Ideogram 4.5 (High)

Ideogram 4.5 (High) is an advanced image generation and precision editing model developed by Ideogram, released on September 30, 2026. Built specifically to mitigate image drift during multi-turn workflows, the model is engineered to preserve untouched pixels, colors, and textures across repeated editing passes. This design allows users to chain sequential modifications—such as color adjustments, relighting, and text edits—without accumulating the pixel shifts or degradation commonly found in iterative image generation models.

The model introduces dedicated capabilities for high-resolution processing, supporting native outputs up to 2K presets and handling large-format assets (such as 24.2 MP images at 4,016 by 6,016 pixels) without mandatory prior downscaling. Through its high precision edit configurations, users can supply a source image, up to four reference images, and optional masks to restrict changes to specific zones. This structural constraint makes it well-suited for professional applications like product photography variation, step-by-step photo restoration, and exact text modification or translation directly inside layouts.
