OpenAI Fires Three Staffers for Mishandling Sensitive Information

BBC Technology ↗

OpenAI fired three researchers, Jasmine Wang, Tomek Korbak and Mikita Balesni, after an internal probe found they shared confidential details with an outside AI evaluation group. OpenAI says the firings are about unauthorized handling of information and not whistleblowing. Two of the three had publicly voiced AI safety concerns, and Balesni had estimated a greater than 10% chance of AI causing human extinction.

Anthropic to Invest $100 Million to Train AI Engineer Talent

CNBC Technology ↗

Anthropic will spend $100 million to train nearly 10,000 AI engineers by 2027 through a new Claude Frontier Academy, partnering with several consulting firms.

Apple Tightens Full Disk Access on Macs to Curb Abuse From AI Agents

Ars Technica ↗

Apple will add new controls to the macOS Full Disk Access setting, saying some apps use it to reach files, mail, messages and browsing history without users fully understanding. The change targets always-on AI agents such as Meta's Muse and OpenAI's Dots, and granting that access will now require very explicit user action. It follows a report that Muse appeared to read a user's messages, which Meta disputes.

CNBC Technology ↗

Interpol's global chief information security officer Bjorn Watne told CNBC that AI is mostly supercharging familiar crimes like scams and fraud, making them faster, cheaper, more convincing and easier to scale.

Tokyo Court Recognizes Legal Protection for Human Voices in AI Clone Case

TechRepublic ↗

The Tokyo District Court ruled that a person's voice can be protected under publicity rights, in a case brought by Jujutsu Kaisen voice actor Kenjiro Tsuda against a TikTok account that used an AI clone of his voice in more than 180 videos. The judge said the human voice is symbolic of personality, just like a portrait. The deletion request was dismissed because the account had closed, but voice actors see the ruling as a landmark.

Judge Warns AI Could Stunt Lawyers' Training and Harm Their Clients

Wired ↗

Nurses at HCA Healthcare say Timpani, an AI scheduling tool built with Palantir and used at about 130 of its 190 locations, routinely understaffs shifts, ignores their preferences and leaves teams exhausted. At Rayus Radiology, a Palantir-based scheduling tool linked requests to the wrong patients and invented patient details. Staff warn the errors threaten patient safety and are urging hospitals to drop Palantir systems.
