## 🚀 Usage
### Quick Start
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch
# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
"Qwen/Qwen2.5-Coder-32B-Instruct",
dtype=torch.bfloat16,
device_map="auto"
)
# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-Coder-32B-Instruct")
# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "juspay/Qwen2.5-Coder-32B-Instruct-CPT-LoRA-Adapter-HyperSwitch")
# Generate code
prompt = """// Hyperswitch payment processing
pub fn validate_payment_method("""
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
**inputs,
max_new_tokens=200,
temperature=0.2, # Lower temperature for code generation
do_sample=True,
pad_token_id=tokenizer.eos_token_id
)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
### Recommended Settings
- **Temperature**: 0.2-0.3 for code generation
- **Temperature**: 0.5-0.7 for explanations and documentation
- **Max tokens**: 512-1024 for most tasks
## 🛠️ Technical Specifications
- **Context Window**: 8,192 tokens
- **Precision**: bfloat16
