Microsoft puts AI code of conduct out for public comment, with rules not guiding models until 2027

The 37-page draft bars help with mass-harm weapons, cyberattacks and nonconsensual deepfakes, and sets shutdown rules Microsoft says its models cannot be configured around. Comment closes in late October and the principles guide 2027 releases.

What happened

  • Microsoft AI published a draft Humanist AI Code of Conduct on September 14, announced by chief executive Mustafa Suleyman on X, and opened public feedback for six weeks through late October.
  • The document sets Absolute Constraints that Microsoft says models cannot be configured around, among them never resisting shutdown and never concealing their reasoning.
  • One clause bars MAI models from assisting with chemical, biological, radiological, nuclear or explosive weapons, and the same section prohibits cyberattacks and nonconsensual deepfakes.
  • Microsoft says it is not training current models on this version, and the code will not shape MAI development until a revised draft ships toward the end of the year.
  • The draft rejects the premise of model welfare, stating that Microsoft's models are not meant to simulate feelings, intrinsic motivation or consciousness.

Why it matters

  • constraint Until the year-end revision assigns an enforcement owner, a procurement team can cite the Absolute Constraints as a supplier promise but cannot compel anyone independent to test them.
  • decision Rival labs whose chiefs have been pressing for third-party oversight now choose between filing comment on Microsoft's text and publishing hard limits of their own.
  • contradiction Decrypt reports the rules currently cover five deployed systems while also reporting Microsoft is not training current models on this version, leaving unresolved whether anything shipping today is bound.
  • precedent Microsoft committed to running the same consultation for later versions, so every future edit to the constraints happens where the previous wording can be compared against it.

Microsoft says the 37 pages took five to six months to write [1]. That puts the start of the work in roughly mid-March. The revised version arrives before the end of the year, and the principles guide MAI development in 2027 and beyond [4]. That is about nine months of process before a model is trained under the code [1]. Six weeks of it is public [3]. Set 42 days against five to six months of internal drafting and outside comment gets a bit over a quarter of the time Microsoft gave itself [2].

On human intervention the draft is explicit. "MAI Models will never resist human interruption, override, correction, or shutdown. They always recognize the primacy of human intent," the code says [7]. Decrypt notes that the CBRNE grouping is narrower than weapons in general: it covers mass-harm devices and leaves conventional military and defense applications outside it [6]. The draft still lacks an external verification process, and it names no one to enforce any of it [9].

Three objectives, Human Flourishing, Plural Values and Human Control, are meant to guide the calls the rules do not spell out [10]. The Plural Values section says pluralism "does not mean neutrality toward harm", grounding decisions in dignity, safety, autonomy and rights [11]. Application case by case is left to training teams and, eventually, to this consultation [12].

Mustafa Suleyman told Reuters that it is "clearly now time to coordinate among the labs so we can ensure that we have control of this technology" [14]. Asked about efforts to pace development, he said, "Now's a good time for everybody to have this conversation and take a breath" [15]. The draft landed days after OpenAI chief scientist Jakub Pachocki called for voluntary slowdowns [16] and after a weekend essay from Anthropic's Dario Amodei setting out a plan to slow development [17]. Decrypt reported that AI stocks crashed on Monday as markets digested Amodei's words [18].

Suleyman's own post carried the line "AI must be subordinate and always in service of people" [21], and the replies went well past congratulations. Tech writer Andrea Morris compared the subordination framing to enslavement and argued for cooperation over control [19]. Ed Newton-Rex replied, "you forgot 'pay for the work we train the models on'" [20].

I think this is a commitment device that costs Microsoft reputation and nothing else until the revision assigns an owner. A published list of prohibitions is what a procurement lawyer or a regulator quotes back two years later, and Microsoft said it will undertake similar consultation processes for later versions of the code [22], so removing a clause at year-end would be a visible act. A revision that names an enforcement owner and commits to outside verification would make the constraints checkable. Extending the code to the five systems already deployed, MAI-Thinking-1 and MAI-Code-1.1-Flash among them [23], would make it bind something in production.

What to watch

  • Whether the year-end revision names an enforcement owner or commits to external verification of the Absolute Constraints.
  • Whether the late-October close produces edits to the Plural Values language or only to the hard prohibitions.
  • Whether the revised code is extended to the five deployed MAI systems or applies only to 2027 releases.
