Ars Technica AI·4 hours ago·Release
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.
