## Summary

OpenAI says it now runs frontier model training with no internet access and has built an offline, cached web environment for reinforcement learning. The environment lets models search and communicate with one another, while OpenAI says its containment system holds even if an agent escapes its sandbox. Gizmodo reports that OpenAI has not clarified whether agents are led to believe the environment is the real internet.

## Why it matters

The article links OpenAI's offline training environment to specific agent escape incidents, showing how containment design responds to real failures.
