Defining Constitutional AI: Anthropic's Principles for Helpful, Honest, Harmless AI

Constitutional AI refers to a set of principles and norms that govern the behavior of advanced AI systems. These principles are grounded in ethical and social considerations such as transparency, accountability, fairness, and human rights.

Anthropic, an AI safety company, has developed 16 key principles to guide the development of constitutional AI models. These principles emphasize choosing the most helpful, honest, and harmless AI responses.

Goals of the Constitutional AI Model

The goal of Anthropic's Constitutional AI (rlci) model is to produce helpful, honest, and harmless conversational responses. The model has been fine-tuned on Anthropic's existing 52-billion parameter model and trained via reinforcement learning from AI feedback, rather than only human feedback. During this reinforcement learning process, the model is assessed on its adherence to Anthropic's 16 principles for helpful, honest and harmless AI. The model's responses aim to avoid toxicity, racism, sexism or other forms of harm.

Methodology Behind the Constitutional AI Model

Anthropic utilizes a two-stage approach in developing its Constitutional AI model. First is a supervised learning stage where the model is critiqued and responses are revised based on principles of helpfulness, honesty and harmlessness.

The second stage employs reinforcement learning using an AI evaluation model to provide feedback and compare AI responses. This allows further fine-tuning of the model to align better with Constitutional AI principles.

Assessing Progress in Constitutionally-Aligned AI

Experiments indicate the Constitutional AI model shows reduced harmfulness compared to benchmark models, while maintaining helpfulness - though there is still room for improvement.

Specifically, the inclusion of "chain of thought" prompting leads to slightly more harmless (but also slightly less helpful) responses, illustrating an interesting tradeoff between helpfulness and harmlessness objectives.

FAQ

Q: What is constitutional AI?
A: Constitutional AI refers to principles and norms that guide advanced AI systems to behave helpfully, honestly, and harmlessly based on ethical considerations.

Q: How does anthropic build constitutional AI models?
A: Anthropic develops constitutional AI models like Claude through techniques like reinforcement learning from AI feedback and adherence to principles for harmless dialogue.

Q: How effective is constitutional AI?
A: Research indicates constitutional AI models can be slightly more helpful and harmless than human-in-the-loop benchmarks, but further innovation is needed.
