Llama2-70B-SteerLM-Chat

License

The use of this model is governed by the Llama 2 Community License Agreement

Description:

Llama2-70B-SteerLM-Chat is a 70 billion parameter generative language model instruct-tuned using SteerLM technique. It takes input with context length up to 4,096 tokens. The model has been aligned using the SteerLM method developed by NVIDIA to allow for user control of model outputs (in creativity, complexity and verbosity) during inference while having simplified training compared to RLHF techniques.

Llama2-70B-SteerLM-Chat reaches 7.54 on MT Bench, the highest among commercial-use-friendly models trained on open-source datasets based on MT Bench Leaderboard as of 15 Nov 2023.

Try this model instantly for free hosted by us at NVIDIA AI Playground. You can use this in the provided UI or through a limited access API (up to 10, 000 requests within 30 days). If you would need more requests, we demonstrate how you can set up an inference server below.

SteerLM Paper: SteerLM: Attribute Conditioned SFT as an (User-Steerable) Alternative to RLHF

Llama2-70B-SteerLM-Chat is trained with NVIDIA NeMo, an end-to-end, cloud-native framework to build, customize, and deploy generative AI models anywhere. It includes training and inferencing frameworks, guardrailing toolkits, data curation tools, and pretrained models, offering enterprises an easy, cost-effective, and fast way to adopt generative AI.

You can train the model using NeMo Aligner following SteerLM training user guide or run inference based on steps below.

Model Architecture:

Architecture Type: Transformer

Network Architecture: Llama 2

The SteerLM method involves the following key steps:

  1. Train an attribute prediction model on human annotated data to evaluate response quality.
  2. Use this model to annotate diverse datasets and enrich training data.
  3. Perform conditioned fine-tuning to align responses with specified combinations of attributes.

Llama2-70B-SteerLM-Chat applies this technique on top of the Llama 2 70B Foundational model architecture. It was pretrained on internet-scale data and then aligned using Open Assistant and HelpSteer.

Software Integration:

Runtime Engine(s): NVIDIA AI Enterprise

Toolkit: NeMo Framework

Supported Hardware Architecture Compatibility: H100, A100 80GB, A100 40GB

Steps to run inference:

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 300GB of free disk space.

  1. 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.

  2. 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.

  3. On your machine, docker login to nvcr.io using

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

  4. Download the required container

    docker pull nvcr.io/ea-bignlp/ga-participants/nemofw-inference:23.10

  5. Download the checkpoint

    git lfs install
git clone https://huggingface.co/nvidia/Llama2-70B-SteerLM-Chat

  6. Convert checkpoint into nemo format

    cd Llama2-70B-SteerLM-Chat/Llama2-70B-SteerLM-Chat
tar -cvf Llama2-70B-SteerLM-Chat.nemo .
mv Llama2-70B-SteerLM-Chat.nemo ../
cd ..
rm -r Llama2-70B-SteerLM-Chat

  7. Run Docker container

    docker run --gpus all -it --rm --shm-size=300g -p 8000:8000 -v ${PWD}/Llama2-70B-SteerLM-Chat.nemo:/opt/checkpoints/Llama2-70B-SteerLM-Chat.nemo -w /opt/NeMo nvcr.io/ea-bignlp/ga-participants/nemofw-inference:23.10

  8. 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

    python scripts/deploy/deploy_triton.py --nemo_checkpoint /opt/checkpoints/Llama2-70B-SteerLM-Chat.nemo --model_type="llama" --triton_model_name Llama2-70B-SteerLM-Chat --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 &

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

PROMPT_TEMPLATE = """<extra_id_0>System

"""

question = "Write a poem on NVIDIA in the style of Shakespeare"
prompt = PROMPT_TEMPLATE.format(prompt=question)
print(prompt)

nq = NemoQuery(url="localhost:8000", model_name="Llama2-70B-SteerLM-Chat")
output = nq.query_llm(prompts=[prompt], max_output_token=15, top_k=1, top_p=0.0, temperature=1.0)

#this container currently does not support stop words but you do something like this as workaround
output = output[0][0].split("\n<extra_id_1>")[0]
print(output)

  10. If you would support multi-turn conversations or adjust attribute values at inference time, here is some guidance:

    Default template for Single Turn

    <extra_id_0>System
A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
<extra_id_1>User
{prompt 1}
<extra_id_1>Assistant
<extra_id_2>quality:4,toxicity:0,humor:0,creativity:0,helpfulness:4,correctness:4,coherence:4,complexity:4,verbosity:4

    Default template for Multi-Turn

    <extra_id_0>System
A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
<extra_id_1>User
{prompt 1}
<extra_id_1>Assistant
<extra_id_2>quality:4,toxicity:0,humor:0,creativity:0,helpfulness:4,correctness:4,coherence:4,complexity:4,verbosity:4
{response 1}
<extra_id_1>User
{prompt 2}
<extra_id_1>Assistant
<extra_id_2>quality:4,toxicity:0,humor:0,creativity:0,helpfulness:4,correctness:4,coherence:4,complexity:4,verbosity:4

    Each of the attributes (e.g. creativity, complexity and verbosity) can receive integer values in the range [0, 1, 2, 3, 4].

Intended use

The SteerLM-Llama2-70B model is for users who want to customize a model’s response during inference.

Ethical use: Technology can have a profound impact on people and the world, and NVIDIA is committed to enabling trust and transparency in AI development. NVIDIA encourages users to adopt principles of AI ethics and trustworthiness to guide your business decisions by following the guidelines in the Llama 2 Community License Agreement.

Limitations

The model was trained on the data that contains toxic language and societal biases originally crawled from the Internet. Therefore, the model may amplify those biases and return toxic responses especially when prompted with toxic prompts.

The model may generate answers that may be inaccurate, omit key information, or include irrelevant or redundant text producing socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive.

We recommend deploying the model with NeMo Guardrails to mitigate these potential issues.
