On 12th September 2024, OpenAIannounced the launch of its o1-series models, marking a pivotal moment in artificial intelligence (AI) development. Focused on enhancing AI’s reasoning abilities, the new series aims to tackle complex challenges in STEM fields such as mathematics, coding, and scientific analysis. The flagship o1-preview model demonstrates an ability to think more strategically and solve difficult problems with greater accuracy, paving the way for a new era of AI capabilities.
OpenAI o1 — our first model trained with reinforcement learning to think hard about problems before answering. Extremely proud of the team!
This is a new paradigm with vast opportunity. This is evident quantitatively (eg reasoning metrics are already a step function improved)… https://t.co/rj0wMh4Sec
“We’ve developed a new series of AI models designed to spend more time thinking before they respond,” OpenAI officials noted, underlining the model’s more thoughtful and dynamic problem-solving approach. This series builds upon prior models, delivering improved reasoning performance across a variety of advanced tasks.
Superior Problem-Solving Abilities
The standout feature of the o1-series is its adeptness at solving intricate problems, particularly in mathematics and coding. The o1-preview model demonstrated impressive results in the International Mathematics Olympiad (IMO), achieving a remarkable 83% success rate, vastly outperforming its predecessor, GPT-4o, which solved only 13% of the same problems. In addition, the model excelled in Codeforces competitions, ranking in the 89th percentile for coding challenges.

This model’s strength lies in its ability to break problems down step-by-step, akin to human logical reasoning. Bob McGrew, OpenAI’s Chief Research Officer, expressed his amazement at the model’s proficiency, joking, “The model is definitely better at solving the AP math test than I am, and I was a math minor in college.”
Cost-Efficient Alternative: OpenAI o1-Mini
In addition to the o1-preview, OpenAI introduced the o1-mini, a smaller, faster, and more affordable version. Designed to be 80% cheaper than the o1-preview, the o1-mini provides comparable performance in key areas, making it ideal for developers and researchers looking for a more cost-effective solution. It particularly shines in STEM reasoning, scoring 70% in the AIME mathematics competition compared to o1-preview’s 74.4%.
This cost-efficient option allows users to enjoy many of the reasoning benefits of o1-preview without requiring extensive computational resources, making it more accessible to a wider audience.
Enhanced Safety and Ethical AI Deployment
A major focus for the o1-series has been the integration of improved safety features. With concerns around AI safety continuing to dominate the conversation, OpenAI has placed a significant emphasis on ensuring that its models adhere to stringent alignment guidelines. The o1-preview scored an impressive 84/100 on OpenAI’s toughest jailbreak tests, compared to GPT-4o’s mere 22/100.

In collaboration with the U.S. and U.K. AI Safety Institutes, OpenAI has allowed early access to the o1-series for research and testing purposes, ensuring rigorous evaluation of its safety mechanisms. Spotlighting, a new feature within the models, helps the AI distinguish between valid and potentially harmful instructions, furthering OpenAI’s commitment to ethical deployment.
Real-World Applications and Industry Integration
The o1-series is already being adopted across various industries. For instance, GitHub Copilot is integrating the model to enhance developers’ capabilities in code optimisation and debugging. Thomas Dohmke, CEO of GitHub, noted, “With o1 and its strong reasoning capabilities, GitHub Copilot will enable developers to build for the bigger picture, faster.”
Additionally, the model’s impact extends to legal services, where Harvey, a legal AI platform, is exploring o1’s potential for drafting contracts and conducting due diligence. Winston Weinberg, CEO and Co-Founder of Harvey believes that “o1 could handle complex legal tasks, bridging the gap between AI-powered chatbots and more collaborative professional tools.”
Challenges and Future Developments
Despite its advanced reasoning capabilities, the o1-series has limitations. The model lacks broad-world knowledge and cannot process files or images, which restricts its versatility. Furthermore, its steep pricing poses a challenge, particularly for budget-conscious developers, as API access costs $15 per 1 million input tokens and $60 per 1 million output tokens.
Looking ahead, OpenAI plans to enhance the models further by adding features like file uploading, browsing, and image support. This evolution aims to broaden the model’s use cases and make it more accessible to a diverse range of users.
Conclusion
The OpenAI o1-series represents a monumental step forward in AI’s reasoning capabilities, particularly within the STEM fields. While the models’ higher cost and certain limitations may restrict their widespread adoption, their problem-solving efficiency, safety features, and industry integration signal a transformative moment in AI development. With continued advancements, OpenAI’s o1-series is poised to reshape how complex tasks are approached across industries, from software development to healthcare.
