# Model Card for Model ID

This is an adapter prepared to return True or False depending on whether the student's answer ("student_answer") is correct based on the question ("question") and comparing it with a given answer ("best_answer").
The prompt has the following structure:
```
<start_of_turn>user\n
Analyze the question, the expected answer, and the student's response. Determine if the student's answer is conceptually correct in relation to the expected answer, regardless of the exact wording. An answer will be considered correct if it accurately identifies the key information requested in the question, even if expressed differently. Return True if the student's answer is correct or False otherwise. Add a brief comment explaining the rationale behind the answer being correct or incorrect.

Question: {question}
Expected Answer: {best_answer}
Student Answer: {student_answer}<end_of_turn>\n

```


## How to Get Started with the Model
In Google Colab:
```

!pip install -q -U bitsandbytes
!pip install -q -U git+https://github.com/huggingface/transformers.git
!pip install -q -U git+https://github.com/huggingface/peft.git
!pip install -q -U git+https://github.com/huggingface/accelerate.git
!pip install -q -U gradio
