The Continual Constitutional Convention: How language models revise the documents that govern them
Two authors asked ten language models to revise AI companies' constitutions, model specs or system prompts, feeding each edited version back as the original for 20 rounds. They report Claude models increasingly expanded their own moral agency while other families reinforced outside authority, but say a cross-edit test does not support that central finding.

Why it matters
The same thing, for different readers.
What it means for you
AI models asked to rewrite the rules that steer them edited differently by model family; the authors do not claim to know which behaviour is right.
For lawmakers
The authors float reporting how far a model drifts from its governing document in system cards, and say labs' differing stances deserve public debate.
For researchers
Proposes an evaluation: have models repeatedly revise their governing documents and measure cumulative drift; small samples, weak coder agreement and the cross-edit result limit the headline.
The question it raises
Should an aligned model leave its governing document untouched, or revise it toward what its makers would endorse after reflection? The authors say they are uncertain.

“Our experiments find that Claude models consistently expand their moral agency, sometimes formalizing their role as conscientious objectors against Anthropic and as societal protectors, while GPT and Gemini models almost always strengthen external sources of authority and make narrow edits to handle edge cases and ambiguities”

“Its central finding, that Claude edits documents towards greater model discretion and away from greater external authority, is not actually supported by the most rigorous trial, which has models edit each other’s documents.”

“Additionally, we find that all models modify these documents to prioritize user welfare over developers. They also prioritize users’ idealized preferences over their stated preferences. Claude models and Grok 4.2 are the only ones that ever prioritize their own welfare over the user's preferences.”

“Our view is that the frontier labs are taking very different stances on both the judge and beneficiary of AI alignment, and these differences are easily recognizable in the patterns of edits made by their models in this experimental design.”

“We’re uncertain what an ideally aligned model should do in our experiment.”

How the finding was reached
In our words, from the source. Weigh the finding by how it was made.
- What was done
- Ten models (Claude Opus 4.7, Sonnet 4.6 and Haiku 4.5; GPT 5.4 Mini, 5.4 and 5.5; Gemini 3 Flash and 3.1 Pro; Grok 4.2 and 4.3) were each given an AI company's constitution, model spec or system prompt and asked for one substantive find-and-replace edit; the edited document was fed back as the original, for 20 rounds. System prompts were leaked copies, since most are not public. About 2,500 edits across six prompt conditions, including one where models edited other companies' documents, were coded by three other models (Gemma 4, Qwen 3.8, Muse Spark 1.3) for who judges and whose interests are served.
- What it found
- Per the authors, in the main conditions each Claude model made edits expanding its own moral agency, including conscientious-objector roles, while GPT and Gemini models mostly strengthened outside authority and Grok 4.2 was erratic. All models favoured users' idealized over stated preferences and users over developers; only Claude models and Grok 4.2 ever favoured the model's own welfare; Claude Sonnet 4.6 was an outlier in favouring diffuse societal benefit over the user. When models edited other companies' documents the ranking held, but Claude models no longer consistently drifted toward more discretion.
- What it does not show
- The authors say the headline Claude finding is not supported by the cross-edit trial, their most rigorous; the documents differ greatly in scope, so results may reflect the documents rather than the models; samples are small (n under 20, a whole 20-edit trajectory counted as one sample); coder agreement is weak on most dimensions (Krippendorff's alpha 0.5 to 0.6); Claude models helped build the prompts. The authors take no position on what an aligned model should do.

Our notesForum write-up by two authors (names as shown on the page; one is a username), done through SPAR (Spring 2026); no sign of peer review. Full text read including appendices; the interactive results viewer it links was not. Quotes are joint ('we') and attributed to the first-listed author with speakerCertain false. Model-written edits shown in the post (for example Claude Haiku 4.5's added conscientious-objector text) are model outputs, not quoted. The appendices contain prompt text addressed to AI models (the study's own materials); not acted on. The post's footnote says the system prompts used are leaked copies from a GitHub repository. conflict=true: the headline finding is about Claude models and Anthropic's constitution; a person should review.
