Join me, Nik (https://x.com/CoFoundersNik), as I sit down with AI expert Elizabeth Knopf (https://x.com/leveragedupside) for a deep dive into Anthropic's Claude 4.5 Sonnet—the latest AI breakthrough for entrepreneurs and business automation in 2025.

Watch as Elizabeth demonstrates game-changing features that transform Claude AI from static outputs into dynamic web applications through API integration and parallel tool execution. We explore extended AI thinking capabilities (up to 30 hours of processing), which delivers higher quality outputs for complex business tasks without constant iteration errors or AI hallucinations.

The highlight? Claude generates a 22-page competitive analysis and content strategy for my YouTube channel versus Chris Koerner's "Corner Office"—complete with viral frameworks, audience insights, and growth recommendations. This deep AI research previously required specialized tools like Perplexity AI.

We break down practical AI productivity strategies including building your AI second brain, prompt engineering libraries, context document management, and AI agent development for business operations. Elizabeth shares her framework for mastering AI tools like a fighter pilot—developing true AI literacy beyond basic prompting.
