What we know

This shared signal is designed to be recognized by multiple participating AI providers, not just OpenAI, enabling a standardized way for websites to express their AI training content permissions.

Why it matters

As AI models increasingly rely on web data for training, website owners have sought clearer methods to control whether their content is included.

What is still unknown

There is no information on supported languages, enforcement mechanisms, or a timeline for broader implementation. No independent tests of how effectively this system respects website preferences have been reported.
