This report details the research process of a team of researchers at Shanghai Jiao Tong University and other institutions who are attempting to replicate OpenAI's O1 model, a groundbreaking language model capable of complex reasoning. The report advocates for open science by detailing the entire research journey, including successes and failures, to help other researchers accelerate progress in the field. The researchers have introduced a new paradigm called "journey learning," where models learn not just shortcuts to solutions, but the entire exploration process, including trial and error and reflection, which they believe is key to O1's capabilities. They share valuable resources including technical hypotheses, cognitive exploration maps, and custom-developed tools. The report also highlights the challenges of traditional AI research and proposes a new framework for scientific communication and collaboration.
