If you have city96 version installed, remove it first (same folder name causes conflicts).Installation steps:1. Stop ComfyUI2. Delete the entire <code>ComfyUI-GGUF</code> folder in custom_nodes (not just the files inside it)3. Clone: <code>git clone https://github.com/molbal/ComfyUI-GGUF.git</code>4. Restart ComfyUI💡 Optional: If you encounter any import errors, install requirements:<pre><code>pip install -r ComfyUI-GGUF/requirements.txt</code></pre>✅ That's it! This single extension handles both UNET and CLIP loading.---📊 Choosing the Right QuantizationThe HuggingFace repository includes helpful charts for:- Inference Speed: How fast each quant generates images- Memory Usage: How much VRAM each quant requiresGeneral Guidelines:- Q4_0: Lowest VRAM (~5.5 GB), fastest, good quality- Q5_0/Q5_1: Balanced VRAM (~6.8-7.3 GB), better quality- Q8_0: Highest VRAM (~10 GB), best quality, slower💡 Check the charts in the repository for detailed comparisons!---🗒️ JSON Prompting (Optional)Ideogram 4 works best with structured JSON prompts. This workflow uses Gemma 4 to automatically convert your natural language prompts into JSON format for:- ✅ Better text rendering and typography- ✅ More accurate composition control- ✅ Consistent results across generationsJust write a simple prompt like "A poster for a coffee shop" and let Gemma 4 handle the rest!---💡 Quick Tips- For TurboTime LoRA (v2.0): Use only <code>ideogram4-transformer-q4_0.gguf</code> (no unconditional model needed) - TurboTime LoRA: Download from: <a target="_blank" rel="ugc" href="https://huggingface.co/ostris/ideogram_4_turbotime_lora">https://huggingface.co/ostris/ideogram_4_turbotime_lora</a>- For standard mode (v1.0): Use both main and unconditional models- CFG Settings: 0.0 for TurboTime, 7.0 for standard mode- Scheduler: mu=0.5, std=1.75 for TurboTime | mu=0.0, std=1.5 for standard- Quantization: Q4_0 for lowest VRAM, Q8_0 for best quality🙏 Credits- Ideogram 4 Model: [Ideogram AI] <a target="_blank" rel="ugc" href="https://ideogram.ai/">https://ideogram.ai/</a>- GGUF Conversion &amp; Custom Node: [molbal] <a target="_blank" rel="ugc" href="https://github.com/molbal/ComfyUI-GGUF">https://github.com/molbal/ComfyUI-GGUF</a>- TurboTime LoRA: [ostris] <a target="_blank" rel="ugc" href="https://huggingface.co/ostris/ideogram_4_turbotime_lora">https://huggingface.co/ostris/ideogram_4_turbotime_lora</a>- Workflow: [dvdufo] <a target="_blank" rel="ugc" href="https://civarchive.com/user/dvdufo">https://civarchive.com/user/dvdufo</a>
