Grounding connects Gemini to real-time data sources so it can give accurate, up-to-date answers instead of relying only on training data.

Grounding Options

• Google Search grounding: Gemini searches the web in real time before answering
• Vertex AI Search grounding: Connects to your private enterprise data
• Custom data sources: Ground responses in your own documents via RAG

Why It Matters

Grounding dramatically reduces hallucinations and ensures answers are current — critical for business applications.
