# Model Card for Model ID

<!-- Provide a quick summary of what the model is/does. -->

Cesterqwen is a fine-tuned Qwen2.5-1.5B model that is able to generate Libcester unit test cases in the correct format.

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->

<!-- This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated. -->

- **Developed by:** Xavier Woon
<!-- - **Funded by [optional]:** [More Information Needed]
- **Shared by [optional]:** [More Information Needed] -->
- **Model type:** Qwen
<!-- - **Language(s) (NLP):** [More Information Needed]
- **License:** [More Information Needed] -->
- **Finetuned from model [optional]:** Qwen/Qwen2.5-1.5B-Instruct

<!-- ### Model Sources [optional]

Provide the basic links for the model.

- **Repository:** [More Information Needed]
- **Paper [optional]:** [More Information Needed]
- **Demo [optional]:** [More Information Needed] -->

<!-- ## Uses -->

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

<!-- ### Direct Use -->

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->

<!-- [More Information Needed] -->

<!-- ### Downstream Use [optional] -->

<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->

<!-- [More Information Needed] -->

<!-- ### Out-of-Scope Use -->

<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->

<!-- [More Information Needed] -->

## Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->

The model often regenerates the input prompt in the output. This can lead to limited test cases being printed due to truncations based on `max_new_tokens`.

### Recommendations

<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->

Expanding the dataset will help increase the accuracy and robustness of the model, and improve code coverage based on real life scenarios.

## How to Get Started with the Model

Use the code below to get started with the model.

```py
from transformers import AutoModelForCausalLM, Qwen2Tokenizer

model_name = "xavierwoon/cesterqwen"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = Qwen2Tokenizer.from_pretrained(model_name)

# Paste your own code inside
code = """
void add()
{
   int a,b,c;
   printf("\nEnter The Two values:");
   scanf("%d%d",&a,&b);
   c=a+b;
   printf("Addition:%d",c);
}
"""

prompt = f"""### Instruction:
create cester test cases for this function:
{code}

### Input:

### Response:
"""

inputs = tokenizer(prompt, return_tensors="pt").to("cpu")

from transformers import TextStreamer
text_streamer = TextStreamer(tokenizer)
_ = model.generate(**inputs, streamer = text_streamer, max_new_tokens = 2048)
```

## Training Details

### Training Data

<!-- This should link to a Dataset Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. -->

Training Data was created based on Data Structures and Algorithm (DSA) codes created using ChatGPT. It would also create corresponding Cester test cases. After testing and ensuring a good code coverage, the prompt and corresponding test cases were added to the dataset.

### Training Procedure

<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. -->

1. Prompt GPT for sample DSA C code
2. Prompt GPT for Libcester unit test cases with 100% code coverage
3. Test generated test cases for robustness and code coverage

<!-- #### Preprocessing [optional]

<!-- #### Training Hyperparameters -->

<!-- - **Training regime:** [More Information Needed] fp32, fp16 mixed precision, bf16 mixed precision, bf16 non-mixed precision, fp16 non-mixed precision, fp8 mixed precision -->

<!-- #### Speeds, Sizes, Times [optional] -->

<!-- This section provides information about throughput, start/end time, checkpoint size if relevant, etc. -->
