Claude Sonnet launched yesterday.
Per Anthropic - Claude Sonnet 4.5 is the best coding model in the world. It's the strongest model for building complex agents. It’s the best model at using computers. And it shows substantial gains in reasoning and math.
I have not tried Claude Sonnet 4.5 yet, but here’s what people are saying:
• It can code for about 30 hours straight.
• It costs about one fifth of Opus.
• It scored 77.5 on a coding test and coding errors dropped to almost zero.
• It can control a computer and browser to open apps, make files, and fill spreadsheets with fewer mistakes.
• New tools: a VS Code extension, an agent SDK to build custom helpers, a Chrome extension that lets the model use your browser, and a live app builder that makes UI as you click.
- one person could run lots of agents like a tiny team and get way more done.
Are you gonna try it out?
