  "transcript": "I'm in the U.S. and my settings are set to \"English (United States).\" I noticed about two weeks ago that Claude suddenly started using mostly British spelling in both its thinking summaries and responses.\n\nA few examples:\n\n* Colour\n* Recognise\n* Enrolment\n* Defence\n* Analyse\n* Behaviour\n\nI asked Claude why the spelling had changed, and it said it didn't know and described it as \"drift.\"\n\nIt doesn't really affect anything, but I'm curious whether anyone else has noticed the same thing recently?\n\nEDIT: I'm not using a VPN.\n\n\n\n--- Top Comments ---\n\n\n[1 upvotes] **TL;DR of the discussion generated automatically after 50 comments.**\n\nSo, what's the deal with Claude suddenly sounding like it's about to ask for a \"cuppa\"? **The overwhelming consensus is yes, this is happening to a lot of people, and the community has decided it's because Claude is getting smarter.**\n\nThis thread is mostly a pile-on against American English, with the top comments all joking that Claude is simply upgrading to the \"correct\" or \"true\" version of the language. The new proposed language settings are now \"English (Traditional)\" and \"English (Simplified).\"\n\nWhile a few users floated serious theories about server routing or watermarking, most are just happy to see the AI \"evolve.\" Basically, the Brits think they've successfully colonised the AI and the rest of you will just have to deal with it. Cheerio, mate.\n\n[105 upvotes] Because British English is true English. Deal with it. \n\n[74 upvotes] I reckon all of us over the pond have told it off so many times it's stuck. Be careful of it'll start using pounds for currency and metric measurements...\n\n[42 upvotes] Why would anybody be surprised that the more advanced an AI model gets, the more it prefers to spell things correctly?",
