OpenGPT 7B Instruct v1.0
- Model creator: Achyuth Gamer
- Original model: OpenGPT
Description
This repo contains GPTQ model files for Achyuth AI's OpenGPT 7B v1.0.
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.
GPTQs will work in ExLlama, or via Transformers (requiring Transformers from Github)
These models are confirmed to work with ExLlama v1.
At the time of writing (September 28th), AutoGPTQ has not yet added support for the new OpenGPT models.
These GPTQs were made directly from Transformers, and so can be loaded via the Transformers interface. They can't be loaded directly from AutoGPTQ.
To load them via Transformers, you will need to install Transformers from Github, with:
pip3 install git+https://github.com/huggingface/transformers.git@72958fcd3c98a7afdc61f953aa58c544ebda2f79
Repositories available
- AWQ model(s) for GPU inference.
- GPTQ models for GPU inference, with multiple quantisation parameter options.
- OpenGPT AI's original unquantised fp16 model in pytorch format, for GPU inference and for further conversions
Prompt template: OpenGPT
<s>[INST] {prompt} [/INST]
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.
These files were made with Transformers 4.34.0.dev0, from commit 72958fcd3c98a7afdc61f953aa58c544ebda2f79.
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 calibration dataset used during quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ calibration 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 | 32768 | 4.16 GB | Yes | 4-bit, with Act Order and group size 128g. Uses even less VRAM than 64g, but with slightly lower accuracy. |
gptq-4bit-32g-actorder_True | 4 | 32 | Yes | 0.1 | wikitext | 32768 | 4.57 GB | Yes | 4-bit, with Act Order and group size 32g. Gives highest possible inference quality, with maximum VRAM usage. |
gptq-8bit-128g-actorder_True | 8 | 128 | Yes | 0.1 | wikitext | 32768 | 7.68 GB | Yes | 8-bit, with group size 128g for higher inference quality and with Act Order for even higher accuracy. |
gptq-8bit-32g-actorder_True | 8 | 32 | Yes | 0.1 | wikitext | 32768 | 8.17 GB | Yes | 8-bit, with group size 32g and Act Order for maximum inference quality. |
How to download, including from branches
In text-generation-webui
To download from the main
branch, enter AchyuthGamer/OpenGPT-7b-0.1
in the "Download model" box.
To download from another branch, add :branchname
to the end of the download name, eg AchyuthGamer/OpenGPT-7b-0.1:gptq-4bit-32g-actorder_True
From the command line
I recommend using the huggingface-hub
Python library:
pip3 install huggingface-hub
To download the main
branch to a folder called OpenGPT-7B-Instruct-v1.0-GPTQ
:
mkdir OpenGPT-7b-0.1
huggingface-cli download AchyuthGamer/OpenGPT-7b-0.1 --local-dir OpenGPT-7b-0.1 --local-dir-use-symlinks False
To download from a different branch, add the --revision
parameter:
mkdir OpenGPT-7B-Instruct-v1.0-GPTQ
huggingface-cli download AchyuthGamer/OpenGPT-7b-0.1 --revision gptq-4bit-32g-actorder_True --local-dir OpenGPT-7b-0.1 --local-dir-use-symlinks False
More advanced huggingface-cli download usage
If you remove the --local-dir-use-symlinks False
parameter, the files will instead be stored in the central Huggingface cache directory (default location on Linux is: ~/.cache/huggingface
), and symlinks will be added to the specified --local-dir
, pointing to their real location in the cache. This allows for interrupted downloads to be resumed, and allows you to quickly clone the repo to multiple places on disk without triggering a download again. The downside, and the reason why I don't list that as the default option, is that the files are then hidden away in a cache folder and it's harder to know where your disk space is being used, and to clear it up if/when you want to remove a download model.
The cache location can be changed with the HF_HOME
environment variable, and/or the --cache-dir
parameter to huggingface-cli
.
For more documentation on downloading with huggingface-cli
, please see: HF -> Hub Python Library -> Download files -> Download from the CLI.
To accelerate downloads on fast connections (1Gbit/s or higher), install hf_transfer
:
pip3 install hf_transfer
And set environment variable HF_HUB_ENABLE_HF_TRANSFER
to 1
:
mkdir OpenGPT-7b-0.1
HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download AchyuthGamer/OpenGPT-7b-0.1 --local-dir OpenGPT-7b-0.1 --local-dir-use-symlinks False
Windows Command Line users: You can set the environment variable by running set HF_HUB_ENABLE_HF_TRANSFER=1
before the download command.
With git
(not recommended)
To clone a specific branch with git
, use a command like this:
git clone --single-branch --branch gptq-4bit-32g-actorder_True https://huggingface.co/AchyuthGamer/OpenGPT-7b-0.1
Note that using Git with HF repos is strongly discouraged. It will be much slower than using huggingface-hub
, and will use twice as much disk space as it has to store the model files twice (it stores every byte both in the intended target folder, and again in the .git
folder as a blob.)
How to easily download and use this model in text-generation-webui.
These models are confirmed to work via the ExLlama Loader in text-generation-webui.
Use Loader: ExLlama - or Transformers may work too. AutoGPTQ will not work.
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.

git checkout v0.4.2
pip3 install .
You can then use the following code
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
model_name_or_path = "AchyuthGamer/OpenGPT-7B-v1.0"
# To use a different branch, change revision
# For example: revision="gptq-4bit-32g-actorder_True"
model = AutoModelForCausalLM.from_pretrained(model_name_or_path,
device_map="auto",
trust_remote_code=False,
revision="main")
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, use_fast=True)
prompt = "Tell me about AI"
prompt_template=f'''<s>[INST] {prompt} [/INST]
'''
print("\n\n*** Generate:")
input_ids = tokenizer(prompt_template, return_tensors='pt').input_ids.cuda()
output = model.generate(inputs=input_ids, temperature=0.7, do_sample=True, top_p=0.95, top_k=40, max_new_tokens=512)
print(tokenizer.decode(output[0]))
# Inference can also be done using transformers' pipeline

Original model card: OpenGPT AI's OpenGPT 7B Instruct v1.0
Model Card for OpenGPT-7B-v1.0
The OpenGPT-7B-Instruct-v1.0 Large Language Model (LLM) is a instruct fine-tuned version of the OpenGPT-7B-v1.0 generative text model using a variety of publicly available conversation datasets.
For full details of this model please read our release blog post
Instruction format
In order to leverage instruction fine-tuning, your prompt should be surrounded by [INST]
and [\INST]
tokens. The very first instruction should begin with a begin of sentence id. The next instructions should not. The assistant generation will be ended by the end-of-sentence token id.
E.g.
text = "<s>[INST] What is your favourite condiment? [/INST]"
"Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!</s> "
"[INST] Do you have mayonnaise recipes? [/INST]"
This format is available as a chat template via the apply_chat_template()
method:
from transformers import AutoModelForCausalLM, AutoTokenizer
device = "cuda" # the device to load the model onto
model = AutoModelForCausalLM.from_pretrained("OpenGPTai/OpenGPT-7B-Instruct-v1.0")
tokenizer = AutoTokenizer.from_pretrained("OpenGPTai/OpenGPT-7B-Instruct-v1.0")
messages = [
{"role": "user", "content": "What is your favourite condiment?"},
{"role": "assistant", "content": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"},
{"role": "user", "content": "Do you have mayonnaise recipes?"}
]
encodeds = tokenizer.apply_chat_template(messages, return_tensors="pt")
model_inputs = encodeds.to(device)
model.to(device)
generated_ids = model.generate(model_inputs, max_new_tokens=1000, do_sample=True)
decoded = tokenizer.batch_decode(generated_ids)
print(decoded[0])
Model Architecture
This instruction model is based on OpenGPT-7B-v1.0, a transformer model with the following architecture choices:
- Grouped-Query Attention
- Sliding-Window Attention
- Byte-fallback BPE tokenizer
Troubleshooting
- If you see the following error:
Traceback (most recent call last):
File "", line 1, in
File "/transformers/models/auto/auto_factory.py", line 482, in from_pretrained
config, kwargs = AutoConfig.from_pretrained(
File "/transformers/models/auto/configuration_auto.py", line 1022, in from_pretrained
config_class = CONFIG_MAPPING[config_dict["model_type"]]
File "/transformers/models/auto/configuration_auto.py", line 723, in getitem
raise KeyError(key)
KeyError: 'OpenGPT'
Installing transformers from source should solve the issue pip install git+https://github.com/huggingface/transformers
This should not be required after transformers-v4.33.4.
Limitations
The OpenGPT 7B Instruct model is a quick demonstration that the base model can be easily fine-tuned to achieve compelling performance. It does not have any moderation mechanisms. We're looking forward to engaging with the community on ways to make the model finely respect guardrails, allowing for deployment in environments requiring moderated outputs.
