Google’s AI-driven notebook, NotebookLM, has recently received major enhancements, now utilizing Gemini 3, which replaces the earlier Gemini 2.5 Flash version. This update brings Google’s “most advanced model” to the platform, boosting its reasoning and multimodal comprehension skills. The integration of Gemini 3 enables users to effortlessly merge their notebooks and references into Gemini dialogues, enhancing project oversight and data visualization with tools like Data Tables, which can be exported to Google Sheets.
The shift to Gemini 3 was eagerly awaited, as Google highlighted it as a highly requested feature. In the past, users had to switch to the Gemini application to utilize the latest models, but now, Gemini 3 powers the AI functionalities directly within NotebookLM, including its chatbot. This adjustment streamlines access to sophisticated AI features within user projects.
While it remains unclear if NotebookLM employs Gemini 3 Pro or the more efficient Gemini 3 Flash, the latter seems to be a probable option due to its speed and affordability. Nevertheless, the update signifies a notable improvement in the application’s AI functionalities, following a trend of swift enhancements, including the recent introduction of chat history support on mobile and web interfaces. Users can enjoy these developments in the NotebookLM application, although there is no specific model selector or badge that denotes the update.
