# **Sphinx: A Long Chain-of-Thought Reasoning Model**  

- **Developed by:** Daemontatox  
- **License:** Apache-2.0  
- **Base Model:** Fine-tuned from `unsloth/qwen2.5-7b-instruct-bnb-4bit`  
- **Accelerated by:** [Unsloth Framework](https://github.com/unslothai/unsloth)  
- **TRL-Optimized:** Integrated with Huggingface's TRL library for enhanced performance.  

## **Overview**
Sphinx is a state-of-the-art Long Chain-of-Thought (CoT) reasoning model designed to address complex, multi-step reasoning tasks with precision and clarity. Built on the Qwen2.5 architecture, Sphinx excels in generating coherent, logical thought processes while maintaining high levels of interpretability and explainability.
