Model Overview

Description:

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 1 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.

This model was trained using RLHF (specifically, REINFORCE), Llama-3.1-Nemotron-70B-Reward and HelpSteer2-Preference prompts on a Llama-3.1-70B-Instruct model as the initial policy.

If you prefer to use the model in the HuggingFace Transformers codebase, we have done a model conversion format into Llama-3.1-Nemotron-70B-Instruct-HF .

Try hosted inference for free at build.nvidia.com - it comes with an OpenAI-compatible API interface.

See details on our paper at https://arxiv.org/abs/2410.01257 - as a preview, this model can correctly the question How many r in strawberry? without specialized prompting or additional reasoning tokens:

A sweet question!
Let’s count the “R”s in “strawberry”:
1. S
2. T
3. R
4. A
5. W
6. B
7. E
8. R
9. R
10. Y
There are **3 “R”s** in the word “strawberry”.

Note: This model is a demonstration of our techniques for improving helpfulness in general-domain instruction following. It has not been tuned for performance in specialized domains such as math.

Usage:

We demonstrate inference using NVIDIA NeMo Framework, which allows hassle-free model deployment based on NVIDIA TRT-LLM, a highly optimized inference solution focussing on high throughput and low latency.

Pre-requisite: You would need at least a machine with 4 40GB or 2 80GB NVIDIA GPUs, and 150GB of free disk space.

Please sign up to get free and immediate access to NVIDIA NeMo Framework container. If you don’t have an NVIDIA NGC account, you will be prompted to sign up for an account before proceeding.
If you don’t have an NVIDIA NGC API key, sign into NVIDIA NGC, selecting organization/team: ea-bignlp/ga-participants and click Generate API key. Save this key for the next step. Else, skip this step.

On your machine, docker login to nvcr.io using

docker login nvcr.io
Username: $oauthtoken
Password: <Your Saved NGC API Key>

Download the required container

docker pull nvcr.io/nvidia/nemo:24.05.llama3.1

Download the checkpoint

git lfs install
git clone https://huggingface.co/nvidia/Llama-3.1-Nemotron-70B-Instruct

Run Docker container (In addition, to use Llama3.1 tokenizer, you need to export HF_HOME=<YOUR_HF_HOME_CONTAINING_TOKEN_WITH_LLAMA3.1_70B_ACCESS>)

docker run --gpus all -it --rm --shm-size=150g -p 8000:8000 -v ${PWD}/Llama-3.1-Nemotron-70B-Instruct:/opt/checkpoints/Llama-3.1-Nemotron-70B-Instruct,${HF_HOME}:/hf_home -w /opt/NeMo nvcr.io/nvidia/nemo:24.05.llama3.1

Within the container, start the server in the background. This step does both conversion of the nemo checkpoint to TRT-LLM and then deployment using TRT-LLM. For an explanation of each argument and advanced usage, please refer to NeMo FW Deployment Guide

HF_HOME=/hf_home python scripts/deploy/nlp/deploy_inframework_triton.py --nemo_checkpoint /opt/checkpoints/Llama-3.1-Nemotron-70B-Instruct --model_type="llama" --triton_model_name nemotron --triton_http_address 0.0.0.0 --triton_port 8000 --num_gpus 2 --max_input_len 3072 --max_output_len 1024 --max_batch_size 1 &

Once the server is ready (i.e. when you see this messages below), you are ready to launch your client code
