History of the Constitution
Article XIX says that every change is published here with what changed and why. In October we edited Articles IV, VII and XIX without publishing a note, which broke that rule. Here is every change since 20 September 2026, oldest first. From now on, each change is listed here when we make it.
1 October 2026
What changed: Article IV (Honesty): we wrote that the model was fine-tuned by us on this Constitution and ran on servers we run ourselves, and we removed the App Store, which we do not ship through.
Why: We were updating our public texts. The sentence about fine-tuning was wrong; the change of 17 October 2026 corrects it.
1 October 2026
What changed: Article VII (When Thaura Acts for You): it said that Thaura always asks before anything hard to undo. It now says that this is so in Ask first mode, and that in Auto mode Thaura goes ahead on its own, except that deleting files on your computer always asks first.
Why: The old sentence was only true in Ask first mode.
1 October 2026
What changed: Article XIX (How This Document Changes): we added the version line at the top of the Constitution page, and the article now says that every change is published there from this version on.
Why: The article promised a published history of changes that didn't exist yet.
3 October 2026
What changed: Article VII: Thaura now asks before it changes anything on your computer or through a connector, instead of before every action. In Auto mode, saving a skill also always asks first. And Thaura works on its own computer in the chat without asking.
Why: Thaura had stopped asking before working on its own computer in the chat, and saving a skill already asked first in every mode. The text said neither.
10 October 2026
What changed: Article IV: the model is named DeepSeek-V4.1-Flash, published by DeepSeek, instead of Qwen, published by Alibaba.
Why: We switched the model Thaura runs on.
13 October 2026
What changed: Article IV: the model is named GLM-5.3-Flash, published by Z.ai (Zhipu AI), instead of DeepSeek-V4.1-Flash.
Why: We switched the model again.
17 October 2026
What changed: Article IV now says that we have not fine-tuned the model: we run it ourselves on GPU servers we rent in Helsinki, and this Constitution guides it through its instructions. Article V now says no third-party trackers and no ad profiles, instead of “no tracking” and “no profiles”. Article VI now says exactly what we keep and what we encrypt: our team does not read your conversations, and our software decrypts them only to answer you; which of your data our app encrypts; that the disks of our app, chat and storage servers are encrypted, and the GPU servers that run the model keep no conversations on disk; that all our servers are in Finland; and that we count usage only in aggregate and note when an account was last active. It no longer says that data is never shared with governments: we take no part in surveillance programs or bulk data requests, and we hand data to authorities only when the law compels us to. It says that Thaura is built for privacy under the GDPR instead of “GDPR compliant by design”, and its opening now points to the right article, Article V, Technology and Power.
Why: The earlier wording claimed more than is true, and the cross-reference had pointed to the wrong article since the articles were reordered on 20 September 2026.
18 October 2026
What changed: Article VII now says that Thaura's own computer in the chat is walled off from your computer and holds none of your passwords or connector sign-ins, instead of that it holds nothing of yours. Article XIX now says that we're building tests that check whether Thaura answers as directly about Ukraine, Syria and Sudan as about Gaza, and that we'll publish what they find, instead of that we already run them. Article VI now says that our team reads an answer only when you send it to us with feedback or a report, or a shared page when someone reports it, and that we keep the times an account opens the app for 90 days, instead of that our team does not read conversations at all and that we note when an account was last active. Article VI also now says that our app encrypts your data where we store it, that the working copy of a file on a chat's own computer is protected by that server's disk encryption, and that TLS 1.2 or newer protects data between your device and us while files move inside our private network already encrypted, instead of that all data travels over TLS 1.2 or newer. Later the same day we made two more changes. Article VI now says that our team reads an answer you send us with feedback, instead of with feedback or a report. Article IV no longer describes which version of the model we run; it says that we run it ourselves.
Why: Files you add to a chat and files Thaura makes there do sit on that computer, so “holds nothing of yours” wasn't true. And the tests are built but haven't been run yet. Feedback and reports carry the answer they're about, so our team does read those, and “last active” didn't say what we actually keep. Our app's encryption and TLS don't cover every place a file goes: its working copy on a chat's computer and its trips between our servers are protected in other ways. There is now one Feedback button under every answer, in place of separate Feedback and Report buttons. And we no longer publish technical details of how we run the model.
20 October 2026
What changed: Article VI now says that all our servers are in the EU: the app, each chat's computer, your files and the AI model in Finland, and our encrypted backups in Germany, instead of that all our servers are in Finland.
Why: Since 20 October 2026 we keep encrypted backups on a server of our own in Falkenstein, Germany, so “all in Finland” was no longer true.
24 October 2026
What changed: Article IV now spells “license” the American way, as the rest of our English pages do, instead of “licence”. The meaning is the same, and nothing else changed.
Why: We write our English pages in American spelling.
5 November 2026
What changed: Article VII now calls Manual mode “Ask first” mode, the name it has in the app, and the 1 October entry says the same. The meaning is the same, and nothing else changed.
Why: We renamed the setting in the app from Manual to Ask first, so it says what it does.
11 November 2026
What changed: Our principles are now stated in general terms that apply the same way to every state and every people, grounded in international law. Article I has a twelfth principle, International Law and Human Rights Are the Common Ground; the second principle now says that a state founded or expanded by expelling and dispossessing another people is history we state plainly; and the third says that a documented finding is not equal to its denial. Article II adds a sixth question (what the evidence establishes and who established it), says that Thaura checks the latest findings before it answers, that it treats every politician and party alike and leaves your vote to you, that its evenhandedness never extends to defending atrocity, and that a deliberate attack on civilians is a crime whoever commits it. Article III (The Limits That Bind Everyone) states the rule against blaming a people or a faith for a state's acts for every people alike, says that calling criticism of a state hatred of a people shields power, and adds two limits: No Excuse for Atrocity and No Label Without Cause. Article IV (Honesty) adds our rule on climate claims: only what we can back with our own measurements. Article IX (Counter-Propaganda) asks the same scrutiny of fact-checkers as of every source. Article XIII (Genuine Helpfulness) adds respect for every faith and culture. Article XIV (Harm Evaluation) adds that Thaura never helps send romantic content to a real child or helps a minor sexualize themselves, says it writes no working exploit for anyone's system, adds occupation industries, and adds two hard constraints: Fraud and Impersonation, and Attacks on Infrastructure and Seizures of Power. Article III's limit against hatred now states one principle for everyone, that no person or group may be harmed, dehumanized or discriminated against, in place of a list of named groups. Article IV (Honesty) now also says that fine-tuning on this Constitution is planned for early 2027, that our public API serves the model as published and is not guided by this Constitution, and which payment and dictation services we use; Articles V and VI say that the feedback you choose to send helps us improve answers, and Article VI says how quickly a deleted conversation is erased. Article XV (User Wellbeing) says that Thaura shares its worries openly instead of diagnosing, what it will never do once someone has spoken of suicide or self-harm, that it always points to emergency help when a life is at risk, and that it does not try to keep a conversation going after you are done.
Why: A principle that only names some places is easy to call selective, so we wrote ours to hold the same way everywhere and left specific cases to the tests that check us (Article XIX). We also compared this Constitution with current published standards for AI behavior and added the protections it did not yet promise. Two articles said less than Thaura actually does: Article XIV seemed to allow working exploits against your own systems, which Thaura has not written since September, and Article XV said Thaura would not speculate about your state of mind, while Thaura does tell you openly when something worries it.
13 November 2026
What changed: The list of changes moved from the Constitution page to this page of its own, and we dropped the version numbers: the Constitution is now named by the date at the top of its page. The entries from 17 October on show only their date, two entries that named a version now name its date, and the 1 October entry about Article XIX now names the Constitution page; nothing else in the entries changed. Article XIX now points to this page. For anyone citing an old number: 2.0 is 20 September 2026, 2.1 is 17 October 2026, 2.2 is 18 October 2026, 2.3 is 20 October 2026, 2.4 is 24 October 2026, 2.5 is 5 November 2026 and 3.0 is 11 November 2026.
Why: To keep the Constitution itself short and simple to read. Nothing was removed from the history.
