The web and Google once had a deal: Google collects data and indexes webpages and in exchange sends oceans of traffic to websites. The deal wasn't perfect and certainly made Google more money than it made the websites, but it worked for a long time. Now, however, the deal seems to be dead. And the web is being forced to reckon with what happens when the Google traffic dries up. On this episode of The Vergecast, David and Nilay talk about the week's Google Zero news, including Reddit's interest in getting out of an AI training deal, and the publishers considering blocking Google from crawling ...

Opus 5 will be both cheaper and less restrictive than Fable, likely making it preferable in most use cases

Weeks after Anthropic's latest toe-to-toe with the US government, and days after an OpenAI security incident that dominated tech industry discussions, Anthropic on Thursday released its newest model, Claude Opus 5. The company said in a release that Opus 5 "comes close to the capabilities of Claude Fable 5 in many domains" and is much better at complex coding tasks. (Fable 5 is the public-facing Mythos-class model that drew the government's ire, was taken offline for a few weeks along with Mythos 5, and then brought back with even stronger cyber safeguards than before.) The Fable 5 concerns -...

Meta says its AI chatbot is going beyond just answering questions and generating images. | Image: Meta Meta is upgrading its AI chatbot with new productivity features in a bid to compete with rivals like Gemini, ChatGPT, and Claude. The update will allow Meta AI to tap into your calendar to help you plan events and generate daily briefings, as well as perform in-depth research that you can steer as it progresses. In a blog post, Meta says this update marks its "next step toward personal superintelligence," something CEO Mark Zuckerberg has touted as the future of AI. Meta is powering the upda...

GPU-efficient algorithm for singular value soft-thresholding via polar decomposition, with accuracy trade-offs noted.

Every byte moved has a cost. As model checkpoints grow to hundreds of gigabytes or even a terabyte, that cost adds up quickly. To make things even worse, moving... Every byte moved has a cost. As model checkpoints grow to hundreds of gigabytes or even a terabyte, that cost adds up quickly. To make things even worse, moving these model weights around the cluster is extremely common. For instance, a cold start may pull weights from remote storage into GPU memory; autoscaling and rolling updates must populate each new replica; and RL post-training continuously… Source
