"We really do earnestly believe AI could kill all humans!"

Anthropic researcher Jacob Coxon resigned over AI extinction fears, calling for pacing agreements between labs.

A senior Anthropic safety researcher has said there is more than a 10 percent chance artificial intelligence "could kill all humans" by the end of the decade, just hours after a colleague resigned over fears the AI lab and its rivals are carelessly racing to build "superhuman systems" they cannot control. In a post on X announcing his departure, Jacob Coxon, a researcher who has trained AI systems at Anthropic, said he had quit the company over its lax approach to safety. Coxon, who previously trained systems for OpenAI, accused the two AI companies of "racing straight to self-improving super...

Muse is a "personal AI agent" designed to help out with everyday tasks and projects, like online shopping, sending emails, and planning a trip. Once given a goal, Meta says Muse can work on its own, opening a browser, filling out...

Anthropic says power users are key to its business - it's prioritized them even when it means cutting off other popular applications, like OpenClaw.

In an expanded class-action lawsuit filed today, a group of Claude subscribers say the company deceptively advertised the limits of its Max subscription tier. The lawsuit was brought by attorneys Monica Vaca and Kati Daffan, who both formerly worked at the Federal Trade Commission under Lina Khan. It's a ...

On Thursday, a judge ruled that the Pentagon's blacklisting of Anthropic earlier this year was unconstitutional, delivering the AI lab a win in a monthslong rollercoaster of a battle with the Trump administration. The lawsuit, filed in March in a California district court, accused the Trump administration of unlawfully retaliating against Anthropic for setting "red lines," or unacceptable military use cases of its AI technology.
