Anthropic

OpenAI says it is pausing "internal activities" around an in-development AI model, Astra, because it doesn't yet meet new security standards the company is putting in place. The announcement follows its recent disclosure that OpenAI models accidentally hacked Hugging Face. Anthropic and Meta have also since admitted that they had AI models that went rogue and breached other organizations. Recent internal evaluations of an OpenAI model called Astra indicate that it offers "significant advancements in agentic coding and cybersecurity," according to the company. "These results, in addition to ex...

Some of the biggest names on Google's AI team got new jobs this week. In some cases, including for legendary Googler Jeff Dean, those jobs are no longer at Google. Given that Google's models seem to be behind the best of what's coming out of anthropic and OpenAI, is this a sign of Google in turmoil? Is it about Demis Hassabis wanting something more interesting to work on than virtual assistants? Or is there something else entirely happening here? On this episode of The Vergecast, Nilay and David start by discussing the leadership shake-up at Google, the state of the AI race, and whether Googl...

Historian Jill Lepore has a theory about why tech companies often use soaring language to describe their products — almost as if they’re forming a new government. And whether you’re thinking of Twitter’s old “town hall in your pocket” or Anthropic’s Claude constitution, it’s a theory that doesn’t paint Silicon Valley in a very flattering light. In Lepore’s upcoming book, The Rise and Fall of the Artificial State, the Pulitzer […]
