Amazon vs. Perplexity – U.S. Court of Appeals for the Ninth Circuit

Amazon.com Services, LLC filed suit against Perplexity AI, Inc., an artificial intelligence company, asserting that Perplexity’s web browser tool, Comet, unlawfully accessed Amazon’s website in violation of the federal Computer Fraud and Abuse Act (CFAA) and California’s Comprehensive Computer Data Access and Fraud Act (CDAFA). Perplexity’s Comet browser includes an AI “Assistant” that, when activated by a user, navigates Amazon.com on the user’s behalf, sending browser screenshots to Perplexity’s servers for further instruction. Amazon claimed that this use of the Assistant, despite their explicit prohibition, amounted to unauthorized access to its servers.

How my e-reader lost its stripes

I’ve been a lifelong reader, which has proved a fragile habit in our era of endless trivial distraction. While books and e-ink readers solve the problem of competition for attention, they can’t compete with a phone for convenience. That tiny device in my pocket has made reading both easier and more vulnerable to displacement whenever a notification pops up. A few days ago, I learned for the first time about a recent generation of tiny e-ink readers. Since they’re cheap, it was easy to give into curiosity: I bought an Xteink X3. Not only is it astonishingly tiny, I could immediately install the delightful open-source CrossPoint firmware. I was very quickly able to install a few books. I also appreciated being able to install custom fonts, th

Why don't machine learning research agents overfit?

New research shows that AI agents — like human research communities — learn strategies compressible enough to fit in a few tokens, which prevents memorization and explains why benchmark-driven ML keeps producing real progress.

Cua (YC P25) Is Hiring a Founding Technical GTM Lead

uploaded image About Cua Cua is building the infrastructure and agent products that let AI safely and reliably use computers and applications. At the center of our ecosystem is Cua Driver, the fastest-growing computer-use framework. Developers use Cua Driver to build agents that operate browsers, native applications, and complete desktop workflows across macOS, Windows, and Linux. We also provide the infrastructure needed to develop, evaluate, train, and operate these agents at scale: fleets of real computer environments, agent evaluation tooling, and verified trajectory data. Cua is backed by Y Combinator. We're a small technical team building foundational infrastructure for the next generation of AI agents. The Role We're looking
