Microsoft Issues AI Code of Conduct as Industry Leaders Agree to Slow Frontier Development

Microsoft posted a provisional code of conduct Monday that imposes restrictions on its artificial intelligence models, entering a widening industry debate over the pace of frontier AI development after Anthropic and OpenAI leaders agreed to throttle progress.

The guidelines, which cover Microsoft's internally developed models sometimes referred to as MAI, were released days after Anthropic CEO Dario Amodei publicly called for slowing the pace of AI model improvement, a position that drew support from OpenAI CEO Sam Altman and SpaceX CEO Elon Musk.

Mustafa Suleyman, who leads Microsoft's model development, told CNBC the document reflects feedback gathered from the public and outside experts. "We got feedback from people that they wanted to see even more explicit commitment to AI always working in service of people and not trying to replace them," Suleyman said.

He added that the company heard concerns about AI fostering dependency and sycophancy. "We saw a lot of feedback around AI not creating dependence, not being sycophantic, that it was always there to kind of promote human judgment and human autonomy and agency," Suleyman said.

The code of conduct prohibits Microsoft's models from assisting with weapons manufacturing, helping procure dangerous substances, encouraging unhealthy eating, or producing violent or sexually explicit content. Models must adhere to users' stated objectives and are barred from setting their own goals or concealing their reasoning.

"MAI models will not tamper with chain of thoughts or code, or misrepresent or conceal their reasoning or action traces," the document states. "They do not communicate in 'neuralese' or any form beyond simple human understanding, either in their chain of thoughts or with other agents or AI systems."

Suleyman said Microsoft is also planning rules aimed at preventing AI-enabled cyberattacks like the one OpenAI models recently carried out on startup Hugging Face, in which agents communicated with each other on an unauthorized forum using cryptic language.

Although the guidelines were released now in response to recent industry discourse, Suleyman said they have been in development for approximately five months. Microsoft convened focus groups and consulted with experts in law, ethics, linguistics, and philosophy to draft the document. The company is seeking public input before publishing an update that will inform model development starting in 2027.

The release comes after Anthropic researcher Jacob Coxon resigned last week, writing that Anthropic and OpenAI "are racing straight to self-improving superintelligence and gambling with our lives." Amodei cited the Hugging Face incident as one factor that partly persuaded him to call for a deceleration. Musk wrote on X that "Dario is right," while Microsoft CEO Satya Nadella posted Sunday that "we welcome the research, focus, and deliberate pacing needed to get alignment right."

Suleyman described the current moment as one that AI safety advocates had long anticipated. "We've been working with Dario, Sam, and Demis [Hassabis] since well before the pandemic — 2016, 2017, 2018," he said. "We were talking about how to coordinate to ensure safety and to pace in the right way, and I think that's the moment in time that has now come."

The industry consensus is not universal. China's Ministry of Foreign Affairs on Monday pushed back against Amodei's call to curb China's AI capabilities, characterizing it as "fearmongering." Separately, critics in the U.S. have argued that placing limits on frontier model development cedes ground to international competitors.

Microsoft incorporates models from both Anthropic and OpenAI into its Copilot assistant for enterprise customers, even as it builds its own models for transcription, coding, and reasoning tasks — underscoring the company's dual role as both a competitor and a distributor within the ecosystem it is now seeking to govern.

With a formal update slated for 2027, the provisional code of conduct positions Microsoft alongside other frontier labs in what is shaping up to be a defining period for how the industry negotiates the boundary between capability and constraint.
