Base44 trains its own model for vibe coding

TechCrunch reports that Base44, the vibe-coding platform Wix bought for $80 million, is rolling out its own model called Base1. The company says the model was trained on tens of millions of real user interactions from its app-building platform, giving it a more specialized feedback loop than a general frontier model. Founder Maor Shlomo frames the move as a way to improve latency, cost, efficiency, and long-term margins while making Base44 less dependent on outside model providers. The article also notes the competitive pressure from Lovable, Cursor, Claude Code, and frontier labs moving into app creation.
