- text: "A crystalline waterfall stands partially frozen, its edges draped with translucent ice that catches the sunlight in prisms of blue and silver. Below, a half-frozen pool spreads out, bordered by delicate ice formations. Through the fresh snow, a red fox moves gracefully, its russet coat vibrant against the white landscape, leaving perfect star-shaped prints behind as steam rises from its breath in the crisp winter air. The scene is wrapped in snow-muffled silence, broken only by the gentle murmur of water still flowing beneath the ice.

# **gguf/fp8 quantized version of video2world and text2world (test in progress)**

![screenshot](https://raw.githubusercontent.com/calcuis/comfy/master/cosmos.gif)

## **setup (once)**
- drag Cosmos-1_0-Diffusion-7B-Video2World_fp8_e4m3fn.safetensors [[7.24GB](https://huggingface.co./calcuis/cosmos/blob/main/Cosmos-1_0-Diffusion-7B-Video2World_fp8_e4m3fn.safetensors)] or/and Cosmos-1_0-Diffusion-7B-Text2World_fp8_e4m3fn.safetensors [[7.24GB](https://huggingface.co./calcuis/cosmos/blob/main/Cosmos-1_0-Diffusion-7B-Text2World_fp8_e4m3fn.safetensors)] to > ./ComfyUI/models/diffusion_models
- drag oldt5_xxl_fp8_e4m3fn.safetensors [[4.9GB](https://huggingface.co./calcuis/cosmos/blob/main/oldt5_xxl_fp8_e4m3fn.safetensors)] to > ./ComfyUI/models/text_encoders
- drag cosmos_cv8x8x8_1.0_vae_bf16.safetensors [[211MB](https://huggingface.co./calcuis/cosmos/blob/main/cosmos_cv8x8x8_1.0_vae_bf16.safetensors)] to > ./ComfyUI/models/vae

## **run it straight (no installation needed way)**
- run the .bat file in the main directory (assuming you are using the gguf-node [pack](https://github.com/calcuis/gguf/releases) below)
- drag the workflow json file (below), or the sample webp file, to > your browser

### **workflow**
- example workflow for [text2world](https://huggingface.co./calcuis/cosmos/blob/main/workflow-text2world.json)
- example workflow for [video2world](https://huggingface.co./calcuis/cosmos/blob/main/workflow-video2world.json)

### **review**
- working roughly; but not very stable/consistent for the time being
- gguf file might not work; if so, please wait for the code update
- btw, you are able to replicate the conversion step and get exactly the same file with tools in gguf node (this point is not directly related to the model)
