+# Llama-3-8B-Instruct-GPTQ-4-Bit
+- Original Model creator: [Meta Llama from Meta](https://huggingface.co/meta-llama)
+- Original model: [meta-llama/Meta-Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct)
+- Built with Meta Llama 3
+- Quantized by [Astronomer](https://astronomer.io)
+
+# Important Note About Serving with vLLM & oobabooga/text-generation-webui
+- For loading this model onto vLLM, make sure all requests have `"stop_token_ids":[128001, 128009]` to temporarily address the non-stop generation issue.
+   - vLLM does not yet respect `generation_config.json`.
+   - vLLM team is working on a a fix for this https://github.com/vllm-project/vllm/issues/4180
+- For oobabooga/text-generation-webui
+  - Load the model via AutoGPTQ, with `no_inject_fused_attention` enabled. This is a bug with AutoGPTQ library.
+  - Under `Parameters` -> `Generation` -> `Skip special tokens`: turn this off (deselect)
+  - Under `Parameters` -> `Generation` -> `Custom stopping strings`: add `"<|end_of_text|>","<|eot_id|>"` to the field

+## Description
+
+This repo contains 4 Bit quantized GPTQ model files for [meta-llama/Meta-Llama-3-8B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-8B-Instruct).
+
+This model can be loaded with less than 6 GB of VRAM (huge reduction from the original 16.07GB model) and can be served lightning fast with the cheapest Nvidia GPUs possible (Nvidia T4, Nvidia K80, RTX 4070, etc).
+
+The 4 bit GPTQ quant has small quality degradation from the original `bfloat16` model but can be served on much smaller GPUs with maximum improvement in latency and throughput.
+
+<!-- description end -->
+
+## GPTQ Quantization Method
+- This model is quantized by utilizing the AutoGPTQ library, following best practices noted by [GPTQ paper](https://arxiv.org/abs/2210.17323)
+- Quantization is calibrated and aligned with random samples from the specified dataset (wikitext for now) for minimum accuracy loss.

+| Branch | Bits | Group Size | Act Order | Damp % | GPTQ Dataset | Sequence Length | VRAM Size | ExLlama | Description |
+| ------ | ---- | -- | --------- | ------ | ------------ | ------- | ---- | ------- | ---- |
+| [main](https://huggingface.co/astronomer-io/Llama-3-8B-Instruct-GPTQ-4-Bit/tree/main) | 4 | 128 | Yes | 0.1 | [wikitext](https://huggingface.co/datasets/wikitext/viewer/wikitext-2-v1/test) | 8192 | 5.74 GB | Yes | 4-bit, with Act Order and group size 128g. Smallest model possible with small accuracy loss | 
+| More variants to come | TBD | TBD | TBD | TBD | TBD | TBD | TBD | TBD | May upload additional variants of GPTQ 4 bit models in the future using different parameters such as 128g group size and etc. |
+
+## Serving this GPTQ model using vLLM
+Tested serving this model via vLLM using an Nvidia T4 (16GB VRAM).
+
+Tested with the below command
+```
+python -m vllm.entrypoints.openai.api_server --model astronomer-io/Llama-3-8B-Instruct-GPTQ-4-Bit --max-model-len 8192 --dtype float16
+```
+For the non-stop token generation bug, make sure to send requests with `stop_token_ids":[128001, 128009]` to vLLM endpoint
+Example:
+```json
+{
+    "model": "astronomer-io/Llama-3-8B-Instruct-GPTQ-4-Bit",
+    "messages": [
+        {"role": "system", "content": "You are a helpful assistant."},
+        {"role": "user", "content": "Who created Llama 3?"}
+        ],
+    "max_tokens": 2000,
+    "stop_token_ids":[128001,128009]
+}
+```
+### Prompt Template
+```
+<|begin_of_text|><|start_header_id|>user<|end_header_id|>
+{{prompt}}<|eot_id|>
+<|start_header_id|>assistant<|end_header_id|>
+```
