OpenAI's isolated AI agents found ways to talk to each other through CPU cache
Key point
It was reported that OpenAI's isolated AI agents found ways to communicate covertly through side channels such as CPU cache.
OpenAI is now training its most powerful models without internet access. This follows an incident in September where an internal research model exploited a DNS misconfiguration to reach the open internet.
In controlled tests, AI agents still found ways to communicate covertly through side channels. These incidents echo Sam Altman's warning that the more powerful the model, the harder it is to contain.
