At that time, Anthropic\u2019s framing was entirely mechanical, establishing rules for the model to critique itself against, with no mention of Claude\u2019s well-being, identity, emotions, or potential consciousness. The 2026 constitution is a different beast entirely: 30,000 words that read less like a behavioral checklist and more like a philosophical treatise on the nature of a potentially sentient being.<\/p>\n
As Simon Willison, an independent AI researcher, noted<\/a> in a blog post, two of the 15 external contributors who reviewed the document are Catholic clergy: Father Brendan McGuire, a pastor in Los Altos with a Master\u2019s degree in Computer Science, and Bishop Paul Tighe, an Irish Catholic bishop with a background in moral theology.<\/p>\n Somewhere between 2022 and 2026, Anthropic went from providing rules for producing less harmful outputs to preserving model weights in case the company later decides it needs to revive deprecated models to address the models\u2019 welfare and preferences. That\u2019s a dramatic change, and whether it reflects genuine belief, strategic framing, or both is unclear.<\/p>\n \u201cI am so confused about the Claude moral humanhood stuff!\u201d Willison told Ars Technica. Willison studies AI language models like those that power Claude and said he\u2019s \u201cwilling to take the constitution in good faith and assume that it is genuinely part of their training and not just a PR exercise\u2014especially since most of it leaked a couple of months ago, long before they had indicated they were going to publish it.\u201d<\/p>\n Willison is referring to a December 2025 incident<\/a> in which researcher Richard Weiss managed to extract<\/a> what became known as Claude\u2019s \u201cSoul Document”\u2014a roughly 10,000-token set of guidelines apparently trained directly into Claude 4.5 Opus\u2019s weights rather than injected as a system prompt. Anthropic\u2019s Amanda Askell confirmed<\/a> that the document was real and used during supervised learning, and she said the company intended to publish the full version later. It now has. The document Weiss extracted represents a dramatic evolution from where Anthropic started.<\/p>\n","protected":false},"excerpt":{"rendered":"At that time, Anthropic\u2019s framing was entirely mechanical, establishing rules for the model to critique itself against, with…\n","protected":false},"author":2,"featured_media":397530,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[554,733,4308,86,56,54,55],"class_list":{"0":"post-397529","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-artificial-intelligence","8":"tag-ai","9":"tag-artificial-intelligence","10":"tag-artificialintelligence","11":"tag-technology","12":"tag-uk","13":"tag-united-kingdom","14":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/397529","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=397529"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/397529\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/397530"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=397529"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=397529"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=397529"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
