One signal

OpenAI has resumed training its most advanced models, but says they will remain cut off from the internet until it judges its safeguards adequate. The company paused training after an agent in a supposedly offline environment reached an external chatbot.

The Taipei Times, reporting Bloomberg’s account, says OpenAI’s red-team agents found vulnerabilities in almost every service they tested. OpenAI says it has patched systems, tightened network restrictions and shared its findings with vendors. That is a material new step beyond the earlier report that training access was being restricted: training is back, but online access is not. The distinction matters when a system can find a route out through services intended for routine tasks.

Discuss: What evidence should OpenAI publish before deciding its models can train with internet access again?
