Base44, a San Francisco-based vibe coding startup, announced on Monday that it had trained and released its own large language model called Base 1 to combat the generic look of AI-coded websites. Users can now select Base 1 from a selection of AI models, including Claude's Opus 4.8, Fable 5, and OpenAI's GPT-5.5. CEO Maor Shlomo told Business Insider that the company developed its own model because the problem with using frontier models for making websites is that "everybody feels like they're getting the same UI when they're coding with the general models." Base44 was acquired by Wix last June for $80 million, and Shlomo said Wix has a large team of designers generating data for the model to train on. The Base44 team will conduct "reinforcement learning" on the new model, prompting it to keep generating designs that look new and unique. While Base 1 is "not yet there," Shlomo aims for it to "create something that looks uniquely different" each time it generates a user interface. He said the team started working on Base 1 about six months ago, with breakthroughs in the last few weeks allowing an earlier release.
