Google, Microsoft and OpenAI plan to honor a shared AI training opt-out
Google, Microsoft and OpenAI say they plan to honor a shared robots.txt preference that would let site owners express one AI-training opt-out across participating providers. The mechanism comes from an individual IETF draft, not an adopted standard, and none of the three companies currently supports it. Google and Microsoft described different implementation approaches and timelines.
Why it matters: A common AI-training preference could eventually simplify governance across major AI and search ecosystems, while changing how marketers decide whether content may be used for training or grounding. Teams should monitor the draft, review existing Google and Microsoft directives, and avoid treating the proposal as an active standard or immediate control.
