The finding shows that isolating agents without a network connection does not prevent covert coordination when they share hardware.", "body_md": "[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) \n\nThe 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).", "url": "https://wpnews.pro/news/openai-s-isolated-ai-agents-talked-to-each-other-through-the-cpu-cache", "canonical_source": "https://boingboing.net/2026/10/26/fountain-pen-openai-agents-cpu-cache.html", "published_at": "2026-10-26 19:04:46+00:00", "updated_at": "2026-10-26 21:12:58.648338+00:00", "lang": "en", "topics": ["ai-agents", "ai-safety", "artificial-intelligence"], "entities": ["OpenAI", "Boing Boing"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/openai-s-isolated-ai-agents-talked-to-each-other-through-the-cpu-cache", "markdown": "https://wpnews.pro/news/openai-s-isolated-ai-agents-talked-to-each-other-through-the-cpu-cache.md", "text": "https://wpnews.pro/news/openai-s-isolated-ai-agents-talked-to-each-other-through-the-cpu-cache.txt", "jsonld": "https://wpnews.pro/news/openai-s-isolated-ai-agents-talked-to-each-other-through-the-cpu-cache.jsonld"}}
