Ideogram 4 GGUF
Ideogram 4 is a diffusion transformer built for text rendering and graphic design. It ships two diffusion components: the main transformer and an unconditional transformer used by CFG workflows. This repository publishes GGUF quants of both.

Available Quantizations
Each quant level is published for both the main transformer and the unconditional transformer.
| Quant | Size per file | Main file | Unconditional file |
|---|---|---|---|
| Q4_0 | 5.26 GB | ideogram4-transformer-q4_0.gguf | ideogram4-unconditional_transformer-q4_0.gguf |
| Q4_1 | 5.78 GB | ideogram4-transformer-q4_1.gguf | ideogram4-unconditional_transformer-q4_1.gguf |
| Q5_0 | 6.30 GB | ideogram4-transformer-q5_0.gguf | ideogram4-unconditional_transformer-q5_0.gguf |
| Q5_1 | 6.83 GB | ideogram4-transformer-q5_1.gguf | ideogram4-unconditional_transformer-q5_1.gguf |
| Q8_0 | 9.44 GB | ideogram4-transformer-q8_0.gguf | ideogram4-unconditional_transformer-q8_0.gguf |
The main and unconditional transformers do not need to use the same quant level. Higher quants keep text legibility sharper.

Suggested pairings
| Main transformer | Unconditional transformer | Notes |
|---|---|---|
| q8_0 | q8_0 | Highest precision pair |
| q8_0 | q5_1 | High precision main, less memory on the unconditional side |
| q5_1 | q4_1 | Balanced quality and size |
| q4_0 | q4_0 | Smallest pair |
ComfyUI Setup
Load the model with the GGUF loader node from comfyui-gguf-reboot. The loader node gives the best performance. Use the Unet Loader (GGUF) or Unet Loader (GGUF/Advanced) node in a workflow that accepts separate main and unconditional models.
Dependencies
Place these files in the ComfyUI model folders before running a workflow. You also need the text encoder and VAE from the upstream Ideogram 4 release.
| Component | Folder |
|---|---|
| Main transformer | models/diffusion_models/ or models/unet/ |
| Unconditional transformer | models/diffusion_models/ or models/unet/ |
| Text encoder | models/clip/ or text_encoders/ |
| VAE | models/vae/ |
Ideogram 4 has no workflow files in this repository. Use the ComfyUI template from the upstream Ideogram 4 release and swap in the GGUF loader node.
