Frequently Asked Questions about Llama 3.1 Nemotron Ultra 253B

How much does the Llama 3.1 Nemotron Ultra 253B API cost per 1M tokens?+

Llama 3.1 Nemotron Ultra 253B by NVIDIA is priced at $0.8 per 1M input tokens and $2.4 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.2 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.

Should I use a $20/month subscription or the Llama 3.1 Nemotron Ultra 253B 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 Llama 3.1 Nemotron Ultra 253B's context window?+

Llama 3.1 Nemotron Ultra 253B features a 128K tokens context window, which equals approximately 96,000 English words or ~256 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.

Can I run Llama 3.1 Nemotron Ultra 253B locally on my own GPU (Open Weights)?+

Yes, Llama 3.1 Nemotron Ultra 253B (253B) 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 Llama 3.1 Nemotron Ultra 253B 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 Llama 3.1 Nemotron Ultra 253B perform on coding and reasoning benchmarks?+

Llama 3.1 Nemotron Ultra 253B achieves a composite Intelligence Index of 54/100, scoring 52.8% on SWE-bench Verified, 66% on GPQA Diamond, 84% on MMLU-Pro, and 1362 pts on Chatbot Arena Elo.

What is Llama 3.1 Nemotron Ultra 253B best used for?+

Llama 3.1 Nemotron Ultra 253B is best suited for: empresarial datacenter inteligencia, automatizado code migrations, y de misión crítica razonamiento. Assessment: de NVIDIA abierto-weight heavyweight benchmark leader para alto-rendimiento empresarial infraestructura.
