Ideogram ships 4.5, a model built for editing

Ideogram released Ideogram 4.5, a model aimed at the second half of image work rather than the first. The problem it targets is drift: every edit introduces pixel shifts, color changes and texture artifacts, and by the tenth pass the image has visibly degraded. Ideogram’s claim is that 4.5 changes only what you ask it to change and leaves the rest alone.

It generates from text at 1K and 2K presets, and edits a source image using up to four reference images, with an optional mask that limits where changes land. The model page compares it directly against GPT Image 2.5 Sunburst, Nano Banana Pro and Nano Banana 2, arguing that those outputs become unusable within a few edits while 4.5 stays clean. It also edits high resolution crops without downscaling first, so an edited region can be stitched back into a 4,016 by 6,016 pixel original intact.

Pricing runs across four quality tiers from 0.8 cents to 22 cents per image, all at native 2K, available on the Ideogram platform and through the API where it is exposed as ideogram-4-5. One thing worth knowing: Ideogram has published no dated announcement for this release. Its newsroom and blog return errors to automated fetches and its model page carries no date, so the September timing comes from the API documentation and from integrators like Runway and Recraft rather than from Ideogram itself.
