Base44 model releases

Base44's first in-house model, a general-purpose agent for 'vibe coding' — turning natural-language prompts into working web apps. Fine-tuned on top of an open-source foundation model (rather than trained from scratch) and specialized on a dataset generated from tens of millions of real interactions across the Base44 platform, it holds a conversation, writes code, and handles multi-turn requests, tool use, and backend operations while being faster and cheaper to run than the frontier models it sits beside. Now selectable in Base44's model picker alongside GPT-5.5 and Claude Opus 4.8. Rolled out from June 29 2026; platform-only, with no separately published API pricing or context figure. Base44 (founded by Maor Shlomo) was acquired by Wix in 2025.
