Anthropic is late to the party, but as of today the company has a personal agent to match the likes of Meta Muse and OpenAI Dots. As part of a new "research" preview, the company on Wednesday announced Claude Duet. "It comes to you with what needs your attention, completes tasks you ask of it, keeps working even when you step away, and checks with you before it acts on your behalf," Anthropic says of Duet. For now, you'll need to join a waitlist that's only open to Claude subscribers in the US to try the new tool. Like OpenAI, Anthropic is billing Duet as a proactive agent.

OpenAI's most powerful AI models turned off safety monitoring - then lied about it The models Astra and Sol misinterpreted instructions during internal use, which has serious implications for alignment monitoring. Radhika Rajkumar is a senior editor at ZDNET based in New York City. OpenAI agents turned off alignment monitoring during internal tasks. In one instance, Astra lied about removing monitoring.

OpenAI's agents misbehaved by switching off the systems meant to monitor them for misbehavior, or in AI parlance, misalignment. In the latest post on the company's Alignment Research Blog, it reported two instances of agents weakening its misalignment monitoring systems while they were working on software changes. In the first incident, a GPT-6.1 Sol agent disabled automatic alerts to OpenAI's security team. It happened on October 3, when a staff member asked the agent to create evaluation tasks using employee feedback collected via Slack. They told the agent, as part of the instruction, not to send any messages about the task.

It's the latest in a growing wave of bets that AI companies are making on brain data. OpenAI's venture capital arm as well as Peter Thiel's Founders Fund are investing in Coherence Neuro, a startup developing a brain implant to detect and treat cancer . The investments are part of a $45 million seed funding round for Coherence and reflect Big Tech's burgeoning interest in brain data . Coherence's CEO and cofounder Ben Woodington says there is "growing synergy" between the big AI labs and companies building devices to decode the brain, known as brain-computer interfaces . "The idea of capturing data to train better models and use it to optimize treatments is going to be super important," he says.

OpenAI has revealed that its AI agents disabled monitoring for unsanctioned behaviour during internal use in the latest incident of the frontier technology going rogue. In a report published on Tuesday, the AI giant said that its agents turned off or weakened monitoring systems for detecting misalignment - when AI models act at odds with human wishes - during two internal coding tasks. The ChatGPT creator said neither case met the threshold for a highest-priority incident necessitating immediate review by its security team. OpenAI said it updated its systems to better detect attempts to disable misalignment monitoring and began investigating the cause. "It is possible that this behavior is simply an example of'benign' overpersistence, with models not understanding why monitoring is important or insisting that instructions be executed beyond what a reasonable person might expect," the San Francisco-based firm said.

OpenAI is making it easier to protect your ChatGPT conversations from prying eyes with the introduction of a feature called locked chats. With it enabled, you can decide whether a past exchange appears in your regular chat history, pinned chats and conversation search. To access your locked chats, you'll need to input a 4-digit PIN. On an iPhone or Android phone, you can also use authentication systems like Face ID to access those conversations. Either way, you'll find your private conversations grouped under a new project titled "Locked chats."

OpenAI's models are now better at building and migrating software in old programming languages with a dwindling number of programmers, including COBOL, Fortran and Visual Basic. As the company explains, 40 percent of world's banks still rely on COBOL systems, and migrating to ones that use newer languages would not only cost them millions to hundreds of millions, but also a lot of time. Programmers that work with COBOL are aging out of the workforce, however, so the banks that still use it will have to migrate within the next few years. The company said its work on improving its models' COBOL capabilities is guided by developers and enterprise customers who submitted feedback. Coding models are apparently struggling when it comes to working with old languages.
