## What is the Gemini File Search Tool and how does it function as a managed RAG solution?

## Overview The Gemini File Search Tool is a fully managed Retrieval-Augmented Generation (RAG) system integrated directly into the Gemini API. ## Key Features The API response contains grounding_metadata with citations for provenance. ## Technical Specifications Pricing: file storage and query-time embedding generation are free, with charges of $0.15 per 1 million tokens for indexing. ## How It Works Users create a File Search Store, upload raw files, and the tool automatically handles chunking, embedding, and indexing. ## Use Cases ## Limitations and Requirements It offers less granular control over chunking strategies compared to custom builds and lacks hybrid search. ## Comparison to Alternatives The primary advantage is its contrast with custom RAG stacks requiring multiple disparate components. ## Summary In conclusion, the Gemini File Search Tool is a managed RAG solution that significantly lowers the barrier to entry.
