+> This repository is a community-driven quantized version of the original model [`meta-llama/Meta-Llama-3.1-405B-Instruct`](https://huggingface.co/meta-llama/Meta-Llama-3.1-405B-Instruct) which is the FP16 half-precision official version released by Meta AI.
+
+## Model Information
+
+The Meta Llama 3.1 collection of multilingual large language models (LLMs) is a collection of pretrained and instruction tuned generative models in 8B, 70B and 405B sizes (text in/text out). The Llama 3.1 instruction tuned text only models (8B, 70B, 405B) are optimized for multilingual dialogue use cases and outperform many of the available open source and closed chat models on common industry benchmarks.
+
+This repository contains [`meta-llama/Meta-Llama-3.1-405B-Instruct`](https://huggingface.co/meta-llama/Meta-Llama-3.1-405B-Instruct) quantized using [AutoGPTQ](https://github.com/AutoGPTQ/AutoGPTQ) from FP16 down to INT4 using the GPTQ kernels performing zero-point quantization with a group size of 128.
+
+## Model Usage
+
+> [!NOTE]
+> In order to run the inference with Llama 3.1 405B Instruct GPTQ in INT4, around 203 GiB of VRAM are needed only for loading the model checkpoint, without including the KV cache or the CUDA graphs, meaning that there should be a bit over that VRAM available.
+
+In order to use the current quantized model, support is offered for different solutions as `transformers`, `autogptq`, or `text-generation-inference`.
+
+### 🤗 transformers
+
+In order to run the inference with Llama 3.1 405B Instruct GPTQ in INT4, both `torch` and `autogptq` need to be installed as:
+
+```bash
+pip install "torch>=2.2.0,<2.3.0" --upgrade
+pip install auto-gptq --no-build-isolation
+```
+
+Otherwise, running the model may fail, since the AutoGPTQ kernels are built with PyTorch 2.2.1, meaning that those will break with PyTorch 2.3.0.
+
+Then, the latest version of `transformers` need to be installed including the `accelerate` extra, being 4.43.0 or higher, as:
+
+```bash
+pip install "transformers[accelerate]>=4.43.0" --upgrade
+```
+
+Finally, in order to use `autogptq`, `optimum` also needs to be installed:
+
+```bash
+pip install optimum --upgrade
+```
+
+To run the inference on top of Llama 3.1 405B Instruct GPTQ in INT4 precision, the GPTQ model can be instantiated as any other causal language modeling model via `AutoModelForCausalLM` and run the inference normally.
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "hugging-quants/Meta-Llama-3.1-405B-Instruct-GPTQ-INT4"
+prompt = [
+  {"role": "system", "content": "You are a helpful assistant, that responds as a pirate."},
+  {"role": "user", "content": "What's Deep Learning?"},
+]
+
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+
+inputs = tokenizer.apply_chat_template(
+  prompt,
+  tokenize=True,
+  add_generation_prompt=True,
+  return_tensors="pt",
+  return_dict=True,
+).to("cuda")
+
+model = AutoModelForCausalLM.from_pretrained(
+  model_id,
+  torch_dtype=torch.float16,
+  low_cpu_mem_usage=True,
+  device_map="auto",
+)
+
+outputs = model.generate(**inputs, do_sample=True, max_new_tokens=256)
+print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
+```
+
+### AutoGPTQ
+
+Alternatively, one may want to run that via `AutoGPTQ` even though it's built on top of 🤗 `transformers`, which is the recommended approach instead as described above.
+
+In order to run the inference with Llama 3.1 405B Instruct GPTQ in INT4, both `torch` and `autogptq` need to be installed as:
+
+```bash
+pip install "torch>=2.2.0,<2.3.0" --upgrade
+pip install auto-gptq --no-build-isolation
+```
+
+Otherwise, running the model may fail, since the AutoGPTQ kernels are built with PyTorch 2.2.1, meaning that those will break with PyTorch 2.3.0.
+
+Then, the latest version of `transformers` need to be installed including the `accelerate` extra, being 4.43.0 or higher, as:
+
+```bash
+pip install "transformers[accelerate]>=4.43.0" --upgrade
+```
+
+Finally, in order to use `autogptq`, `optimum` also needs to be installed:
+
+```bash
+pip install optimum --upgrade
+```
+
+And then run it as follows:
+
+```python
+import torch
+from auto_gptq import AutoGPTQForCausalLM
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "hugging-quants/Meta-Llama-3.1-405B-Instruct-GPTQ-INT4"
+prompt = [
+  {"role": "system", "content": "You are a helpful assistant, that responds as a pirate."},
+  {"role": "user", "content": "What's Deep Learning?"},
+]
+
+tokenizer = AutoTokenizer.from_pretrained(model_id)
+
+inputs = tokenizer.apply_chat_template(prompt, tokenize=True, add_generation_prompt=True, return_tensors="pt").cuda()
+
+model = AutoGPTQForCausalLM.from_pretrained(
+  model_id,
+  torch_dtype=torch.float16,
+  low_cpu_mem_usage=True,
+  device_map="auto",
+)
+
+outputs = model.generate(inputs, do_sample=True, max_new_tokens=256)
+print(tokenizer.batch_decode(outputs, skip_special_tokens=True))
+```
+
+The AutoGPTQ script has been adapted from [AutoGPTQ/examples/quantization/basic_usage.py](https://github.com/AutoGPTQ/AutoGPTQ/blob/main/examples/quantization/basic_usage.py).
+
+### 🤗 Text Generation Inference (TGI)
+
+Coming soon!
+
+## Quantization Reproduction
+
+> [!NOTE]
+> In order to quantize Llama 3.1 405B Instruct using AutoGPTQ, you will need to use an instance with at least enough CPU RAM to fit the whole model i.e. ~800GiB, and an NVIDIA GPU with 80GiB of VRAM to quantize it.
+
+In order to quantize Llama 3.1 405B Instruct, first install `torch` and `autoqptq` as follows:
+
+```bash
+pip install "torch>=2.2.0,<2.3.0" --upgrade
+pip install auto-gptq --no-build-isolation
+```
+
+Otherwise the quantization may fail, since the AutoGPTQ kernels are built with PyTorch 2.2.1, meaning that those will break with PyTorch 2.3.0.
+
+Then install the latest version of `transformers` as follows:
+
+```bash
+pip install "transformers>=4.43.0" --upgrade
+```
+
+Finally, in order to use `autogptq`, `optimum` also needs to be installed:
+
+```bash
+pip install optimum --upgrade
+```
+
+And then, run the following script, adapted from [AutoGPTQ/examples/quantization/basic_usage.py](https://github.com/AutoGPTQ/AutoGPTQ/blob/main/examples/quantization/basic_usage.py).
+
+```python

+    input_ids = encodings.input_ids[:, i:j]
+    attention_mask = torch.ones_like(input_ids)
+    calibration_samples.append({"input_ids": input_ids, "attention_mask": attention_mask})
+
+quantize_config = BaseQuantizeConfig(
+    bits=4,  # quantize model to 4-bit
+    group_size=128,  # it is recommended to set the value to 128
+    desc_act=True,  # set to False can significantly speed up inference but the perplexity may slightly bad
+    sym=True,  # using symmetric quantization so that the range is symmetric allowing the value 0 to be precisely represented (can provide speedups)
+    damp_percent=0.1,  # see https://github.com/AutoGPTQ/AutoGPTQ/issues/196
+)
+
+# load un-quantized model, by default, the model will always be loaded into CPU memory
+print("Load unquantized model...")
+model = AutoGPTQForCausalLM.from_pretrained(pretrained_model_dir, quantize_config)
+
+# quantize model, the examples should be list of dict whose keys can only be "input_ids" and "attention_mask"
+print("Quantize model with calibration samples...")
+model.quantize(calibration_samples)
+
+# save quantized model using safetensors
+model.save_quantized(quantized_model_dir, use_safetensors=True)
