Summary
NotebookLM’s latest update moves the research app to Gemini 3.5 Flash, adding broader file support, streamlined web-source integration and embedded Antigravity tools.
Google says the Flash model brings faster, more efficient processing, and its side-by-side tests showed NotebookLM on Gemini 3.5 beat the older 3.1 branch in 65% of evaluations.
Antigravity support gives NotebookLM a dedicated cloud computer that can write and run code for research tasks, with more than 100 software skills available for workflow automation.
Launched in 2023, NotebookLM is one of Google’s earliest generative AI products, and the upgrade extends Google’s newer Gemini capabilities into a tool built for document and web analysis.
