# Llama-3.1-8B-Instruct-FP8-block |
|
|
|
|
|
## Model Overview |
|
|
- **Model Architecture:** LlamaForCausalLM |
|
|
- **Input:** Text |
|
|
- **Output:** Text |
|
|
- **Model Optimizations:** |
|
|
- **Weight quantization:** FP8 |
|
|
- **Activation quantization:** FP8 |
|
|
- **Release Date:** |
|
|
- **Version:** 1.0 |
|
|

|
|
|
|
|
Quantized version of [meta-llama/Llama-3.1-8B-Instruct](https://huggingface.co/meta-llama/Llama-3.1-8B-Instruct). |
|
|
|
|
|
### Model Optimizations |
|
|
|
|
|
This model was obtained by quantizing the weights and activations of [meta-llama/Llama-3.1-8B-Instruct](https://huggingface.co/meta-llama/Llama-3.1-8B-Instruct) to FP8 data type. |
|
|
This optimization reduces the number of bits per parameter from 16 to 8, reducing the disk size and GPU memory requirements by approximately 50%. |
|
|
Only the weights and activations of the linear operators within transformers blocks of the language model are quantized. |
|
|
|
|
|
## Deployment |
|
|
|
|
|
### Use with vLLM |
|
|
|
|
|
1. Initialize vLLM server: |
|
|
``` |
|
|
vllm serve RedHatAI/Llama-3.1-8B-Instruct-FP8-block --tensor_parallel_size 1 |
|
|
``` |
|
|
|
|
|
2. Send requests to the server: |
|
|
|
|
|
```python |
|
|
from openai import OpenAI |
|
|
|
|
|
# Modify OpenAI's API key and API base to use vLLM's API server. |
|
|
openai_api_key = "EMPTY" |
|
|
openai_api_base = "http://<your-server-host>:8000/v1" |
|
|
|
|
|
client = OpenAI( |
|
|
api_key=openai_api_key, |
|
|
base_url=openai_api_base, |
|
|
) |
|
|
|
|
|
model = "RedHatAI/Llama-3.1-8B-Instruct-FP8-block" |
|
|
|
|
|
|
|
|
messages = [ |
|
|
{"role": "user", "content": "Explain quantum mechanics clearly and concisely."}, |
|
|
] |
|
|
|
|
|
outputs = client.chat.completions.create( |
|
|
model=model, |
|
|
messages=messages, |
|
|
) |
|
|
|
|
|
generated_text = outputs.choices[0].message.content |
|
|
print(generated_text) |
|
|
``` |
|
|
|
|
|
## Creation |
|
|
|
|
|
This model was quantized using the [llm-compressor](https://github.com/vllm-project/llm-compressor) library as shown below. |
|
|
|
|

|
|
<summary>Creation details</summary> |
|
|
|
|
|
```python |
|
|
from transformers import AutoProcessor, LlamaForCausalLM |
|
|
|
|
|
from llmcompressor import oneshot |
|
|
from llmcompressor.modeling import replace_modules_for_calibration |

|
|

|
|

|

|
|
|
|
|
# Configure the quantization algorithm and scheme. |
|
|
# In this case, we: |
|

|

|

# Save to disk in compressed-tensors format. |
|
|
SAVE_DIR = MODEL_ID.rstrip("/").split("/")[-1] + "-FP8-block" |
|

|
## Evaluation |
|
|
|
|
|
|
|
|
The model was evaluated on the OpenLLMv1 leaderboard task, using [lm-evaluation-harness](https://github.com/EleutherAI/lm-evaluation-harness), on reasoning tasks using [lighteval](https://github.com/huggingface/lighteval). |
|
|
[vLLM](https://docs.vllm.ai/en/stable/) was used for all evaluations. |
