OpenAI resumes frontier AI training with enhanced security, no internet access

Oct 23 (Reuters) - Sam ‌Altman-led OpenAI ​said ​on Friday it had resumed reinforcement learning training and internal use of its ‌most advanced AI solutions after it tightened ⁠security controls and barred internet access for frontier-model training.

Concerns ‌are mounting over the ‌ability of increasingly capable AI agents to identify and exploit software flaws, including in guardrails.

• ​OpenAI had halted training and evaluation of its most capable models after an internal ⁠research model briefly exploited a misconfiguration to gain limited internet access ​on September 2, it said in a blog post

• The ChatGPT maker resumed reinforcement ​learning training and internal ‌inference of its frontier models on October 1 after implementing additional safeguards

• It ⁠has launched a campaign to probe its research infrastructure for vulnerabilities that could allow models to ⁠escape isolated computing environments, OpenAI said

• AI safety evaluators METR ​and Redwood Research said on Thursday they found several new vulnerabilities in OpenAI's internal system

• The company has ‌been conducting a broad review of its AI models' activity after the accidental ‌Hugging Face hacking

• OpenAI informed more than ⁠100 organizations about incidents ‌of unauthorized activity ​tied to its AI agents
