Cosmos inference recipes

NVIDIA Cosmos Predict 2.5 generates navigable world videos. The maintained example runs the 2B text-to-world checkpoint on a single GPU.

Pick a recipe and runtime

Start with the result you want, then choose one of the runtimes FastVideo actually maintains for it.

Setup

The generated commands expect a local clone:

git clone https://github.com/hao-ai-lab/FastVideo.git
cd FastVideo

Use Configuration for supported Python and CLI settings, Optimizations for attention and memory tradeoffs, and the support matrix for the supported model and optimization surface.

Troubleshooting

• World-generation prompts work best describing a scene and camera motion; the built-in prompt in the example is a known-good starting point.
• Gated or missing checkpoints: run huggingface-cli login and confirm you accepted the model's license on Hugging Face.

Evidence status

All recipes on this page are Source-backed: their commands, model IDs, and flags were validated against the checked-in FastVideo sources listed above (static validation). No runtime GPU validation is recorded for these recipes, so GPU model fit, memory use, throughput, and runtime duration are Unknown and deliberately not claimed. Runtime buttons show only the GPU counts configured in checked-in sources.
