OpenAI's o1 and o3: Thinking About Safety Policy

OpenAI's latest models, o1 and o3, have been trained to consider safety principles in their decision-making processes. This approach marks a significant shift in prioritizing safety and reliability in AI systems. By integrating safety considerations into the training process, OpenAI aims to create more responsible and trustworthy models.

The training of o1 and o3 involved a combination of techniques, including reinforcement learning (RL), chain-of-thought prompting (CoT), and human-in-the-loop (HITL) evaluation. These methods enabled the models to learn from human feedback, generate detailed reasoning steps, and improve their adherence to safety guidelines.

Reinforcement learning played a pivotal role in teaching o1 and o3 to adhere to OpenAI's safety principles. The models were trained to optimize their responses based on feedback, with a reward function that encouraged safe, coherent, and relevant outputs. This process allowed the models to develop a deep understanding of OpenAI's safety principles and incorporate them into their decision-making processes.

The models' responses were evaluated and refined through a rigorous process involving human feedback and iterative improvement. Human evaluators reviewed the models' outputs, providing feedback on their safety, relevance, and coherence. Based on this feedback, the models were continually refined and improved, ensuring their responses aligned with desired safety standards.

OpenAI's approach to training o1 and o3 reflects the company's commitment to developing AI systems that prioritize safety and benefit users. By integrating safety considerations into the training process, OpenAI aims to create models that are not only more capable but also more responsible and reliable.


The integration of safety principles into the training of o1 and o3 has led to improved performance in safety-critical tasks. The models have demonstrated an ability to detect and mitigate potential risks, making them more reliable and trustworthy for users.


In conclusion, OpenAI's approach to training o1 and o3, with a focus on safety considerations, has resulted in more responsible and reliable models. By combining reinforcement learning, chain-of-thought prompting, and human-in-the-loop evaluation, OpenAI has created models that prioritize safety and benefit users. The positive impact of this approach on the performance of o1 and o3 underscores the importance of continued investment and innovation in AI safety and reliability.
