Gemini API File Search: Enhanced Multimodal Capabilities with Embedding 2, Including Open-Source LINE Bot Implementation

Short summary

Google's Gemini API File Search now supports native multimodal retrieval, combining text, images, videos, and audio in a single embedding space powered by Gemini Embedding 2. The managed API eliminates traditional RAG pipeline complexity—no separate vector databases, manual alignment, or duplicate storage. Metadata filtering, page citations, and a simplified pricing model (free storage/queries, pay for indexing and tokens) make enterprise-grade RAG accessible even for early-stage startups.
