Summary
OpenAI introduces 'deliberative alignment,' a technique that explicitly encodes safety specifications into the model's reasoning process, allowing the model to consciously consider guidelines before responding. Rather than relying solely on implicit behavioral training, this approach teaches models to reason about and reference safety policies during inference, improving both safety compliance and instruction-following without sacrificing capability.
Key Points
- •Deliberative alignment teaches models to explicitly reason about safety specifications before generating responses, rather than relying only on implicit learned behaviors.
- •The approach encodes OpenAI's safety policies directly into the chain-of-thought reasoning, allowing models to consciously consult guidelines during inference.
- •This method aims to reduce over-refusal and improve nuanced safety decisions by grounding responses in reasoned policy interpretation rather than pattern-matching.
- •Deliberative alignment is presented as complementary to RLHF and other alignment techniques, forming part of a layered safety strategy.
- •The technique is deployed in OpenAI's o-series reasoning models, representing a practical application of reasoning-based safety approaches.

We introduce deliberative alignment, a training paradigm that directly teaches reasoning LLMs the text of human-written and interpretable safety specifications, and trains them to reason explicitly about these specifications before answering. We used deliberative alignment to align OpenAI’s o-series models, enabling them to use chain-of-thought (CoT) reasoning to reflect on user prompts, identify relevant text from OpenAI’s internal policies, and draft safer responses. Our approach achieves highly precise adherence to OpenAI’s safety policies, and without requiring human-labeled CoTs or answers. We find that o1 dramatically outperforms GPT‑4o and other state-of-the art LLMs across a range of internal and external safety benchmarks, and saturates performance on many challenging datasets. We believe this presents an exciting new path to improve safety, and we find this to be an encouraging example of how improvements in capabilities can be leveraged to improve safety as well.
