[pythia-1b](https://huggingface.co/EleutherAI/pythia-1b) quantized to 4-bit using [AutoGPTQ](https://github.com/AutoGPTQ/AutoGPTQ).

To use, first install AutoGPTQ:

```shell
pip install auto-gptq
```

Then load the model from the hub:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig

model_name = "smpanaro/pythia-1b-AutoGPTQ-4bit-128g"
model = AutoGPTQForCausalLM.from_quantized(model_name)
```
