Vercel recently introduced new AI models on v0.dev and its API: v0-1.5-md, v0-1.5-lg, and v0-1.0-md.
The V0 model has been integrated directly into Cursor, delivering stunning UI generation and elevating the immersive coding experience.
Today, they revealed the "compound model architecture" behind the v0 model.
In simple terms, this architecture combines RAG (Retrieval-Augmented Generation) expertise, the reasoning capabilities of state-of-the-art (SOTA) large models, and a custom streaming post-processing model for bug fixes, seamlessly stitched together.
Vercel claims this approach significantly boosts the quality of v0's generated code. Plus, when foundational large models get upgraded, they can quickly swap in the latest ones while keeping the rest of the system stable.
Why did V0 opt for this "compound model architecture" instead of just using an off-the-shelf large model?
Currently, AI models on the market fall into two categories: closed-source large models from major vendors or third-party-hosted open-source models.
