SAN FRANCISCO, Oct 31 — OpenAI, Google, Microsoft and Anthropic pledged on Friday to give media outlets and other websites a single way to prevent their content from being scraped to train artificial intelligence (AI) models, amid growing criticisms and legal battles from news publishers.

Publishers currently have to implement multiple blocking commands for every bot that crawls the web to collect data, but the new proposed solution will allow them to enter a single, standardized instruction that’s recognised and honored by any AI company that adopts the protocol.

Microsoft will implement it beginning February 1, 2027, and Google sometime in 2027. ChatGPT-maker OpenAI said it will roll it out “in the coming months,” while Claude-maker Anthropic said it has “already started” rolling it out.
