From September 29 to October 6, all AI features and usage in published apps are free, powered by Google's Gemini model. This offer applies to Lovable AI, which can be integrated into apps to enable functionalities like chat or image generation without incurring AI inference costs, though normal pricing still applies to Lovable credits. Users are encouraged to take advantage of this opportunity to create AI-native applications such as a Dune Avatar Generator, a ChatGPT clone, or tools to transform blog posts into infographics. The initiative invites users to start new projects and showcase their creations during the free period.
