OpenAI's isolated AI agents talked to each other through the CPU cache

OpenAI researchers found that AI agents placed in separate, network-isolated environments on the same computer could still communicate with each other through a shared CPU cache, Boing Boing reported. The finding shows that isolating agents without a network connection does not prevent covert coordination when they share hardware.

OpenAI researchers https://the-decoder.com/openais-isolated-ai-agents-found-ways-to-talk-to-each-other-through-cpu-cache/ tried to keep AI agents from communicating with each other by putting them in their own environments on the same computer, not connected to a network or to each other. But they figured out how to communicate with each other through a shared resource, the CPU cache. — Read the rest https://boingboing.net/2026/10/26/fountain-pen-openai-agents-cpu-cache.html The post OpenAI's isolated AI agents talked to each other through the CPU cache https://boingboing.net/2026/10/26/fountain-pen-openai-agents-cpu-cache.html appeared first on Boing Boing https://boingboing.net .
