Gemini API adds multimodal File Search features
According to Google’s May 05, 2026 blog post, the Gemini API‘s File Search tool now supports multimodal retrieval, custom metadata filters, and page-level citations. The update, the blog states, uses Gemini Embedding 2 to process images and text together to improve contextual search over visual and textual assets. Per Google’s earlier product announcement on Nov 06, 2025, the File Search tool is a fully managed RAG service; that post also says storage and embedding generation at query time are free and initial indexing is charged at $0.15 per 1 million tokens using gemini-embedding-001.
