Lovable has integrated Claude Opus 4.5 as a core model to enhance planning, design, and accuracy in app development. The model's advanced reasoning capabilities are expected to improve the planning phase significantly, leading to better design outcomes and increased project success rates. Users have reported a 15% reduction in mistakes during edits and a 5% increase in project success. The upgraded model also powers key aspects of code generation, promising immediate improvements without additional costs for Lovable users. The accessibility and power of chat mode and code generation remain unchanged, offering a seamless integration of next-generation reasoning into the development process.
