## 🚀 Quick Start

### Using PEFT (Recommended)

```python
from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load base model and tokenizer
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-Coder-1.5B-Instruct",
    device_map="auto",
    torch_dtype=torch.float16,
    trust_remote_code=True
)

tokenizer = AutoTokenizer.from_pretrained(
    "Qwen/Qwen2.5-Coder-1.5B-Instruct",
    trust_remote_code=True
)

# Load LoRA adapter
model = PeftModel.from_pretrained(
    base_model, 
    "amkyawdev/Myanmar-Ghost-Instruct-LoRA"
)

# Generate text
messages = [
    {"role": "user", "content": "မြန်မာစာတစ်ပိုဒ် ရေးပါ။"}
]
text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer([text], return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=512,
    temperature=0.7,
    top_p=0.9
)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

### Using Transformers Pipeline

```python
from transformers import pipeline

pipe = pipeline(
    "text-generation",
    model="amkyawdev/Myanmar-Ghost-Instruct-LoRA",
    model_kwargs={"device_map": "auto", "torch_dtype": "float16"}
)

messages = [
    {"role": "user", "content": "မြန်မာစာတစ်ပိုဒ် ရေးပါ။"}
]
output = pipe(messages, max_new_tokens=512, temperature=0.7)
print(output[0]["generated_text"])
```

### Using vLLM

```bash
# Install vLLM
pip install vllm

# Start server
vllm serve "amkyawdev/Myanmar-Ghost-Instruct-LoRA" --dtype float16

# API call
curl -X POST "http://localhost:8000/v1/chat/completions" \
  -H "Content-Type: application/json" \
  --data '{
    "model": "amkyawdev/Myanmar-Ghost-Instruct-LoRA",
    "messages": [{"role": "user", "content": "မြန်မာစာတစ်ပိုဒ် ရေးပါ။"}]
  }'
```

## 🎯 Intended Uses

### Direct Use Cases
- ✅ Myanmar language text generation
- ✅ Burmese language conversation
- ✅ Translation assistance (Myanmar ↔ other languages)
- ✅ Text summarization in Burmese
- ✅ Code generation assistance (preserved from base model)

### Downstream Use Cases
- 🔧 Fine-tuning for specific Myanmar NLP tasks
- 🔧 Domain-specific applications (healthcare, legal, education)
- 🔧 Chatbot development for Burmese speakers
- 🔧 Research on low-resource language LLMs

### Out-of-Scope Uses
- ⚠️ Medical or legal advice without human verification
- ⚠️ High-stakes decision-making systems
- ⚠️ Production systems without thorough evaluation
- ⚠️ Generating harmful or misleading content

## ⚠️ Bias, Risks, and Limitations

### Technical Limitations
1. **Model Size**: 1.5B parameters may limit performance on complex tasks
2. **Training Steps**: Limited training (200 steps) may affect instruction-following quality
3. **Token Limit**: 32,768 context window
4. **Resource Requirements**: GPU recommended for inference

### Sociotechnical Considerations
1. **Language Coverage**: Optimized primarily for Burmese; may vary for regional dialects
2. **Cultural Bias**: Training data may reflect specific cultural perspectives
3. **Safety**: As with any LLM, outputs should be verified before critical use

### Recommendations
- Evaluate on your specific use case before production deployment
- Implement appropriate content filtering
- Provide human oversight for sensitive applications
- Consider fine-tuning for domain-specific tasks
