4o image generation is a new, significantly more capable image generation approach than our earlier DALL·E 3 series of models. It can create photorealistic output. It can take images as inputs and transform them. It can follow detailed instructions, including reliably incorporating text into images. And because it is embedded natively, deep in the architecture of our omnimodal GPT‑4o model, 4o image generation can use everything it knows to apply these capabilities in subtle and expressive ways, creating images that are not only beautiful, but also useful.
