## **Performance on RTX 5090**
> When using **HunyuanImage-2.1** with the **quantized encoder** + **quantized base model**,  
> the VRAM usage on an **NVIDIA RTX 5090** typically ranges between **26 GB and 30 GB** with average   
> 16 second inference time depending on resolution, batch size, and prompt complexity.
> **Reports that it works on 16gb VRAM GPU's**

⚠ **Important Note:**  
The **refiner** is still not implemented and is **not ready for use in ComfyUI**.  
However, the **distilled model now works in ComfyUI** with recommended settings of **8 steps / 1.5-2.5 CFG**.
