Output costs 4.0× the input price, so long replies drive the bill more than long prompts. If your requests share a long fixed prefix, such as a system prompt or tool definitions, caching cuts that part to 20% of the normal input price.

Context

Context window

Nemotron 3 Ultra accepts up to 202,800 tokens per request, roughly 152,100 English words or 304 pages. That budget is shared between your prompt and the reply, and no separate cap on the reply is published.

Filling the whole window with one prompt costs about $0.12 at list price, so for repeated long-document work, retrieval (sending only the relevant parts) or prompt caching is usually much cheaper.
