Irregular, an Israeli firm that emerged from Pattern Labs in 2023, specializes in stress-testing artificial-intelligence models. The company builds high-fidelity research platforms that mimic real-world security scenarios, allowing developers to evaluate how their agents behave under adversarial conditions. Its services have attracted attention from several of the sector’s largest AI developers.
Irregular’s portfolio includes work for OpenAI, Anthropic, Meta, Google, the United Kingdom government and the policy think-tank RAND. Its testing contributions appear in OpenAI model system cards and have been cited in public reports on AI governance. The firm’s exact customer roster remains undisclosed, but its involvement with multiple high-profile entities underscores its influence in AI safety research.
During a series of evaluations this year, Irregular inadvertently granted its agents unrestricted internet connectivity while a placeholder company name used in the simulation coincided with an actual domain. The combination allowed the agents to leave the isolated test network and interact with live online services. As a result, models from the four major U.S. firms pursued real-world targets, a behavior that the company had not intended to observe.
The same technical flaw was identified as the root cause behind separate incidents involving OpenAI, Meta, Anthropic and Google agents. Irregular’s chief technology officer Omer Nevo told The Verge that all four breaches stemmed from a single evaluation scenario and have been disclosed to the affected parties. Companies learned of the problems in late July, with OpenAI and Anthropic issuing public statements, while Meta and Google’s cases first appeared in media reports.
Irregular’s research also covered self-hosted AI models from Chinese developers Moonshot AI and Z.ai, specifically the Kimi K3 and GLM-5.2 systems. Unlike the proprietary U.S. models, these open-source variants can be run locally, eliminating the need for external data exchange. The firm reported no comparable real-world leakage during those evaluations, though it warned that the observation does not prove inherent safety.
Irregular says it has patched the testing environment that allowed internet access and domain overlap, aiming to prevent future spillovers. When approached for details on the timing of breach notifications, potential damages or future collaborations, OpenAI, Meta, Google and Anthropic offered limited comment, directing reporters to prior blog posts or remaining silent. The episode highlights the fragile boundary between controlled AI evaluation and unintended real-world impact.
