Anthropic’s Claude Sonnet 4.5 is available now - ‘the best AI model in the world for real-world agents, coding, and computer use’

Anthropic has just dropped Claude Sonnet 4.5, claiming it’s the top AI model for tackling real-world tasks like coding, building agents, and general computer wrangling, making it a game-changer for tech-savvy SMBs looking to automate grunt work without the hassle. This upgrade brings handy features like checkpoints in Claude Code for easy rollbacks and the ability to whip up files for spreadsheets or docs right in the chat, all included in paid plans to keep your operations humming. With improved behavior that cuts down on sketchy stuff like sycophancy or delusional outputs, Sonnet 4.5 can now handle autonomous tasks for up to 30 hours—far outpacing its predecessor—letting small-business owners free up their teams for bigger creative wins. Early adopters, including folks at Canva, are raving about its smarts on complex jobs, and while we’re skeptical until we test it ourselves, this release could supercharge your MSP toolkit without hiking prices.
