renders dense and small text better than its predecessor.
On PixPal, GPT Image 1.5 is the most affordable OpenAI model in the studio. You can write a prompt to create a new image, or upload up to 16 reference images to edit or combine them. Choose a square, portrait, or landscape size up to 1536 pixels on the long side, then pick Low, Medium, or High quality.
