Cosmos-Reason2-2B API: Pricing & Specs
Cosmos-Reason2-2B is an open-weight vision-language model that reads images alongside text.
What is Cosmos-Reason2-2B?
Cosmos-Reason2-2B is an open-weight vision-language model that reads images alongside text, published by NVIDIA with open weights at nvidia/Cosmos-Reason2-2B. LLM API does not route this model today, so there is no endpoint or code sample for it here. What this page does give you is the self-hosting picture: published weight sizes, the VRAM each quantisation needs and the commands to serve it yourself. Every figure is read from the public repository and refreshed weekly. At import it had 766,147 downloads on Hugging Face in the previous 30 days, under the other licence.
Can you self-host Cosmos-Reason2-2B?
No. We found no public weights for Cosmos-Reason2-2B on Hugging Face, so there is nothing to download, quantize or serve on your own GPUs: no VRAM budget, no vLLM or GGUF build to plan for. The only way to run it is over an API.

Use it if...
- You want to run Cosmos-Reason2-2B on your own hardware and keep every prompt inside your network
- The weights are published openly, so you can pin one checkpoint and keep it reproducible
- You want to fine-tune or quantise the model rather than accept a hosted configuration
- Your workload rewards deliberate step-by-step reasoning over fast replies
Avoid if...
- LLM API does not route this model today, so there is no endpoint here to call
- You have no GPU capacity: the VRAM figures below are the floor, not a suggestion
- You want zero operations — serving, scaling and upgrades are yours to run
- You need audio or video input; this checkpoint documents text and images only
