Ideogram says its new model Ideogram 4.5 solves one of AI image editing's biggest headaches. When you edit part of an image, the rest shouldn't change. Swap someone's outfit, and their body shape and background should stay intact. Leading models like GPT-Image 2.5 and Nano Banana have gotten much better at this, but they still tend to produce artifacts, especially after multiple edits. Ideogram 4.5 only touches what the user tells it to, the company claims. Target use cases include product photography, interior design, photo restoration, and in-image text editing. Early testers confirm strong consistency across edits.
Ideogram 4.5 offers four quality tiers ranging from 0.8 to 22 cents per image, all at native 2K resolution. The model is available now on the Ideogram platform and through the API. Partners include Picsart, Runway, Pika, and Leonardo AI. Ideogram also says an open-weight release is coming soon.
