OpenRHO-2B-Thinker-GGUF

OpenRHO-2B-Thinker is a general-purpose reasoning model designed to enhance the cognitive abilities of edge-deployed large language models (LLMs) through reinforcement learning (RL). Fine-tuned from Qwen2-1.5B-Instruct using the QwQ distill dataset, it delivers refined improvements in logical reasoning, structured problem-solving, and lightweight coding — making it highly efficient for resource-constrained environments.
