On October 9th, OpenAI's research head stated that after completing an internal investigation, the company has terminated its contracts with three security researchers—Jasmine, Mikita, and Tomek—due to their violations of policies related to handling sensitive information. OpenAI indicated that the issues uncovered in the investigation were more serious than those disclosed by the three in their open letter, leading to the decision to end their employment. The company emphasized that this decision was not based on their concerns about AI safety or the expression of differing opinions, noting that internal security discussions and research debates are a normal part of the company's daily operations. In response to the external oversight issues mentioned by the three in their open letter, OpenAI stated that it is collaborating with third-party security assessment agencies and will release relevant details in the coming weeks. The company believes that ensuring the monitorability of frontier models requires collective efforts across the industry, which is also a core aspect of its research plan.
