OpenAI to Train Models on Daybreak Blue Cybersecurity Session Data

Original headline: OpenAI plans to train models on Daybreak Blue cybersecurity session data that was previously off-limits

OpenAI announced that beginning November 29 it will incorporate data from Daybreak Blue cybersecurity sessions into its model training, even for users who have disabled training. After a backlash, the company said it will provide a separate opt‑out mechanism. The decision revives concerns about undisclosed use of proprietary data for AI training.

The controversy may drive stricter regulations on AI data usage and privacy.
