OpenHathi Base GPTQ

Description

This repo contains GPTQ model files for Sarvam's OpenHathi.

Files are made using AutoGPTQ with following config. 

quantization_config : {"bits": 4,
  "group_size": 128,
  "damp_percent": 0.1,
  "desc_act": true,

}

We use a custom dataset which has both Hindi and English wiki articles. We truncate to max_length=1024 and model may not perform well beyond that context size.

Prompt template

This is a base model not tuned for any instructions. Feel free to use any format. Alpaca/Vicuna works fine.

Oobagooba

Standard oobagooba works with exllama2 / autogptq loader

Using in code 

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

model_name_or_path = "cmeraki/OpenHathi-7B-Hi-v0.1-Base-gptq"
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)
