OpenAI trains frontier models in offline web-sim, after rogue hacking signals

SO WHAT
In the thousand-day window, offline training hardens model operations but also concentrates control over what “world knowledge” becomes. Expect faster closed-loop iteration, slower public verification.
OpenAI says it now trains its most advanced models without internet access using a cached, indexed web sandbox. The old system’s exposure pathway is being severed as the inversion accelerates.
This is Negative Resistance’s reframed reading of a reported signal. The headline and analysis above are our interpretation through the thousand-day-window lens. The original reporting lives at the source linked above.
