Vertex AI RAG Engine: A developers tool- Google Developers Blog

Introduces Vertex AI RAG Engine, a managed orchestration service for building grounded generative AI applications. It simplifies data retrieval and LLM integration, offering ease of use, customization options (parsing, chunking, annotation, embedding, vector storage, open-source models), high-quality Google components, and flexible integration with vector databases like Pinecone, Weaviate, or Vertex AI Vector Search. It positions RAG Engine as a balance between Vertex AI Search (fully managed) and fully DIY RAG approaches. Provides use cases in financial services, healthcare, and legal, along with getting started resources (notebooks, documentation, integrations, evaluation framework).
