Gemini 3.5 and Antigravity come to Google NotebookLM
NotebookLM gets Gemini 3.5 and Antigravity, initially limited to AI Ultra and enterprise accounts.
Google is upgrading NotebookLM with Gemini 3.5 and Antigravity, pushing the product beyond source-based Q&A into more agentic research workflows. The update adds a secure cloud computer for each notebook, enabling code execution, deeper analysis, and richer file outputs. For now, availability is limited to AI Ultra and enterprise customers, with broader rollout planned later.
Google is rolling out a significant wave of upgrades for NotebookLM, and Ars Technica's report focuses on the introduction of Gemini 3.5 and Antigravity — currently only available to Google AI Ultra and enterprise account users. This means NotebookLM is no longer simply organizing user-provided documents into summaries, Q&A sessions, or Audio Overviews, but is moving closer to an agentic tool capable of assisting with research, analysis, and deliverable production.
