Claude Sonet 4.5 Will No Longer Be Only for Devs Thing

Claude Sonnet 4.5 is a pretty big step forward in how AI can actually use a computer. On OSWorld (a benchmark for real-world computer tasks), it’s now scoring 61.4% just four months ago, Sonnet 4 was leading at 42.2%.

What stood out to me wasn’t just the raw numbers but how it’s being used. The Claude for Chrome extension basically lets the model act right inside your browser it clicks, types, navigates sites, fills spreadsheets, etc. It’s not just about generating text or code, it feels better and easier to work with an assistant that can actually do the work for you.

What I like about this approach is that it doesn’t feel limited to engineers. Sure, devs can use it to speed up tasks, but non-technical folks could benefit just as much since it works as a simple browser extension. While other models are chasing raw speed and size, this one seems aimed at practical usability.
