OpenThinker-32B: Enhanced Reasoning Model

OpenThinker-32B is a 32.8 billion parameter model developed by shaffhausen, fine-tuned from Qwen/Qwen2.5-32B-Instruct. Its primary distinction lies in its training on the unique OpenThoughts-114k dataset, which is derived by distilling DeepSeek-R1. This specialized training focuses on improving the model's performance in complex reasoning and mathematical problem-solving.
