It's our new text-to-image model: a 9.3B single-stream diffusion transformer trained entirely from scratch.

We focused heavily on controllability through structured JSON prompts, with strong text rendering, spatial awareness through bounding box guidance, and color palette control.

It has the best text rendering of any open-weight model we've tested so far, and the NF4 quantized checkpoint runs on a single 24GB GPU.

For more technical details and examples see our blog post: https://ideogram.ai/blog/ideogram-4.0/

We will be happy to answer any questions :)

The galery of generated images looks amazing, it's hard (but often possible) to spot inconsistencies in detailed images.

Non-commercial license, you should not call that "open-weight". Words have meaning.

And people are having a laugh at how censored the model is.

The model should perform better with JSON prompts than with natural language prompts. The safety filter may also be triggered incorrectly by natural language prompts, we are aware of this and will make a future checkpoint update to improve it.

See how to prompt the model here: https://github.com/ideogram-oss/ideogram4/blob/main/docs/pro...
