Recently, the
developer community leaked information that Google is working on a built-in model selector for NotebookLM, providing a drop-down menu in the interface that allows users to switch between different models such as Gemini Flash and Pro, in order to make trade-offs between responsiveness and output quality depending on the task. The description shows that this feature is still in the testing stage and is not yet generally available in the official version of NotebookLM.
Based on the available revelations, the model selector is expected to appear in NotebookLM's main interaction area, integrating with the current conversation and knowledge base features. Users can choose the default fast Flash model when working on scenarios such as long document organization, study notes, or report generation, or switch to the Pro model when they need higher inference quality and performance on complex tasks. Google has not publicly stated when the feature will be officially launched, nor has it been clarified whether it will only be available to paid or enterprise users, and the specific permissions and billing methods are still to be confirmed.
