Wix-owned Base44 launches proprietary AI model for vibe coding platform
Tags AI · OSS · Enterprise
Base44, the Wix-owned vibe coding platform, has begun rolling out its own proprietary AI model with the goal of eventually outperforming frontier models on coding tasks. The move represents a broader trend among AI application-layer startups seeking defensibility by reducing dependence on third-party model providers. Base44 allows users to build applications through natural language descriptions, and the company believes a purpose-built model will offer better performance for its specific use case. The platform launched its commercial service in September 2025 and has seen rapid adoption since.
Technical significance
Base44's decision to build its own model reflects a strategic calculation that vertical-specific AI models can outperform general-purpose frontier models on narrow tasks. This mirrors the broader industry trend where application-layer companies seek to reduce API costs and latency while improving task-specific performance. For developers, it signals that the AI coding tool market is entering a phase where differentiation comes from model quality rather than UX alone.
