Frequently Asked Questions about Nemotron Cascade 2 30B A3B

How much does the Nemotron Cascade 2 30B A3B API cost per 1M tokens?+

Nemotron Cascade 2 30B A3B by NVIDIA is priced at $0.1 per 1M input tokens and $0.25 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.02 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.

Should I use a $20/month subscription or the Nemotron Cascade 2 30B A3B pay-as-you-go API?+

A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.

How many words and pages fit in Nemotron Cascade 2 30B A3B's context window?+

Nemotron Cascade 2 30B A3B features a 256K tokens context window, which equals approximately 192,000 English words or ~512 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.

Can I run Nemotron Cascade 2 30B A3B locally on my own GPU (Open Weights)?+

Yes, Nemotron Cascade 2 30B A3B (30B (3B active MoE)) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.

Does NVIDIA train on data sent to the Nemotron Cascade 2 30B A3B API, and is commercial use allowed?+

100% Isolated when self-hosted on private GPUs or VPC. License tier: Open-Weights Research & Commercial License. Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.

How does Nemotron Cascade 2 30B A3B perform on coding and reasoning benchmarks?+

Nemotron Cascade 2 30B A3B achieves a composite Intelligence Index of 46/100, scoring 39.5% on SWE-bench Verified, 55.2% on GPQA Diamond, 76% on MMLU-Pro, and 1295 pts on Chatbot Arena Elo.

What is Nemotron Cascade 2 30B A3B best used for?+

Nemotron Cascade 2 30B A3B is best suited for: en temps réel conversationnel agents, instant codage autocomplete, et faible-latence API services. Assessment: un ultra-rapide cascaded MoE qui sets un new vitesse standard pour 30B classe architectures.
