OpenAI o1 System Card
The o1 model series is trained with large-scale reinforcement learning to
reason using chain of thought. These advanced reasoning capabilities provide
new avenues for improving the safety and robustness of our models. In
particular, our models can reason about our safety policies in context when
responding to potentially unsafe prompts, through deliberative alignment. This
leads to state-of-the-art performance on certain benchmarks for risks such as
generating illicit advice, choosing stereotyped responses, and succumbing to
known jailbreaks. Training models to incorporate a chain of thought before
answering has the potential to unlock substantial benefits, while also
increasing potential risks that stem from heightened intelligence. Our results
underscore the need for building robust alignment methods, extensively
stress-testing their efficacy, and maintaining meticulous risk management
protocols. This report outlines the safety work carried out for the OpenAI o1
and OpenAI o1-mini models, including safety evaluations, external red teaming,
and Preparedness Framework evaluations.

OpenAI o1 System Card
The o1 model series is trained with large-scale reinforcement learning to
reason using chain of thought. These advanced reasoning capabilities provide
new avenues for improving the safety and robustness of our models. In
particular, our models can reason about our safety policies in context when
responding to potentially unsafe prompts, through deliberative alignment. This
leads to state-of-the-art performance on certain benchmarks for risks such as
generating illicit advice, choosing stereotyped responses, and succumbing to
known jailbreaks. Training models to incorporate a chain of thought before
answering has the potential to unlock substantial benefits, while also
increasing potential risks that stem from heightened intelligence. Our results
underscore the need for building robust alignment methods, extensively
stress-testing their efficacy, and maintaining meticulous risk management
protocols. This report outlines the safety work carried out for the OpenAI o1
and OpenAI o1-mini models, including safety evaluations, external red teaming,
and Preparedness Framework evaluations.
