# Model Card for mEdIT-xl

The `medit-xl` model was obtained by fine-tuning the `MBZUAI/bactrian-x-llama-7b-lora` model on the mEdIT dataset.

**Authors:** Vipul Raheja, Dimitris Alikaniotis, Vivek Kulkarni, Bashar Alhafni, Dhruv Kumar

## Model Details

### Model Description

- **Language(s) (NLP)**: Arabic, Chinese, English, German, Japanese, Korean, Spanish
- **Finetuned from model:** `MBZUAI/bactrian-x-llama-7b-lora`

### Model Sources

- **Repository:** https://github.com/vipulraheja/medit

## How to use

Given an edit instruction and an original text, our model can generate the edited version of the text.<br>

![task_specs](https://cdn-uploads.huggingface.co/production/uploads/60985a0547dc3dbf8a976607/816ZY2t0XPCpMMd6Z072K.png)

Specifically, our models support both multi-lingual and cross-lingual text revision. Note that the input and output texts are always in the same language. The monolingual
vs. cross-lingual setting is determined by comparing the language of the edit instruction in relation to the language of the input text.

### Instruction format

Adherence to the following instruction format is essential; failure to do so may result in the model producing less-than-ideal results.

```
instruction_tokens = [
    "Instruction",
    "Anweisung",
    ...
]

input_tokens = [
    "Input",
    "Aporte",
    ...
]

output_tokens = [
    "Output",
    "Produzione",
    ...
]

task_descriptions = [
    "Fix grammatical errors in this sentence",  # <-- GEC task
    "Umschreiben Sie den Satz",                 # <-- Paraphrasing
    ...
]
```

**The entire list of possible instructions, input/output tokens, and task descriptions can be found in the Appendix of our paper.**

```
prompt_template = """### <instruction_token>:\n<task_description>\n### <input_token>:\n<input>\n### <output_token>:\n\n"""
```

Note that the tokens and the task description need not be in the language of the input (in the case of cross-lingual revision).


### Run the model

```python
from transformers import AutoTokenizer, AutoModelForCausalLM

model_id = "grammarly/medit-xl"
tokenizer = AutoTokenizer.from_pretrained(model_id)

model = AutoModelForCausalLM.from_pretrained(model_id)

# English GEC using Japanese instructions
prompt = '### 命令:\n文章を文法的にする\n### 入力:\nI has small cat ,\n### 出力:\n\n'

inputs = tokenizer(prompt, return_tensors='pt')

outputs = model.generate(**inputs, max_new_tokens=20)

print(tokenizer.decode(outputs[0], skip_special_tokens=True)

# --> I have a small cat ,

# German GEC using Japanese instructions
prompt = '### 命令:\n文章を文法的にする\n### 入力:\nIch haben eines kleines Katze ,\n### 出力:\n\n'

# ...
# --> Ich habe eine kleine Katze ,
```
