The project was spearheaded by prominent figures in the AI field, including OpenAI co-founder Ilya Sutskever, chief research officer Mark Chen, and chief scientist Jakub Pachocki.
OpenAI had to allocate significant resources, such as talent and GPUs, to create the o1 model. The company’s history of prioritizing breakthroughs in AI research played a crucial role in securing resources for the project. The focus on developing AGI, rather than specific products, allowed OpenAI to prioritize the o1 model over other efforts, leading to significant advancements in AI reasoning models.
By late 2024, traditional pretraining scaling methods were showing diminishing returns, prompting leading AI labs to explore new training techniques. The emphasis on reasoning models has since become a driving force in the AI field, with many breakthroughs centered around this concept.
The concept of AI reasoning raises questions about what it means for an AI system to “reason.” While definitions may vary, researchers at OpenAI emphasize the model’s capabilities and outcomes over specific definitions. The focus is on creating powerful and useful AI tools, regardless of how they achieve their results.
AI reasoning models are still not well understood, and more research is needed to unravel the complexities of these systems. Despite the ongoing debate around the definition of reasoning in AI, researchers agree that the capabilities of these models are paramount.

While current AI agents excel in well-defined domains, they struggle with complex, subjective tasks. Researchers are working on training models to tackle these more nuanced tasks, but challenges remain in data availability and verification.
OpenAI is at the forefront of developing new general-purpose RL techniques to teach AI models skills that are not easily verified. Researchers like Noam Brown are exploring innovative approaches to training AI models on less verifiable tasks, paving the way for advancements in AI agents for subjective tasks. The journey towards building the model that achieved a gold medal at the International Math Olympiad (IMO) was a significant milestone for the company. OpenAI’s IMO model represented a new frontier in AI technology, utilizing a system that spawned multiple agents to explore various ideas simultaneously and select the most optimal solution. This approach has been gaining traction in the AI community, with tech giants like Google and xAI also unveiling cutting-edge models using similar techniques.
According to Brown, the rapid progress in developing these AI models indicates a promising future not only in math but also in other reasoning domains. The continuous advancements in AI capabilities suggest that there is no sign of slowing down, paving the way for more sophisticated and versatile AI systems.
The success of OpenAI’s IMO model lays the groundwork for the company’s upcoming GPT-5 model, which aims to set new standards in AI technology. With the launch of GPT-5, OpenAI envisions consolidating its position as a leader in the industry, providing developers and consumers with the most advanced AI model available.
