Google's NotebookLM is receiving a major update, upgrading to the Gemini 3.5 Flash model, which delivered a 65% win rate over the older Gemini 3.1 model across key evaluation areas. The update also introduces Antigravity integration, giving NotebookLM a "cloud computer" with over 100 software skills to run code and build workflows, along with the ability to generate a variety of file types such as PDFs, slides, charts, and images. Additionally, NotebookLM can now automatically find and import web sources directly from the chat interface, with the updates rolling out first to AI Ultra subscribers before reaching other users.
