Ideogram 4.0 is Ideogram's first open weights release and debuts at #8 on our Open Weights Text to Image Leaderboard
Ideogram 4.0 is the latest release from @ideogram_ai. Alongside their first party API, Ideogram is releasing 4.0 with open weights and a commercial license.
The model generates 2K x 2K outputs (~4MP), with strong text rendering across languages, bounding box layout control, and transparent backgrounds. Ideogram 4.0 uses structured JSON prompts that specify composition and individual scene elements, with a prompt enhancer that expands natural language prompts into this structured format. Note that the prompt enhancer is only available via the Ideogram proprietary API, though it is free to use.
