Eric Hartford's Samantha 33B GPTQ
These files are GPTQ 4bit model files for Eric Hartford's Samantha 33B merged with Kaio Ken's SuperHOT 8K.
It is the result of quantising to 4bit using GPTQ-for-LLaMa.
This is an experimental new GPTQ which offers up to 8K context size
The increased context is tested to work with ExLlama, via the latest release of text-generation-webui.
It has also been tested from Python code using AutoGPTQ, and trust_remote_code=True
.
Code credits:
- Original concept and code for increasing context length: kaiokendev
- Updated Llama modelling code that includes this automatically via trust_remote_code: emozilla.
Please read carefully below to see how to use it.
NOTE: Using the full 8K context on a 30B model will exceed 24GB VRAM.
GGML versions are not yet provided, as there is not yet support for SuperHOT in llama.cpp. This is being investigated and will hopefully come soon.
Repositories available
- 4-bit GPTQ models for GPU inference
- Unquantised SuperHOT fp16 model in pytorch format, for GPU inference and for further conversions
- Unquantised base fp16 model in pytorch format, for GPU inference and for further conversions
How to easily download and use this model in text-generation-webui with ExLlama
Please make sure you're using the latest version of text-generation-webui
- Click the Model tab.
- Under Download custom model or LoRA, enter
TheBloke/Samantha-33B-SuperHOT-8K-GPTQ
. - Click Download.
- The model will start downloading. Once it's finished it will say "Done"
- Untick Autoload the model
- In the top left, click the refresh icon next to Model.
- In the Model dropdown, choose the model you just downloaded:
Samantha-33B-SuperHOT-8K-GPTQ
- To use the increased context, set the Loader to ExLlama, set max_seq_len to 8192 or 4096, and set compress_pos_emb to 4 for 8192 context, or to 2 for 4096 context.
- Now click Save Settings followed by Reload
- The model will automatically load, and is now ready for use!
- 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 with AutoGPTQ
First make sure you have AutoGPTQ and Einops installed:
pip3 install einops auto-gptq
Then run the following code. Note that in order to get this to work, config.json
has been hardcoded to a sequence length of 8192.
If you want to try 4096 instead to reduce VRAM usage, please manually edit config.json
to set max_position_embeddings
to the value you want.

from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig

output = model.generate(inputs=input_ids, temperature=0.7, max_new_tokens=512)
print(tokenizer.decode(output[0]))
# Inference can also be done using transformers' pipeline
# Prevent printing spurious transformers error when using pipeline with AutoGPTQ
logging.set_verbosity(logging.CRITICAL)

Using other UIs: monkey patch
Provided in the repo is llama_rope_scaled_monkey_patch.py
, written by @kaiokendev.
It can be theoretically be added to any Python UI or custom code to enable the same result as trust_remote_code=True
. I have not tested this, and it should be superseded by using trust_remote_code=True
, but I include it for completeness and for interest.
Provided files
samantha-33b-superhot-8k-GPTQ-4bit-128g.no-act.order.safetensors
This will work with AutoGPTQ, ExLlama, and CUDA versions of GPTQ-for-LLaMa. There are reports of issues with Triton mode of recent GPTQ-for-LLaMa. If you have issues, please use AutoGPTQ instead.
It was created with group_size 128 to increase inference accuracy, but without --act-order (desc_act) to increase compatibility and improve inference speed.
samantha-33b-superhot-8k-GPTQ-4bit-128g.no-act.order.safetensors
- Works for use with ExLlama with increased context (4096 or 8192)
- Works with AutoGPTQ in Python code, including with increased context, if
trust_remote_code=True
is set. - Should work with GPTQ-for-LLaMa in CUDA mode, but unknown if increased context works - TBC. May have issues with GPTQ-for-LLaMa Triton mode.
- Works with text-generation-webui, including one-click-installers.
- Parameters: Groupsize = 128. Act Order / desc_act = False.

Thanks, and how to contribute.
Thanks to the chirper.ai team!
I've had a lot of people ask if they can contribute. I enjoy providing models and helping people, and would love to be able to spend even more time doing it, as well as expanding into new projects like fine tuning/training.
If you're able and willing to contribute it will be most gratefully received and will help me to keep providing more models, and to start work on new AI projects.
Donaters will get priority support on any and all AI/LLM/model questions and requests, access to a private Discord room, plus other benefits.

SuperHOT Prototype 2 w/ 8K Context
This is a second prototype of SuperHOT, this time 30B with 8K context and no RLHF, using the same technique described in the github blog. Tests have shown that the model does indeed leverage the extended context at 8K.
You will need to use either the monkeypatch or, if you are already using the monkeypatch, change the scaling factor to 0.25 and the maximum sequence length to 8192
