Startup Base44 Launched Base1 — Own AI Model for Vibe-Code Application Development

Israeli startup Base44 has launched Base1 — its own AI model trained for vibe coding — and abandoned third-party vendor models on which it built its product for the entire first year of operation.

What is vibe coding at Base44

Base44 is a Tel Aviv-based platform that allows anyone to create a working application simply by describing it in natural language, without writing code manually. This approach in the industry is called vibe coding — generative AI translates a user's text description into a ready-made working product without the involvement of a programmer on the client side.

Why the startup needs its own AI model

For the first year, Base44 built client applications on models from third-party AI laboratories — this is standard practice for most vibe-coding platforms that essentially wrap third-party large language models in a convenient interface. The company explains the transition to its own Base1 model by saying that owning the model is the only way to survive in the rapidly intensifying competition in the vibe-coding market, which The Next Web describes as a gold rush.

• Base44 is a startup from Tel Aviv, Israel
• First year of operation — applications were built on models from third-party developers
• New product — proprietary Base1 model
• Stated reason for transition — control over product quality and economics in conditions of rapidly growing competition

How the company came to its own model

Most vibe-coding platforms today are dependent on the conditions and prices of external model providers — any change in tariffs or limits from a third-party provider directly impacts the platform's own economics. The launch of Base1 changes this dependency: now Base44 controls the entire stack — from code generation to the final application — without an intermediary in the form of someone else's model. This step also gives the company the ability to tune the model more precisely for its own narrow scenario — converting text descriptions into a working application — instead of using a general-purpose universal model trained on a broad spectrum of tasks.

What this means

Base44's transition to its own model is a sign that the vibe-coding market is maturing: startups that previously simply wrapped third-party large language models in a convenient interface are beginning to invest in their own ML infrastructure to avoid dependence on external providers' conditions and prices, and to stand out against dozens of similar competitors fighting for the same market. The Next Web describes what's happening in the market as a gold rush — which means similar announcements about proprietary models from other vibe-coding platforms should be expected in the near future, since dependence on external infrastructure is becoming the main competitive risk for players in this segment.
