  "description": "Ideogram 4.0 open-weight text-to-image model (9.3B single-stream DiT) run locally in ComfyUI. Best-in-class in-image text rendering and typography. Uses a Qwen3-VL-8B text encoder and the Flux 2 VAE, plus a second 'unconditional' transformer that drives dual-branch CFG (there is no user negative prompt). Authored in natural language. Weights are non-commercial; generated images may be used commercially.",

  "notes": "REQUIRES a ComfyUI version with native Ideogram 4 support (the UNETLoader 'ideogram4' arch, CLIPLoader 'ideogram4' type, Ideogram4Scheduler, DualModelGuider, CFGOverride). Weights from the UN-GATED Comfy-Org/Ideogram-4 mirror (no HF token needed). Two transformers load via two UNETLoaders; the unconditional one feeds DualModelGuider.model_negative. Recommended: Default = 20 steps, Turbo = 12, Quality = 48; DualModelGuider guidance 7; CFGOverride [3, 0.7, 1]; scheduler mu 0.5 / std 1.75; sampler euler. Native output up to 2048px. On a 32 GB card (RTX 5090) full fp8 fits with text-encoder offload; drop the unconditional transformer or encoder to nvfp4 if VRAM is tight. NON-COMMERCIAL weights: fine for personal/local use; commercial deployment of the model needs Ideogram's paid license (generated images themselves are fine to use commercially, except training competing models).",
