## Spotlights

* A bilingual model (English and Chinese) specially enhanced for open-domain NLU.
* Trained with diverse synthesized data and high-quality NLU dataset.
* Handle all NLU tasks that can be transformed into a combination of atomic tasks, classification and extraction.

## 📰  Update News

`SeqGPT` is continuously updating. We have provided online demos for everyone. In the future, we will provide new versions of models with upgraded capabilities. Please continue to pay attention!

- **[2023/10/09]** 💪 We provide [API](https://help.aliyun.com/zh/dashscope/developer-reference/opennlu-api-details) of SeqGPT-3B for users who want to access **larger** SeqGPT.
- **[2023/09/20]** 🎛️ We provide a sample script for fine-tuning on a custom dataset at [here](https://github.com/modelscope/swift/blob/main/examples/pytorch/llm/scripts/seqgpt_560m/full/sft.sh).
- **[2023/08/23]** 🛠️ We release the weight of SeqGPT-560M at both [Modelscope](https://www.modelscope.cn/models/damo/nlp_seqgpt-560m) and [Hugging Face](https://huggingface.co/DAMO-NLP/SeqGPT-560M). You can download and inference with our model simply following the [usage case](#inference).
- **[2023/08/23]** 🔥 We provide an online demo of SeqGPT at [Modelscope](https://www.modelscope.cn/studios/TTCoding/open_ner/summary)! Try it now!
- **[2023/08/21]** 📑 We release the paper of SeqGPT: [SeqGPT: An Out-of-the-box Large Language Model for Open Domain Sequence Understanding](https://arxiv.org/abs/2308.10529). More implementation details and experimental results are presented in the paper.

## Performance

We perform a human evaluation on SeqGPT-7B1 and ChatGPT using the held-out datasets. Ten annotators are tasked to decide which model gives the better answer or two models are tied with each other. SeqGPT-7B1 outperforms ChatGPT on 7/10 NLU tasks but lags behind in sentiment analysis (SA), slot filling (SF) and natural language inference (NLI).

## Usage

### Install

```sh
conda create -n seqgpt python==3.8.16

conda activate seqgpt
pip install -r requirements.txt
```

### Inference

```python
from transformers import AutoTokenizer, AutoModelForCausalLM, AutoModel
import torch

model_name_or_path = 'DAMO-NLP/SeqGPT-560M'
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path)
model = AutoModelForCausalLM.from_pretrained(model_name_or_path)
tokenizer.padding_side = 'left'
tokenizer.truncation_side = 'left'

if torch.cuda.is_available():
    model = model.half().cuda()
model.eval()
GEN_TOK = '[GEN]'

while True:
    sent = input('输入/Input: ').strip()
    task = input('分类/classify press 1, 抽取/extract press 2: ').strip()
    labels = input('标签集/Label-Set (e.g, labelA,LabelB,LabelC): ').strip().replace(',', '，')
    task = '分类' if task == '1' else '抽取'

# Changing the instruction can harm the performance
    p = '输入: {}\n{}: {}\n输出: {}'.format(sent, task, labels, GEN_TOK)
    input_ids = tokenizer(p, return_tensors="pt", padding=True, truncation=True, max_length=1024)
    input_ids = input_ids.to(model.device)
    outputs = model.generate(**input_ids, num_beams=4, do_sample=False, max_new_tokens=256)
    input_ids = input_ids.get('input_ids', input_ids)
    outputs = outputs[0][len(input_ids[0]):]
    response = tokenizer.decode(outputs, skip_special_tokens=True)
    print('BOT: ========== \n{}'.format(response))
```
