🔍 [Model on Hugging Face](https://huggingface.co/MatteoKhan/CodeLlama-Hybrid-7B)  

## 🧠 Model Details
- **Model Type**: Hybrid Language Model (Merged for Code Generation)
- **Parent Models**:
  - [CodeLlama-7B](https://huggingface.co/codellama/CodeLlama-7b-hf)
  - [CodeLlama-7B-Python](https://huggingface.co/codellama/CodeLlama-7b-Python-hf)
- **Merging Technique**: Linear Merge (MergeKit)
- **Tokenizer Source**: `codellama/CodeLlama-7b-hf`

## 🎯 Intended Use
This model is designed for **code-related tasks** and experimentation in hybrid model optimization. Possible applications include:
- ✅ Code Generation
- ✅ Code Completion & Assistance
- ✅ Code Understanding & Refactoring
- ✅ Exploration of Model Merging Effects on Programming Tasks

## ⚠️ Limitations & Considerations
While **CodeLlama-Hybrid-7B** provides enhanced code generation capabilities, it inherits some limitations from its parent models:
- ❌ May produce **incorrect or insecure** code
- ⚠️ Can generate **biased, offensive, or inappropriate** content
- 🔄 Merging may introduce **unpredictable behaviors**
- 📉 Performance may **vary depending on the programming language and context**

## 🔬 Merging Process & Configuration
This is **not a newly trained model**, but rather a merge of existing models using the following configuration:

```yaml
merge_method: linear
dtype: float16
allow_crimes: true
models:
  - model: "codellama/CodeLlama-7b-hf"
    parameters:
      t: 1.0
      weight: 0.5
  - model: "codellama/CodeLlama-7b-Python-hf"
    parameters:
      t: 1.0
      weight: 0.5
parameters:
  normalize: true
  int8_mask: false
  ignore_mismatched_sizes: true
layers:
  - pattern: "model.*"
tokenizer_source: "codellama/CodeLlama-7b-hf"
```

📊 **No formal evaluation** has been conducted yet. Users are encouraged to **benchmark and share feedback**!

## 🌍 Environmental Impact
By utilizing **model merging** instead of training from scratch, **CodeLlama-Hybrid-7B** significantly reduces computational and environmental costs.

## 🚀 How to Use
```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "MatteoKhan/CodeLlama-Hybrid-7B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name)

# Example usage
prompt = "Write a Python function to calculate Fibonacci numbers."
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=200)
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
```
