Ideogram 4.0 – open-weight 9.3B text-to-image model

Ideogram 4.0 is a 9.3B parameter open-weight text-to-image model built from scratch, designed for developers and AI researchers who need precise control over image generation. It introduces structured JSON prompts for enhanced controllability, including accurate text rendering, spatial awareness via bounding box guidance, and color palette conditioning. This model is interesting because it combines state-of-the-art diffusion transformer architecture with unprecedented structured prompt fidelity, enabling complex, multi-element compositions that were previously difficult to achieve.
