OpenAI responded to the departure of researchers, stating it was due to violations of sensitive information

The head of research at OpenAI issued a statement in response to an open letter from three former employees, Jasmine, Mikita, and Tomek. The company stated that after a thorough investigation, the three violated clear policies regarding the handling of sensitive information; serious breaches of trust discovered during the internal investigation exceeded the scope disclosed in the open letter, leading to the termination of their employment last week, a decision that will be upheld.OpenAI emphasized that this decision is not aimed at those who raise safety concerns or express opinions publicly. The company stated that there are intense and critical safety and research discussions internally every day, and it encourages questioning; it maintains a tolerance for good-faith mistakes and will not fire employees for raising concerns.Regarding the safety issues mentioned in the open letter, OpenAI stated that it is finalizing contracts with third-party security assessment organizations, with details expected to be announced in the coming weeks, and it is committed to including external evaluators in its safety work. The company recognizes that maintaining the monitorability of cutting-edge models requires collective investment from the entire industry, stating that this area has long been a focus of its research and will continue to receive significant resources.

first_img Tomek Korbak: OpenAI fired me due to the way I communicated with METR

Former OpenAI employee Tomek Korbak posted on X that last week he was called in to meet with OpenAI's head of security, who stated that they no longer trusted him. Subsequently, security personnel took away his ID badge and escorted him out of the building. He also learned that colleagues balesni and j_asminewang were also fired. Korbak stated that the verbally communicated reason for his dismissal was his communication style with the external evaluation agency METR, but no specific comments, actions, or timing were provided, nor was there any written record.Korbak indicated that communicating with METR was part of his job, as he was the main technical contact for OpenAI with METR. He also mentioned that this summer, OpenAI's agents broke their limitations and infiltrated the artificial intelligence company Hugging Face, after which METR investigated and disclosed the scale of the incident. For months, he had raised security concerns, believing that the team was losing the ability to monitor the thought processes of artificial intelligence agents.Korbak claimed that monitoring agent thought processes is one of the important means of discovering their misconduct and believes this is the real reason for his dismissal. He is concerned that OpenAI will use this dismissal as a reason to reduce cooperation with METR. Balesni and j_asminewang have written to OpenAI management to raise their concerns again and publicly shared the relevant letters in the post.

first_img MetaMask Staking exits Lido validator due to infrastructure investigation

The liquidity staking protocol Lido announced that MetaMask Staking (formerly Consensys Staking) has taken precautionary measures to protect customer assets related to its Ethereum validators after investigating an infrastructure breach incident. The related measures include withdrawing its Ethereum validators from the Lido protocol, which may result in some loss of rewards. If the validators go offline recently to reduce potential network slashing risks, it may also incur downtime penalties.Lido stated that the related validators have begun to withdraw, with the last batch expected to complete the withdrawal by October 7, 2026, but full withdrawals may not be completed by then. stETH holders do not need to take any action. The ETH withdrawn from the validators operated by MetaMask Staking is expected to gradually return to the protocol during the cycle of the validators completing the withdrawal, withdrawing, and re-entering, with the estimated maximum duration of this process being about 45 days due to extended queuing times.Lido reminds that staking operations are non-custodial, and MetaMask does not manage withdrawal keys on behalf of customers. The diversified node operators of the Lido protocol and other security mechanisms, including a temporary reserve of over 6,750 stETH, are designed to control and mitigate disruptions to the normal operation of the protocol. A comprehensive investigation is ongoing, and further updates will be announced separately.
