Show HN: Ideogram 4.0 – open-weight 9.3B text-to-image model
Ideogram 4: Open image model at the forefront of design - ideogram-oss/ideogram4
Summary not yet generated for this article.
Original Text
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 :)
