Vercel introduces v0 composite AI models that combine retrieval-augmented generation (RAG), frontier LLMs, and a custom AutoFix model to generate web application code. The architecture addresses limitations of standalone models by providing up-to-date framework knowledge, specialized web development focus, and automatic error correction. The system uses preprocessing with context retrieval, state-of-the-art base models for generation, and a custom-trained AutoFix model that runs 10-40x faster than alternatives while maintaining quality. This modular approach allows upgrading base models without rebuilding the entire pipeline.
