Vibe Coding Platform Base44 Launches Own AI Model as AI Startups Seek Defensibility

Base44, the vibe coding platform owned by Wix, has begun rolling out its own proprietary AI model, marking a strategic shift as the low-code/no-code development space seeks differentiation in an increasingly crowded AI landscape. The company hopes its model will eventually surpass current frontier models in performance.

Base44 allows non-technical users to generate applications through natural language descriptions — a paradigm known as "vibe coding." By developing its own model, Base44 is moving beyond reliance on third-party APIs to build its own competitive moat.

This move reflects a broader trend among AI startups: as API costs rise and model capabilities become commoditized, owning proprietary AI is seen as essential for long-term defensibility. TechCrunch first reported the development.

Base44’s strategy follows an industry-wide shift where AI application-layer companies are accelerating their transition from "model integrators" to "model owners," reducing dependence on upstream providers like OpenAI and Anthropic while improving margins.
