Model Card for Model ID

The model is a fined tuned version of a Korean Large Language model KT-AI/midm-bitext-S-7B-inst-v1.

The purpose of the model is to analyze any "food order sentence" and extract information of product from the sentence.

For example, let's assume an ordering sentence:

여기요 춘천닭갈비 4인분하고요. 라면사리 추가하겠습니다. 콜라 300ml 두캔주세요.

Then the model is expected to generate product informations like:

- 분석 결과 0: 음식명:춘천닭갈비, 수량:4인분
- 분석 결과 1: 음식명:라면사리
- 분석 결과 2: 음식명:콜라, 옵션:300ml, 수량:두캔

Model Details

Model Description

• Developed by: Jangmin Oh
• Model type: a Decoder-only Transformer
• Language(s) (NLP): ko
• License: You should keep the CC-BY-NC 4.0 form KT-AI.

Bias, Risks, and Limitations

The current model was developed using the GPT-4 API to generate a dataset for order sentences, and it has been fine-tuned on this dataset. Please note that we do not assume any responsibility for risks or damages caused by this model.

How to Get Started with the Model

This is a simple example of usage of the model. If you want to load the fined-tuned model in INT4, please specify @load_in_4bit=True@ instead of @load_in_8bit=True@.

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, TextStreamer

model_id = 'jangmin/merged-midm-7B-food-order-understanding-30K'

prompt_template = """###System;{System}
###User;{User}
###Midm;"""

default_system_msg = (
    "너는 먼저 사용자가 입력한 주문 문장을 분석하는 에이전트이다. 이로부터 주문을 구성하는 음식명, 옵션명, 수량을 차례대로 추출해야 한다."
)

def wrapper_generate(model, tokenizer, input_prompt, do_stream=False):
    data = tokenizer(input_prompt, return_tensors="pt")
    streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)
    input_ids = data.input_ids[..., :-1]
    with torch.no_grad():
        pred = model.generate(
            input_ids=input_ids.cuda(),
            streamer=streamer if do_stream else None,

            max_new_tokens=float('inf'),
            do_sample=False
        )
    decoded_text = tokenizer.batch_decode(pred, skip_special_tokens=True)
    decoded_text = decoded_text[0].replace("<[!newline]>", "\n")
    return (decoded_text[len(input_prompt):])

    device_map="auto",,
    trust_remote_code=True,
)

tokenizer = AutoTokenizer.from_pretrained(
    model_id,
    trust_remote_code=True,
)

sentence = "아이스아메리카노 톨사이즈 한잔 하고요. 딸기스무디 한잔 주세요. 또, 콜드브루라떼 하나요."
analysis = wrapper_generate(
    model=trained_model,
    tokenizer=tokenizer,
    input_prompt=prompt_template.format(System=default_system_msg, User=sentence),

Training Details

Training Data

The dataset was generated by GPT-4 API with a carefully designed prompt. A prompt template is desginged to generate examples of sentence pairs of a food order and its understanding. Total 30k examples were generated. Note that it cost about $400 to generate 30K examples through 3,000 API calls.

Some generated examples are as follows:

{
  'input': '다음은 매장에서 고객이 음식을 주문하는 주문 문장이다. 이를 분석하여 음식명, 옵션명, 수량을 추출하여 고객의 의도를 이해하고자 한다.\n분석 결과를 완성해주기 바란다.\n\n### 명령: 제육볶음 한그릇하고요, 비빔밥 한그릇 추가해주세요. ### 응답:\n',
  'output': '- 분석 결과 0: 음식명:제육볶음,수량:한그릇\n- 분석 결과 1: 음식명:비빔밥,수량:한그릇'
},
{
  'input': '다음은 매장에서 고객이 음식을 주문하는 주문 문장이다. 이를 분석하여 음식명, 옵션명, 수량을 추출하여 고객의 의도를 이해하고자 한다.\n분석 결과를 완성해주기 바란다.\n\n### 명령: 사천탕수육 곱배기 주문하고요, 샤워크림치킨도 하나 추가해주세요. ### 응답:\n',
  'output': '- 분석 결과 0: 음식명:사천탕수육,옵션:곱배기\n- 분석 결과 1: 음식명:샤워크림치킨,수량:하나'
}
