NotebookLM Gains Gemini 3.5 and Antigravity Upgrades for AI Ultra
Google’s NotebookLM is getting a major upgrade to Gemini 3.5 with Antigravity support, expanding file types (PDFs, DOCX, images, CSV/JSON, Excel, slides) and enabling a cloud computer to run code for research workflows, plus a new “research report” source-import flow. The update also adds more than 100 software skills to streamline notebooks and allows generating documents (PDFs, slides) alongside text. The rollout starts today for AI Ultra and Workspace AI Ultra Access/Expanded Access subscribers, with broader availability to other accounts later; Google touts a 65% win rate versus Gemini 3.1 on core metrics like accuracy, multilingual support, large document analysis, document creation, and advanced research.
