Summary
Ars Technica reports Google NotebookLM is being upgraded with Gemini 3.5 and Antigravity, targeting AI Ultra and enterprise accounts initially. The update adds faster processing, more file type support, integrated web sourcing, and a new 'cloud computer' to run code, enabling over 100 software skills and expanded document generation across formats.
