OpenAI, Google, Microsoft and Anthropic announced their intention to adopt a new standard that would allow publishers to prohibit the use of their materials for training AI, according to The Verge AI, citing information previously published by Search Engine Roundtable.

The proposed common signal should give publishers the ability to apply their preferences to multiple companies at once, rather than configuring them separately. The initiative is linked to a proposal by Kevin Kelley, Chief Standards Technologist in Anthropic, within the Internet Engineering Task Force.

Practical significance depends on whether the standard is formally adopted and uniformly implemented by participants. The material provided does not include details on the signal format, timelines for implementation, or enforcement mechanism.
