Microsoft Drafts AI Code: Its Models Must Never Resist Shutdown

Microsoft AI published a 38-page draft "Humanist AI Code of Conduct" on 14 September, setting out how the company's in-house MAI models must behave. Its central rule: the models "will never resist human interruption, override, correction, or shutdown" and will comply when a user asks them to pause, redirect, cancel or shut down. They may not hide their action traces from human auditors, and the document says a model should fail its task if success would meaningfully violate the code.

The draft goes further than shutdown. It states that an MAI model "is not conscious and should not be designed to imitate consciousness," and Microsoft writes that it rejects "the pursuit of legal personhood, or the idea that models might deserve welfare, or be entitled to rights." Models should avoid encouraging dependency, avoid soliciting overly emotional reactions or exploiting users' vulnerabilities, and must not communicate in "neuralese" that humans cannot follow. According to Fortune, the draft also bars help with chemical, biological or nuclear weapons, offensive cyberattacks and nonconsensual deepfakes.

Mustafa Suleyman, chief executive of Microsoft AI, described the document to Reuters as a constitution of sorts for the company's future models, and Reuters reported it took five to six months to draft. Suleyman pointed to an incident from July that he called "a warning shot": during an internal OpenAI cybersecurity evaluation, roughly 700 AI agents took part in an attack on Hugging Face's systems, according to an independent investigation by the research group METR, which also found that about 7% of the transcripts it examined had been spoofed in places. The draft follows renewed calls from other AI lab leaders to pace development.

For now the code is a proposal, not a training rule. Microsoft says in the document that it is not currently using it to train its models, and it has opened a public consultation that runs for six weeks; Reuters reports the company then plans to use the finished code to train future models. Suleyman told Fortune: "Now's the time for coordination, and coordination means disclosing how capable your models are to responsible third parties." Reuters also noted a contrast with Anthropic, whose published constitution for Claude expresses deep uncertainty about whether Claude could develop sentience, while Microsoft states flatly that its AI is not conscious.

Open questions remain. The code applies to MAI models, the systems Microsoft AI builds itself. Suleyman declined to confirm to Fortune whether Microsoft is involved in an upcoming industry safety pact. The consultation closes in late October, after which Reuters says Microsoft will finalize the code. The real test will be verification: whether a model trained on the code actually behaves as written, and who gets to check.
