mGPT-quantized
The concept: 8-bit quantized version of mGPT-13B, an LLM released by AI-Forever / Sberbank AI in 2022-2023.
On the GPT scale, it is a similar # of parameters to GPT-3, but trained on 60+ languages.
My goal is to evaluate this on Hindi and Indonesian tasks, where there are fewer autoregressive language models in this size range.
For English: use a GPT model or LLaMa2-7B
For Arabic: in August 2023 I would recommend the bilingual JAIS model, which is also 13B parameters can be quantized.
In August 2023 AI-Forever added 1.3B-param models for 20+ languages. If your language is Mongolian, for example, it might be better to use mGPT-1.3B-mongol and not this one.
They also have a 1.3B param model for all languages, which I further quantized here: https://huggingface.co/monsoon-nlp/mGPT-quantized
How was the model created?
Quantization of mGPT-13B was done using bitsandbytes
library, CoLab Pro with an A100 GPU, and a lot of space on Google Drive.
from transformers import BitsAndBytesConfig, GPT2LMHeadModel
quantization_config = BitsAndBytesConfig(
load_in_8bit=True,
bnb_8bit_compute_dtype=torch.bfloat16,
bnb_8bit_use_double_quant=True,
bnb_8bit_quant_type="nf4",
)
qmodel = GPT2LMHeadModel.from_pretrained(
"ai-forever/mGPT-13B",
load_in_8bit=True,
torch_dtype=torch.bfloat16,
quantization_config=quantization_config,
device_map="auto"
)
qmodel.save_pretrained("model_name")
Future steps
- mGPT could be further quantized (4-bit), but
model.save_pretrained()
currently throws aNotImplementedError
error.
