# Deepthought-8B

Deepthought-8B is a small and capable reasoning model built on LLaMA-3.1 8B, designed to make AI reasoning more transparent and controllable. Despite its relatively small size, it achieves sophisticated reasoning capabilities that rival much larger models.

## Model Description

Deepthought-8B is designed with a unique approach to problem-solving, breaking down its thinking into clear, distinct, documented steps. The model outputs its reasoning process in a structured JSON format, making it easier to understand and validate its decision-making process.

### Key Features

- **Transparent Reasoning**: Step-by-step documentation of the thought process
- **Programmable Approach**: Customizable reasoning patterns without model retraining
- **Test-time Compute Scaling**: Flexible reasoning depth based on task complexity
- **Efficient Scale**: Runs on 16GB+ VRAM
- **Structured Output**: JSON-formatted reasoning chains for easy integration

## Technical Requirements

- Python 3.6+
- PyTorch
- Transformers library
- 16GB+ VRAM
- Optional: Flash Attention 2 for improved performance

## Installation

```bash
pip install torch transformers
# Optional: Install Flash Attention 2 for better performance
pip install flash-attn
```

## Usage

1. First, set your HuggingFace token as an environment variable:
```bash
export HF_TOKEN=your_token_here
export HF_HUB_ENABLE_HF_TRANSFER=1
```

2. Use the model in your Python code:
```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Initialize the model
model_name = "ruliad/deepthought-8b-llama-v0.01-alpha"
tokenizer = AutoTokenizer.from_pretrained(
    model_name,
    add_bos_token=False,
    trust_remote_code=True,
    padding="left",
    torch_dtype=torch.bfloat16,
)

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map="auto",
    attn_implementation="flash_attention_2",  # Use "eager" (or omit) if flash_attn is not installed
    use_cache=True,
    trust_remote_code=True,
)
```

3. Run the provided example script:
```bash
python deepthought_inference.py
```

## Example Output

The model provides structured reasoning in JSON format:

```json
{
  "step": 1,
  "type": "problem_understanding",
  "thought": "Understanding the user's objective for the task."
}
```

Each reasoning chain includes multiple steps:
1. Problem understanding
2. Data gathering
3. Analysis
4. Calculation (when applicable)
5. Verification
6. Conclusion drawing
7. Implementation

## Performance

Deepthought-8B demonstrates strong performance across various benchmarks:
- Step-by-step problem-solving
- Coding and mathematical tasks
- Instruction following with transparent reasoning
- Scalable performance with test-time compute

## Limitations

Current known limitations include:
- Complex mathematical reasoning
- Long-context processing
- Edge case handling

## License

The model is available under a commercial license for enterprise use.
