Google adds Gemini 3.5 and code execution to NotebookLM

Google has announced a major update to its AI-powered research tool, NotebookLM, introducing advanced reasoning, code execution, and enhanced source discovery capabilities. The changes, announced on June 8, 2026, represent a significant evolution for the tool, which is now powered by the Gemini 3.5 model and a new system called Antigravity.

The update centers on three core improvements. First, every NotebookLM notebook now includes access to a secure cloud-based computer, allowing the AI to write and execute code on a user's behalf. Google states this enables deeper analysis and more sophisticated research workflows by tapping into over 100 curated software skills for tasks like data analysis and visualization.

Second, the tool's export capabilities have been expanded. Users can now generate downloadable outputs in a wider array of formats, including PDFs with charts and tables, Microsoft Word and PowerPoint files, CSV and JSON data files, and image formats like PNG and SVG. Users can provide detailed instructions for these exports and make edits after the files are generated.

Third, the process of starting a research project has been streamlined. Previously, NotebookLM required...
