## Model Details

### **Base Model**
[microsoft/phi-2](https://huggingface.co/microsoft/phi-2) (2.7B parameters, MIT License)

### **Training Data**
1. **[UltraChat](https://github.com/thunlp/UltraChat)** (CC-BY-NC-4.0):
```bibtex
   @misc{ultrachat,
     title={UltraChat: A Large-Scale Auto-generated Multi-round Dialogue Dataset},
     author={Ding et al.},
     year={2023},
     howpublished={\url{https://github.com/thunlp/UltraChat}}
   }
```
2. Custom synthetic data(Proprietary)


### **Fine-Tuning**
- **Objective**: Instruction-following & conversational ability
- **Framework**: PyTorch + Transformers
- **Context Window**: 2048 tokens


## Usage

### Quick Inference

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "Irfanuruchi/phi-2-chat",
    trust_remote_code=True,
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("Irfanuruchi/phi-2-chat")

# Recommended prompt format:
input_text = "<|user|>Explain dark matter<|assistant|>"
inputs = tokenizer(input_text, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=200)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

```
