gpt2 quantized to 4-bit using AutoGPTQ.
To use, first install AutoGPTQ:
pip install auto-gptq
Then load the model from the hub:
from transformers import AutoModelForCausalLM, AutoTokenizer
from auto_gptq import AutoGPTQForCausalLM, BaseQuantizeConfig
model_name = "smpanaro/gpt2-AutoGPTQ-4bit-128g"
model = AutoGPTQForCausalLM.from_quantized(model_name)
| Model | 4-Bit Perplexity | 16-Bit Perplexity | Delta |
|---|---|---|---|
| smpanaro/gpt2-AutoGPTQ-4bit-128g | 26.5000 | 25.1875 | 1.3125 |
| smpanaro/gpt2-medium-AutoGPTQ-4bit-128g | 19.1719 | 18.4739 | 0.698 |
| smpanaro/gpt2-large-AutoGPTQ-4bit-128g | 16.6875 | 16.4541 | 0.2334 |
| smpanaro/gpt2-xl-AutoGPTQ-4bit-128g | 14.9297 | 14.7951 | 0.1346 |
| Wikitext perplexity measured as in the huggingface docs, lower is better |
