level: business
base44, the vibe coding platform wix bought for $80 million last year, is rolling out its own large language model called base1. the model was trained on tens of millions of real user interactions from the platform. founder maor shlomo says owning the model lets the company optimize latency, cost, and efficiency across its stack. the move comes as ai startups debate whether relying on frontier models from providers like openai or anthropic is sustainable.
the custom model aims to outperform general-purpose frontier models for app creation tasks. shlomo expects other vibe coding platforms with enough scale and data will follow suit. however, competition is growing from ai labs themselves. cursor and grok now belong to spacex, and claude code has entered the vibe coding space. these labs gain data and feedback loops that could improve their models for app building. shlomo argues specialization gives base44 an edge, but investor jonathan userovici warns against underestimating frontier models, citing legal tech startup harvey which dropped plans for its own model.
cost pressure is a key driver. enterprise customers increasingly demand better return on investment and are setting up infrastructure to select cheaper models without sacrificing performance. base44 expects its model to be faster and cheaper than frontier options like claude opus. the company says owning the model will improve margins over time, though upfront costs are high. base44 recently passed $100 million in annual recurring revenue, still behind rival lovable's $500 million. shlomo bets vertical integration—owning distribution, data, and infrastructure—will strengthen its market position.
why it matters: training custom models on proprietary user data could help ai startups reduce inference costs and build defensible products, challenging the dominance of general-purpose frontier models.
