Vertex AI Grounding Large Language Models
Grounding allows Google’s large Language models to use your specific data to produce more accurate and relevant responses.
Grounding is particularly useful to reduce hallucinations and answer questions based on specific information the model wasn’t trained on. This approach is also called RAG (Retrieval Augmentation Generation).
Implementing a Grounding architecture can take some time. In fact, I have written a dedicated article on how you can implement your own custom grounding solution.
Again, thanks to Google, you can now rely on Google Grounding instead of implementing a custom solution (at least for many standard use cases).
Grounding with Vertex AI
Grounding in Vertex AI is based on Vertex AI Search. Your PaLM model is accessing Vertex AI Search before processing your prompt and receives relevant documents.
