rinna/youri-7b-chat-gptq

Overview

rinna/youri-7b-chat-gptq is the quantized model for rinna/youri-7b-chat using AutoGPTQ. The quantized version is 4x smaller than the original model and thus requires less memory and provides faster inference.

• Model architecture

  Refer to the original model for architecture details.

• Fine-tuning

  Refer to the original model for fine-tuning details.

Benchmarking

Our evaluation experiments show that the quantization yields slight performance degradation on downstream tasks.

Results will be updated soon.

How to use the model

import torch
from transformers import AutoTokenizer
from auto_gptq import AutoGPTQForCausalLM

tokenizer = AutoTokenizer.from_pretrained("rinna/youri-7b-chat-gptq")
model = AutoGPTQForCausalLM.from_quantized("rinna/youri-7b-chat-gptq", use_safetensors=True)

instruction = "次の日本語を英語に翻訳してください。"
input = "自然言語による指示に基づきタスクが解けるよう学習させることを Instruction tuning と呼びます。"

        "text": instruction
    },

    }

    for uttr in context

        eos_token_id=tokenizer.eos_token_id
    )

output = tokenizer.decode(output_ids.tolist()[0])
print(output)

Tokenization

The model uses the original llama-2 tokenizer.
