## How to Use

### Installation

```bash
pip install transformers torch accelerate
```

### Basic Usage

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

# Load model and tokenizer
model_name = "Daemontatox/Mini-Hydra"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,

    trust_remote_code=True
)

# Example inference
def generate_response(prompt, max_length=512):
    inputs = tokenizer.encode(prompt, return_tensors="pt")
    
    with torch.no_grad():
        outputs = model.generate(
            inputs,
            max_length=max_length,

    response = tokenizer.decode(outputs[0], skip_special_tokens=True)
    return response[len(prompt):].strip()

# Example usage
prompt = "Solve this step by step: If a train travels 120 miles in 2 hours, and then 180 miles in 3 hours, what is the average speed for the entire journey?"
response = generate_response(prompt)
print(response)
```

### Advanced Usage with Custom Parameters

```python
from transformers import AutoTokenizer, AutoModelForCausalLM, GenerationConfig
import torch

model_name = "Daemontatox/Mini-Hydra"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto",

A rectangular garden has a length that is 3 times its width. 
If the perimeter is 32 meters, what are the dimensions of the garden?
"""

solution = reasoning_generate(math_problem)
print(solution)
```

### Batch Processing

```python
def batch_reasoning(prompts, batch_size=4):
    results = []
    
    for i in range(0, len(prompts), batch_size):
        batch_prompts = prompts[i:i+batch_size]
        batch_inputs = tokenizer(
            batch_prompts, 
            return_tensors="pt", 
            padding=True, 
            truncation=True
        )
        
        with torch.no_grad():
            batch_outputs = model.generate(
                **batch_inputs,
                max_length=512,
                temperature=0.7,
                do_sample=True,
                pad_token_id=tokenizer.eos_token_id
            )
        
        batch_responses = tokenizer.batch_decode(batch_outputs, skip_special_tokens=True)
        results.extend(batch_responses)
    
    return results

# Example batch processing
problems = [
    "What is 15% of 240?",
    "If x + 5 = 12, what is x?",
    "A circle has radius 7. What is its area?",
    "Solve: 2x + 3 = 15"
]

solutions = batch_reasoning(problems)
for problem, solution in zip(problems, solutions):
    print(f"Problem: {problem}")
    print(f"Solution: {solution}")
    print("-" * 50)
```

## Example Outputs

### Mathematical Reasoning

```python
Input: "Solve this step by step: If a train travels 120 miles in 2 hours, and then 180 miles in 3 hours, what is the average speed for the entire journey?"

Output: "Let me solve this step by step:

Step 1: Calculate total distance
Total distance = 120 miles + 180 miles = 300 miles

Step 2: Calculate total time
Total time = 2 hours + 3 hours = 5 hours

Step 3: Calculate average speed
Average speed = Total distance ÷ Total time
Average speed = 300 miles ÷ 5 hours = 60 miles per hour

Therefore, the average speed for the entire journey is 60 mph."
```

### Logical Reasoning

```python
Input: "If all roses are flowers, and some flowers are red, can we conclude that some roses are red?"

Output: "Let me analyze this logical statement:

Given premises:
1. All roses are flowers
2. Some flowers are red

The question asks if we can conclude that some roses are red.

Analysis:
- From premise 1: roses ⊆ flowers (roses are a subset of flowers)
- From premise 2: ∃ flowers that are red

However, we cannot definitively conclude that some roses are red because:
- The red flowers mentioned in premise 2 might be flowers other than roses
- We have no information directly connecting roses to the property of being red

Conclusion: No, we cannot logically conclude that some roses are red based solely on the given premises."
```

### Code Generation with Reasoning

```python
Input: "Write a Python function to find the factorial of a number, and explain your approach."

Output: "Here's a Python function to calculate factorial with explanation:


def factorial(n):
    """
    Calculate the factorial of a non-negative integer n.
    
    Args:
        n (int): Non-negative integer
        
    Returns:
        int: n! (factorial of n)
        
    Raises:
        ValueError: If n is negative
    """
    if n < 0:
        raise ValueError("Factorial is not defined for negative numbers")
    elif n == 0 or n == 1:
        return 1
    else:
        result = 1
        for i in range(2, n + 1):
            result *= i
        return result
```

## Reasoning behind the approach:
1. Input validation: Check for negative numbers since factorial is undefined for them
2. Base cases: 0! = 1 and 1! = 1 by mathematical definition
3. Iterative calculation: For n > 1, multiply all integers from 2 to n
4. This iterative approach is more memory-efficient than recursion for large numbers

## Example usage:
```python
print(factorial(5))  # Output: 120
print(factorial(0))  # Output: 1
```
