Guides for this model

nvidia | 131,072 token context | $1.20/M input, $1.20/M output. Llama-3.1-Nemotron-70B-Instruct is a large language model customized by NVIDIA to improve the helpfulness of LLM generated responses to user queries. This model reaches Arena Hard of 85.0, AlpacaEval 2 LC of 57.6 and GPT-4-Turbo MT-Bench of 8.98, which are known to be predictive of LMSys Chatbot Arena Elo. As of 16th Oct 2024, this model is #1 on all three automatic alignment benchmarks (verified tab for AlpacaEval 2 LC), edging out strong frontier models such as GPT-4o and Claude 3.5 Sonnet.
Llama 3.1 Nemotron 70B Instruct is Meta's Llama 3.1 70B fine-tuned by NVIDIA specifically to make responses more helpful and better aligned with what users actually want. At release it topped all three major automatic alignment benchmarks, outscoring GPT-4o and Claude 3.5 Sonnet on those measures. It suits anyone who needs a capable, instruction-following model via API at a predictable per-token rate.

Known for

  • Topped Arena Hard, AlpacaEval 2 LC and MT-Bench alignment benchmarks at release
  • NVIDIA alignment tuning aimed squarely at response helpfulness over raw capability
  • 128K token context window handles long documents and extended conversations
  • Strong instruction-following derived from Llama 3.1 70B base

Watch out for

  • Weights are not public; you use it through an API only, no local deployment.
  • At $1.20 per million tokens each way, costs can climb on high-volume workloads.
  • Benchmark lead was measured at a specific date; the landscape has moved since.

Prompts to try

Rewrite for clarity
Here is a paragraph from an internal policy document. Rewrite it so a new employee with no legal background can understand it in one read. Keep every obligation intact but cut jargon and passive voice. Paragraph: 'All personnel are required to ensure that compliance with applicable data retention schedules is maintained in accordance with jurisdictional regulatory frameworks as periodically amended.'
Plan a difficult conversation
I need to tell a long-standing freelance contractor that we are ending the relationship because their work quality has declined, not because of budget. They are likely to take it personally. Give me a structured plan for the conversation: what to say first, how to handle pushback, and how to close it respectfully.
Stress-test an argument
I am going to make an argument and I want you to steelman the strongest possible objection to it, then tell me honestly whether the objection or the original argument is more persuasive and why. My argument: remote work permanently reduces junior employees' career growth because informal mentorship and osmotic learning disappear.

Questions people ask

Can I run Nemotron 70B locally?
No. NVIDIA has not released the weights publicly, so the model is API-only and cannot be downloaded or run on your own hardware.
What does it cost and how long is the context?
Pricing is $1.20 per million tokens for both input and output, with a 131,072-token context window.
How does this differ from standard Llama 3.1 70B?
NVIDIA fine-tuned the base Llama 3.1 70B specifically for helpfulness and alignment, which pushed it above the base model on instruction-following benchmarks at the time of release.
Captain's verdict
A well-tuned 70B that punched above its weight class on alignment benchmarks at launch — solid for instruction-heavy work, if you can accept API-only access.
Captain writes these notes from the model's own description and model card. Prices and context sizes are the provider's at the time of writing and can change.

How this score adds up
This model has no popularity data from any source yet, so it carries a stand-in number below 7,000° that keeps the lists complete. It never ranks above a model with data. The breakdown appears here as soon as a source reports it.
Glossary: the terms used here
Heat score
One number for how much a model is used and wanted right now, from 0° to 9,999°. Every list on this site that says hottest is sorted by it and nothing else.
Floor
The 7,000° every model with real data starts from. The scale runs from 0° to 9,999°; the part below the floor is reserved for stand-ins (models without data), so that a model with data always ranks above one without. The floor is the same for everyone and decides nothing; the degrees above it are the measurement.
Download-equivalents
Everything the score treats as a download, added up: downloads themselves, each torrent seeder as 1,000, each AI Horde image and each run on a generation site as one.
Log scale
Counting by tens, not by ones: going from 1,000 to 10,000 downloads adds the same degrees as going from 10,000 to 100,000. It keeps giants from crowding out everything else.
Likes
Thumbs up and likes from every source, worth half a download each on the log scale.
Adoption rate
How many downloads a day a model gets right now, from the difference between two readings of a source. A quarter of the weight of the download term.
Measured and estimated
Measured means two readings of a source exist and the difference is real. Estimated means only today's total is known and the past is spread over the model's life; the site says which one it is showing.
Seeder
Someone who keeps a copy of the weights online for others to download over a torrent, or a hosted mirror doing the same. Each one counts as 1,000 downloads.
AI Horde
A volunteer network that generates images for free on donated computers. The number of images it has made with a model is public, and each counts as one download.
Generation sites
Sites that host their own copies of a model and let people generate with it, such as PixAI, SeaArt and Yodayo. Their downloads count like Civitai's and each generation run as one download.
OpenRouter tokens
A text model served through an API, such as Claude or GPT, has no weights to download, so its usage is measured in tokens: the pieces of text it read and wrote through OpenRouter, a gateway many apps use, over the last 30 days. Every 10,000,000 tokens count as one download. Source: OpenRouter (openrouter.ai/rankings), CC BY 4.0.
Full model (checkpoint)
The weights themselves, the file that generates on its own. It gets a bonus because add-ons depend on it.
LoRA and embedding
Small add-on files that steer someone else's weights toward a style, a character or a concept. They cannot run alone.
Family and weights
The base a model is built on, such as SD 1.5, SDXL, Flux or Wan. Every model inherits the release date of its family's weights.
Age
Degrees taken off for how long ago the family's weights came out: 150° a year, up to 750°. It keeps old downloads that had years to pile up from freezing the top of the list.
Family boost
A small, bounded nudge for LoRAs of a family this site is pushing forward right now, always listed in the breakdown.
Stand-in score
A stable number below the floor given to a model no source reports on yet, so lists stay complete. It never ranks above a model with data.
New! (grace period)
A model less than 7 days old shows New! instead of a score and holds no place in the rankings. Its score is computed from day one, but a model one day old grows faster than anything, so without the wait the week's #1 would always be whatever came out yesterday rather than what held up for a week.
Trend
How a model's growth over a period compares with the typical model's growth over the same period. Faster than typical reads as a rise, slower as a fall.
Typical model
The middle of the catalog: half the models with a figure grew faster over the period, half slower.
