According to God of Prompt on Twitter, the Opus 4.6 AI model demonstrated its advanced full-stack capabilities by building a complete SaaS landing page—including authentication, Stripe payment integration, and email workflows—in just 47 minutes. The AI was prompted to create a production-grade page with modern frontend technologies like React 18, TypeScript, Tailwind CSS, and Framer Motion, as well as backend integrations such as NextAuth.js for authentication, Stripe for payments, and ConvertKit for email management. This development highlights significant business opportunities for rapid web application prototyping and deployment, especially for startups and SaaS companies seeking to accelerate their go-to-market strategy, according to the original Twitter post.
