In a key product upgrade, Lovable has now announced that it uses Claude Opus 4.5 as one of its core AI models-driving measurable improvements to design quality, reliability, and experience in workflows.
Early performance data shared by the company indicated that the integration of Opus 4.5 resulted in:
15% fewer AI-generated mistakes
A 5% increase in overall project success rates
Clear improvements in visual design, layout consistency, and UX alignment.
Notably, these enhancements come without any extra cost for the already existing Lovable users, marking one of the most impacting platform upgrades that happened this year.
The move underlines Lovable’s commitment to pushing the envelope on vibe coding and AI-assisted product development, granting access to creators and teams alike to more powerful and reliable tools without increasing pricing tiers.
With Opus 4.5 now powering critical parts of the platform, Lovable users are already reporting smoother builds, cleaner UI outputs, and faster iteration cycles.
The company is inviting users to share feedback as the new model continues to roll out across features.
