Cosmos-Predict2 Image
NVIDIA’s Cosmos-Predict2 is a free AI toolset that turns text or media into physics-aware visuals with top performance on GPUs. With it, you can generate dynamic, high quality images from text or image inputs.
Overview
NVIDIA dropped a heavy hitter here. Cosmos-Predict2 is smart enough to keep movement grounded in real physics.
You can run it quick with the smaller 2B version or go all in with the 14B model for top-shelf quality.
ComfyUI natively supports NVIDIA’s Cosmos-Predict2 model family.
It's part of a suite called a “world model” built for stuff like robotics and self-driving. Works from text, images or even video to guess what happens next. NVIDIA made it free under its open model license which means yes you can use it for paid work... just don’t mess with the built-in safety guardrails or you’re out.
You’ll still need a strong GPU though. Think NVIDIA GB200 or a fat RTX card. That’s where the real cost lands.
All the models are optimized for NVIDIA hardware and come with inference scripts. You can test them out fast and even fine-tune them.
How to Use It
You can grab the code from GitHub or Hugging Face. It installs with pip or Docker. There are scripts ready to go for common jobs like text2image or video2world.
To use it through Hugging Face you’ll need a token and accept their license. But then you’re good to go.
Safety and Licensing
NVIDIA built guardrails in so you can’t generate just anything. It uses Llama Guard 3 to filter stuff and the license clearly says don’t disable that. If you follow the rules you can use it all you want even for business.

The 2B model’s small but mighty. Folks say it's super clear for its size and doesn’t mess up anatomy much. Not the fastest out there but it holds its own against base SDXL in how detailed and sharp it looks. It’s not great at photorealism but nails anything surreal or stylized.
The 14B model. More accurate and packs more detail but feels slow and not all that fun to look at. Weirdly better at abstract stuff than making pictures that feel good.
Filters. NSFW ones are tough but it's looser about things like weapons or made-up characters. Still swaps out celeb faces or turns them into artsy versions.
What really stands out is how easy it is to train. Folks say it's way easier to tweak than newer ones like HiDream or Flux. So yeah if you want to make your own styles it’s looking pretty solid.
People are torn on the style. Some say it looks plasticky like a Barbie render. Others think the polish is solid. Not much punch for photoreal lovers but it does weird fantasy stuff really well.
The crowd’s split. Some think it's all hype again not topping SDXL or Flux. But others think it might be the new go-to since it’s open-ish and flexible.
And yeah the whole "autoregressive" hype is still going. Some users say AR or hybrid setups might fix memory and long sequence stuff.
