• Developed by: Daemontatox
• License: Apache-2.0
• Base Model: Fine-tuned from unsloth/qwen2.5-7b-instruct-bnb-4bit
• Accelerated by: Unsloth Framework
• 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.
