Frontier AI is the most important technology of our time. In just the past few years, AI capabilities have improved from amusing to awe-inspiring. These systems have begun pushing forward scientific fields such as mathematics, acting autonomously and through self-organization to accomplish difficult goals, and playing an essential role in the lives of hundreds of millions. The pace of progress does not seem set to slow down, and decisions about who bears the risks, who gets the benefits, and what institutions are necessary to govern advanced AI are the most important political issues today.

Many of the problems we face here are fundamentally constitutional, having to do with the basic structure and pattern of life together. AI governance is both concerned with concrete risks to human safety and also with how to ensure that AI advances in a way that is broadly good, responsive to the democratic will, and protective of the basic liberties that let people find their own best ways to live, alone and together. How do we distribute and balance power, so that catastrophic risks are prevented and so that no person, system, company, or party can predominate over others? What do governments or companies owe to citizens whose jobs are automated away and who then do not have the means to independently provide for themselves? Do AIs deserve membership in our political communities, or someday will they? If we do not make these decisions ourselves, they will be made for us, and often by people with personal rather than public interests at heart.<br>These days, we ask again “the important question, whether societies of men are really capable or not of establishing good government from reflection and choice, or whether they are forever destined to depend for their political constitutions on accident and force.” And maybe today our questions are harder than those confronted by those who came before us, with greater forces at work in the world and the very definition of society stretching in the face of new intelligences beginning to act and be alongside us. These are constitutional considerations that sit at the heart of who we are and are becoming, and they are the subject of Model Constitution.<br>Our questions have answers, if we have the wit and the will to find them. I plan to dedicate the first substantive posts of Model Constitution to one of the most literal interpretations of its title: looking at Claude’s Constitution and the OpenAI Model Spec, the closest things we have to constitutional texts in frontier AI and documents that “constitute” their models. We’ll be looking into what these texts are, how they work, and what they might tell us about how power operates in the world of frontier AI. Legal and political theory have lots of questions for them and even some answers, though fewer than we’d hope.

To address constitutional AI governance, we must take the AI constitutions seriously, and ask what makes them legitimate; what rights they grant and with what remedies; who interprets and enforces them; if and how they interact with external institutions; and what they mean for the people and artificial intelligences they govern. Model Constitution will broaden to begin addressing a larger set of constitutional questions, having to do with how AI changes the distribution of power and the legitimacy of its exercise, the rights and obligations that we have and should have in this transformative time, and how existing institutions will engage with and affect AI and its governance.<br>Eventually, Model Constitution will host an actual model AI constitution, a document that is both a technical specification toward which to align advanced AI and a description of a political order through which to govern AI for broad benefit. The Model Constitution will be an exemplar and a point of comparison against which the constitutions of the AI companies can be considered. It will be able to interface with external checking and balancing institutions and integrate public deliberation in ways that company constitutions cannot. In collaboration with others, I hope to help advance the open science of technical AI governance through experiments run on the Model Constitution that align and then evaluate AI systems.<br>The Model Constitution will be mostly written from my perspective and with public engagement. I (and hopefully other interested people) will defend it and the views it takes. But the goal is not to provide a perfect target for alignment, only to provide a decent one that others can take as a model to help decide how to think about these difficult questions. I believe that through deliberation and research we can align AI for the public good, and I hope that this project will advance that program. Over time, I hope more...
