## In brief
NVIDIA Nemotron is not a chat app with a monthly plan. It is an open model family for agents, with a prototype API and self-hosting.


## Limits
The models can be self-hosted. The hosted prototype runs on build.nvidia.com. The topic page states up to 1 million tokens of context for the Nemotron 3 family; that is a family figure, not a separately confirmed context length for every model. No single NVIDIA token list price for production is published there. Production uses the named partner endpoints or self-hosted NIM. The topic page does not say whether prototype-API prompts are used for training.

## Pricing tiers
| Tier | Price | Period | What you get |
| --- | --- | --- | --- |
| Prototype API | free | free trial access, no token price | FAQ: 'All models offer a free trial tier with no credit card required.'; Base URL https://integrate.api.nvidia.com/v1, authentication with an NVIDIA API key; The same endpoints implement the OpenAI Chat Completions API; Example model on the Ultra page: nvidia/nemotron-3-ultra-550b-a55b |
| Production | contact sales | partner endpoint or self-hosted NIM | Ultra page: prototype on the free API endpoint, scale through partner endpoints or self-hosted deployments; The topic page does not publish one NVIDIA token price for the model family; Individual partner prices are those providers' prices, not an NVIDIA list price |
