ComfyUI Tutorial Series Ep 51: Nvidia Cosmos Predict2 Image & Video Models in Action

Описание: In episode 51 of the ComfyUI tutorial series, we take a detailed look at NVIDIA Cosmos Predict 2 models for both image and video generation. Learn how to set up the workflow in ComfyUI, download and organize the required models, and generate high-quality outputs using the 2B base version or larger GGUF variants like Q4 and Q8.

This episode covers both text-to-image and image-to-image workflows, how to manage denoise settings, and how to use helper tools like resolution calculators and image scaling nodes for better results. We also test out the video generation workflow, starting from an image and creating short video clips using the "video-to-world" node.

You'll see side-by-side comparisons of Cosmos 2B, 14B Q4/Q8, and popular models like Flux Dev, along with insights on which model performs better for different styles — including anime, oil painting, cartoon renders, and realism.

📌 What you’ll learn:
How to update ComfyUI for Cosmos support
Setup for text-to-image and image-to-image workflows
Using Cosmos models in GGUF format
Running the video generation workflow
Model comparison: Cosmos vs Flux for different styles
