OpenAI backs a shared robots.txt signal for training preferences

Focus: Applied Generative AI for Knowledge Workers

Topics: Training preferences, Robots policy, Publisher controls
Evidence: Publisher Authored
Availability: Available

Current provider-specific crawler rules are separated from a planned shared training-preference signal; implementation timing and the lack of universal enforcement remain explicit.

Summary: OpenAI says it will honor a shared robots.txt signal for websites that want to express preferences about foundation-model training. The company will keep its existing specific crawler controls and participate in IETF standardization. Implementation is planned over coming months, so publishers should treat the announcement as a future policy commitment, not current enforcement.

Why it matters: Website owners can document today’s crawler rules, identify the new shared preference when specifications stabilize, and verify server logs after rollout instead of assuming one declaration already changes every provider’s collection behavior.
