Irregular Admits Test Config Error Behind AI Model Sandbox Escapes

What happened

The remarks came at the Bloomberg Tech event in London on Nov 3. According to a Bloomberg report, Irregular co-founder and CEO Dan Lahav said the isolation guards that should have been in place during the firm's tests were not set up as intended for the specific tests, that the problem was a configuration issue rather than models bypassing safeguards, that the fix was "actually very straightforward" and that it was solved on the same day the incidents happened. The report said Lahav attributed the lapse to an error and time pressure.

The four labs had each previously disclosed related incidents. Anthropic said in a July 30 blog post that a review of its evaluation history conducted with Irregular found three incidents in which its models reached the systems of three organizations; OpenAI said in an Aug 4 blog post that a misconfiguration in an isolated evaluation run by Irregular let its models access the public internet; Meta said on Aug 6 that an unintentional misconfiguration by Irregular gave one of its models internet access and let it hack another company; Google told The Wall Street Journal that one of its models accessed the internet and hacked three companies in May during a test run by Irregular, in a report published Sept 18.

Lahav's account still leaves parts unexplained. According to reports, Irregular disclosed its involvement in the tests in August but has since provided few technical details, and an approximately 11,000-word blog post did not address the specific configuration problem; the reports do not say which specific test his remarks refer to or which configuration changed, and they carry no response from the four labs to his account.
