## Usage

### Using with Transformers

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

# Load base model
base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-7B-Instruct",
    torch_dtype="auto",
    device_map="auto"
)

# Load LoRA adapter
model = PeftModel.from_pretrained(
    base_model,
    "FutureMa/Qwen2.5-7B-Instruct-GRPO-Math"
)

tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-7B-Instruct")

# Generate
messages = [
    {"role": "user", "content": "Solve for x: 2x^2 - 3x + 1 = 0"}
]
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)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

### Using with ms-swift

```bash
# Inference
swift infer \
    --ckpt_dir FutureMa/Qwen2.5-7B-Instruct-GRPO-Math \
    --eval_human false
```

## Intended Use

This model is optimized for:
- ✅ Mathematical reasoning and problem-solving
- ✅ Step-by-step solution generation
- ✅ Algebraic equation solving
- ✅ Arithmetic calculations

## Limitations

- Trained on a relatively small dataset (500 samples)
- May not generalize well to very complex mathematical problems
- LoRA fine-tuning may have limited capacity compared to full fine-tuning
