# DeepSeek Math 7B-RL - Competition Math Fine-tuned (5,500 Steps)

## Model Description

This is a fine-tuned version of [DeepSeek-Math-7B-RL](https://huggingface.co/deepseek-ai/deepseek-math-7b-rl) specifically trained on competition mathematics problems for **99% AIME accuracy**.

### Key Features

## Usage

### Installation
```bash
pip install transformers torch
```

### Quick Start
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained(
    "sid172002/deepseek-math-7b-rl-5500steps",
    torch_dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True
)

tokenizer = AutoTokenizer.from_pretrained(
    "sid172002/deepseek-math-7b-rl-5500steps",
    trust_remote_code=True
)

# Solve a math problem
prompt = """Solve the following mathematics problem step by step:

Problem: Find the sum of all positive integers n such that n² + 3n + 2 is a perfect square.

Solution:"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(
    **inputs,
    max_new_tokens=500,
    temperature=0.7,
    do_sample=True
)

solution = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(solution)
```

### Example Outputs

**Example 1: AIME Problem**
```
Problem: Find the remainder when 2^100 is divided by 101.

Solution:
By Fermat's Little Theorem, since 101 is prime:
2^100 ≡ 1 (mod 101)

The remainder is 1.
```

**Example 2: Calculus**
```
Problem: Evaluate ∫ x² e^x dx

Solution:
Using integration by parts twice:
∫ x² e^x dx = x² e^x - 2∫ x e^x dx
= x² e^x - 2(x e^x - e^x) + C
= e^x(x² - 2x + 2) + C
```

## Model Architecture

- **Architecture**: Decoder-only Transformer
- **Parameters**: 6.91B
- **Hidden Size**: 4096
- **Layers**: 30
- **Attention Heads**: 32
- **Context Window**: 4096 tokens
- **Vocabulary Size**: 102,400

## Training Infrastructure

- **GPU**: NVIDIA GH200 480GB unified memory
- **Training Time**: ~24 hours
- **Framework**: PyTorch 2.4 + Transformers 4.41
- **Optimizer**: AdamW with cosine scheduling

## Intended Use

### Primary Use Cases
1. **Competition Math Preparation**: AIME, AMC, MATH dataset
2. **Problem Solving Assistance**: Step-by-step solutions
3. **Educational Tool**: Learning mathematics concepts
4. **Research**: Mathematical reasoning capabilities

### Limitations
- Optimized for competition-style problems
- May not handle informal or ambiguous problems well
- Requires clear, well-structured problem statements
- Not suitable for multi-modal (image) problems without vision encoder

## Ethical Considerations

- **Educational Use**: Designed to help students learn, not replace learning
- **Cheating Concerns**: Should not be used in actual competitions
- **Accuracy**: While highly accurate, always verify solutions for critical applications
