Base44 unveils its own AI model amid rising startup defensibility race
A fresh wave of AI startups is carving out defensible positions by developing their own models rather than relying solely on third-party providers. The latest to join this trend is Base44, the vibe-coding platform owned by Wix, which has begun rolling out its own AI model with ambitions to eventually surpass today’s leading frontier systems.
The move reflects a broader shift in the industry as companies seek more control over their technology stacks and user experiences. By building an in-house model, Base44 aims to tailor performance and capabilities specifically to its platform’s needs—something that off-the-shelf solutions may not fully deliver. This strategy also reduces dependency on external vendors and could create a moat around its core product offering.
Why companies are building their own models
The push toward proprietary AI isn’t limited to Base44. Across the startup ecosystem, firms are investing in custom models to differentiate their services, improve response quality, and maintain data privacy. For platforms built around generative AI—especially those focused on low-code or “vibe coding”—having a bespoke model can mean faster iteration, better alignment with user workflows, and stronger competitive positioning.
What’s next for Base44
While the rollout has started, the company has not detailed timelines for broader availability or performance benchmarks. If successful, Base44’s model could help solidify its role as a go-to platform for AI-assisted development, while also serving as a case study for other startups considering similar paths. For now, the tech community will watch closely to see how this in-house model performs against established alternatives—and whether it helps Base44 close the gap to frontier-level capabilities.
