Falcon 180B Chat - GPTQ


This repo contains GPTQ model files for Technology Innovation Institute's Falcon 180B Chat.

Multiple GPTQ parameter permutations are provided; see Provided Files below for details of the options provided, their parameters, and the software used to create them.


Transformers version 4.33.0 is required.

Due to the huge size of the model, the GPTQ has been sharded. This will break compatibility with AutoGPTQ, and therefore any clients/libraries that use AutoGPTQ directly.

But they work great loaded directly through Transformers - and can be served using Text Generation Inference!


Currently these GPTQs are known to work with:

User: Hello, Girafatron!

Provided files and GPTQ parameters

Multiple quantisation parameters are provided, to allow you to choose the best one for your hardware and requirements.

Each separate quant is in a different branch. See below for instructions on fetching from different branches.

All recent GPTQ files are made with AutoGPTQ, and all files in non-main branches are made with AutoGPTQ. Files in the main branch which were uploaded before August 2023 were made with GPTQ-for-LLaMa.

Explanation of GPTQ parameters
  • Bits: The bit size of the quantised model.
  • GS: GPTQ group size. Higher numbers use less VRAM, but have lower quantisation accuracy. "None" is the lowest possible value.
  • Act Order: True or False. Also known as desc_act. True results in better quantisation accuracy. Some GPTQ clients have had issues with models that use Act Order plus Group Size, but this is generally resolved now.
  • Damp %: A GPTQ parameter that affects how samples are processed for quantisation. 0.01 is default, but 0.1 results in slightly better accuracy.
  • GPTQ dataset: The dataset used for quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ dataset is not the same as the dataset used to train the model - please refer to the original model repo for details of the training dataset(s).
  • Sequence Length: The length of the dataset sequences used for quantisation. Ideally this is the same as the model sequence length. For some very long sequence models (16+K), a lower sequence length may have to be used. Note that a lower sequence length does not limit the sequence length of the quantised model. It only impacts the quantisation accuracy on longer inference sequences.
  • ExLlama Compatibility: Whether this file can be loaded with ExLlama, which currently only supports Llama models in 4-bit.
Branch Bits GS Act Order Damp % GPTQ Dataset Seq Len Size ExLlama Desc
main 4 128 Yes 0.1 wikitext 2048 94.25 GB No 4-bit, with Act Order and group size 128g. Higher quality than group_size=None, but also higher VRAM usage.
gptq-4bit--1g-actorder_True 4 None Yes 0.1 wikitext 2048 92.74 GB No 4-bit, with Act Order. No group size, to lower VRAM requirements.
gptq-3bit-128g-actorder_True 3 128 Yes 0.1 wikitext 2048 73.81 GB No 3-bit, so much lower VRAM requirements but worse quality than 4-bit. With group size 128g and act-order. Higher quality than 3bit-128g-False.
gptq-3bit--1g-actorder_True 3 None Yes 0.1 wikitext 2048 70.54 GB No 3-bit, so much lower VRAM requirements but worse quality than 4-bit. With no group size for lowest possible VRAM requirements. Lower quality than 3-bit 128g.

How to download from branches

  • In text-generation-webui, you can add :branch to the end of the download name, eg TheBloke/Falcon-180B-Chat-GPTQ:gptq-3bit--1g-actorder_True
  • With Git, you can clone a branch with:
git clone --single-branch --branch gptq-3bit--1g-actorder_True https://huggingface.co/TheBloke/Falcon-180B-Chat-GPTQ
  • In Python Transformers code, the branch is the revision parameter; see below.

How to easily download and use this model in text-generation-webui.

NOTE: I have not tested this model with Text Generation Webui. It should work through the Transformers Loader. It will not work through the AutoGPTQ loader, due to the files being sharded.

Please make sure you're using the latest version of text-generation-webui.

It is strongly recommended to use the text-generation-webui one-click-installers unless you're sure you know how to make a manual install.

  1. Click the Model tab.
  2. Under Download custom model or LoRA, enter TheBloke/Falcon-180B-Chat-GPTQ.
  • To download from a specific branch, enter for example TheBloke/Falcon-180B-Chat-GPTQ:gptq-3bit-128g-actorder_True
  • see Provided Files above for the list of branches for each option.
  1. Click Download.
  2. The model will start downloading. Once it's finished it will say "Done".
  3. Choose Loader: Transformers
  4. In the top left, click the refresh icon next to Model.
  5. In the Model dropdown, choose the model you just downloaded: Falcon-180B-Chat-GPTQ
  6. The model will automatically load, and is now ready for use!
  7. If you want any custom settings, set them and then click Save settings for this model followed by Reload the Model in the top right.
  • Note that you do not need to and should not set manual GPTQ parameters any more. These are set automatically from the file quantize_config.json.
  1. Once you're ready, click the Text Generation tab and enter a prompt to get started!

How to use this GPTQ model from Python code

Install the necessary packages

Requires: Transformers 4.33.0 or later, Optimum 1.12.0 or later, and AutoGPTQ.

pip3 install transformers>=4.33.0 optimum>=1.12.0
pip3 install auto-gptq --extra-index-url https://huggingface.github.io/autogptq-index/whl/cu118/  # Use cu117 if on CUDA 11.7

Transformers sample code

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

model_name_or_path = "TheBloke/Falcon-180B-Chat-GPTQ"

# To use a different branch, change revision
# For example: revision="gptq-3bit-128g-actorder_True"
model = AutoModelForCausalLM.from_pretrained(model_name_or_path,

tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, use_fast=True)

prompt = "Tell me about AI"
prompt_template=f'''User: {prompt}
Assistant: '''

print("\n\n*** Generate:")

input_ids = tokenizer(prompt_template, return_tensors='pt').input_ids.cuda()
output = model.generate(inputs=input_ids, do_sample=True, temperature=0.7, max_new_tokens=512)

# Inference can also be done using transformers' pipeline

print("*** Pipeline:")
pipe = pipeline(



The provided files have been tested with Transformers 4.33.0, and TGI 1.0.4.

Because they are sharded, they will not yet via AutoGPTQ. It is hoped support will be added soon.

Note: lack of support for AutoGPTQ doesn't affect your ability to load these models from Python code. It only affects third-party clients that might use AutoGPTQ.

Huggingface Text Generation Inference (TGI) is confirmed working as of version 1.0.4.

πŸš€ Falcon-180B-Chat

Falcon-180B-Chat is a 180B parameters causal decoder-only model built by TII based on Falcon-180B and finetuned on a mixture of Ultrachat, Platypus and Airoboros. It is made available under the Falcon-180B TII License and Acceptable Use Policy.

Paper coming soon 😊

πŸ€— To get started with Falcon (inference, finetuning, quantization, etc.), we recommend reading this great blogpost from HF or this one from the release of the 40B! Note that since the 180B is larger than what can easily be handled with transformers+acccelerate, we recommend using Text Generation Inference.

You will need at least 400GB of memory to swiftly run inference with Falcon-180B.

Why use Falcon-180B-chat?

  • ✨ You are looking for a ready-to-use chat/instruct model based on Falcon-180B.
  • It is the best open-access model currently available, and one of the best model overall. Falcon-180B outperforms LLaMA-2, StableLM, RedPajama, MPT, etc. See the OpenLLM Leaderboard.
  • It features an architecture optimized for inference, with multiquery (Shazeer et al., 2019).
  • It is made available under a permissive license allowing for commercial use.

πŸ’¬ This is a Chat model, which may not be ideal for further finetuning. If you are interested in building your own instruct/chat model, we recommend starting from Falcon-180B.

πŸ’Έ Looking for a smaller, less expensive model? Falcon-7B-Instruct and Falcon-40B-Instruct are Falcon-180B-Chat's little brothers!

πŸ’₯ Falcon LLMs require PyTorch 2.0 for use with transformers!

Model Details

Model Description

Model Source

  • Paper: coming soon.


See the acceptable use policy.

Direct Use

Falcon-180B-Chat has been finetuned on a chat dataset.

Out-of-Scope Use

Production use without adequate assessment of risks and mitigation; any use cases which may be considered irresponsible or harmful.

Bias, Risks, and Limitations

Falcon-180B-Chat is mostly trained on English data, and will not generalize appropriately to other languages. Furthermore, as it is trained on a large-scale corpora representative of the web, it will carry the stereotypes and biases commonly encountered online.


We recommend users of Falcon-180B-Chat to develop guardrails and to take appropriate precautions for any production use.

How to Get Started with the Model

To run inference with the model in full bfloat16 precision you need approximately 8xA100 80GB or equivalent.

from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch

model = "tiiuae/falcon-180b-chat"

tokenizer = AutoTokenizer.from_pretrained(model)
pipeline = transformers.pipeline(
sequences = pipeline(
   "Girafatron is obsessed with giraffes, the most glorious animal on the face of this Earth. Giraftron believes all other animals are irrelevant when compared to the glorious majesty of the giraffe.\nDaniel: Hello, Girafatron!\nGirafatron:",
for seq in sequences:
    print(f"Result: {seq['generated_text']}")

Training Details

Falcon-180B-Chat is based on Falcon-180B.

Training Data

Falcon-180B-Chat is finetuned on a mixture of Ultrachat, Platypus and Airoboros.

The data was tokenized with the Falcon tokenizer.


Paper coming soon.

See the OpenLLM Leaderboard for early results.

Technical Specifications

Model Architecture and Objective

Falcon-180B-Chat is a causal decoder-only model trained on a causal language modeling task (i.e., predict the next token).

The architecture is broadly adapted from the GPT-3 paper (Brown et al., 2020), with the following differences:

For multiquery, we are using an internal variant which uses independent key and values per tensor parallel degree.

Hyperparameter Value Comment
Layers 80
d_model 14848
head_dim 64 Reduced to optimise for FlashAttention
Vocabulary 65024
Sequence length 2048

Compute Infrastructure


Falcon-180B-Chat was trained on AWS SageMaker, on up to 4,096 A100 40GB GPUs in P4d instances.


Falcon-180B-Chat was trained a custom distributed training codebase, Gigatron. It uses a 3D parallelism approach combined with ZeRO and high-performance Triton kernels (FlashAttention, etc.)
