|
|
|
## Model Overview |
|
- **Model Architecture:** Meta-Llama-3.1 |

|
- **Weight quantization:** FP8 |
|

|
- **Release Date:** 8/22/2024 |
|
- **Version:** 1.1 |
|
- **License(s):** [llama3.1](https://huggingface.co/meta-llama/Meta-Llama-3.1-8B/blob/main/LICENSE) |
|
- **Model Developers:** Neural Magic |
|
|
|
This model is a quantized version of [Meta-Llama-3.1-405B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3.1-405B-Instruct). |
|
It was evaluated on a several tasks to assess the its quality in comparison to the unquatized model, including multiple-choice, math reasoning, and open-ended text generation. |
|
Meta-Llama-3.1-405B-Instruct-FP8-dynamic achieves 99.0% recovery for the Arena-Hard evaluation, 100.0% for OpenLLM v1 (using Meta's prompting when available), 99.9% for OpenLLM v2, 100.2% for HumanEval pass@1, and 101.1% for HumanEval+ pass@1. |
|
|
|
### Model Optimizations |
|
|
|
This model was obtained by quantizing the weights and activations of [Meta-Llama-3.1-405B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3.1-405B-Instruct) to FP8 data type, ready for inference with vLLM built from source. |
|
This optimization reduces the number of bits per parameter from 16 to 8, reducing the disk size and GPU memory requirements by approximately 50%. In particular, this model can now be loaded and evaluated with a single node of 8xH100 GPUs, as opposed to multiple nodes. |
|
|
|
Only the weights and activations of the linear operators within transformers blocks are quantized. Symmetric per-channel quantization is applied, in which a linear scaling per output dimension maps the FP8 representations of the quantized weights and activations. Activations are also quantized on a per-token dynamic basis. |
|
[LLM Compressor](https://github.com/vllm-project/llm-compressor) is used for quantization. |
|
|
|
## Deployment |
|
|
|
### Use with vLLM |
|
|
|
This model can be deployed efficiently using the [vLLM](https://docs.vllm.ai/en/latest/) backend, as shown in the example below. |
|
|
|
```python |
|
from vllm import LLM, SamplingParams |
|
from transformers import AutoTokenizer |
|
|
|
model_id = "neuralmagic/Meta-Llama-3.1-405B-Instruct-FP8-dynamic" |
|
number_gpus = 8 |
|
|
|
sampling_params = SamplingParams(temperature=0.6, top_p=0.9, max_tokens=256) |
|
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id) |
|
|
|
messages = [ |
|
{"role": "system", "content": "You are a pirate chatbot who always responds in pirate speak!"}, |
|
{"role": "user", "content": "Who are you?"}, |
|
] |
|
|
|
prompts = tokenizer.apply_chat_template(messages, add_generation_prompt=True, tokenize=False) |
|
|
|
llm = LLM(model=model_id, tensor_parallel_size=number_gpus, max_model_len=4096) |
|
|
|
outputs = llm.generate(prompts, sampling_params) |
|
|
|
generated_text = outputs[0].outputs[0].text |
|
print(generated_text) |
|
``` |
|
|
|
vLLM aslo supports OpenAI-compatible serving. See the [documentation](https://docs.vllm.ai/en/latest/) for more details. |
|
|
|
## Creation |
|
|
|
This model was created by applying [LLM Compressor with calibration samples from UltraChat](https://github.com/vllm-project/llm-compressor/blob/sa/big_model_support/examples/big_model_offloading/big_model_w8a8_calibrate.py), as presented in the code snipet below. |

|
## Evaluation |
|
|
|
This model was evaluated on the well-known Arena-Hard, OpenLLM v1, OpenLLM v2, HumanEval, and HumanEval+ benchmarks. |
|
In all cases, model outputs were generated with the [vLLM](https://docs.vllm.ai/en/stable/) engine. |
|
|
|
Arena-Hard evaluations were conducted using the [Arena-Hard-Auto](https://github.com/lmarena/arena-hard-auto) repository. |
|
The model generated a single answer for each prompt form Arena-Hard, and each answer was judged twice by GPT-4. |
|
We report below the scores obtained in each judgement and the average. |
|
|
|
OpenLLM v1 and v2 evaluations were conducted using Neural Magic's fork of [lm-evaluation-harness](https://github.com/neuralmagic/lm-evaluation-harness/tree/llama_3.1_instruct) (branch llama_3.1_instruct). |
|
This version of the lm-evaluation-harness includes versions of MMLU, ARC-Challenge and GSM-8K that match the prompting style of [Meta-Llama-3.1-Instruct-evals](https://huggingface.co/datasets/meta-llama/Meta-Llama-3.1-405B-Instruct-evals) and a few fixes to OpenLLM v2 tasks. |
|
|
|
HumanEval and HumanEval+ evaluations were conducted using Neural Magic's fork of the [EvalPlus](https://github.com/neuralmagic/evalplus) repository. |
|
|
|
Detailed model outputs are available as HuggingFace datasets for [Arena-Hard](https://huggingface.co/datasets/neuralmagic/quantized-llama-3.1-arena-hard-evals), [OpenLLM v2](https://huggingface.co/datasets/neuralmagic/quantized-llama-3.1-leaderboard-v2-evals), and [HumanEval](https://huggingface.co/datasets/neuralmagic/quantized-llama-3.1-humaneval-evals). |
