NotebookLM Gets a Brain Boost: Meet Gemini 2.5 Flash!
Google NotebookLM gets a brain boost with the Gemini 2.5 Flash upgrade. This AI tool, famed for its Audio Overviews, now thinks “deeper” for better research responses. Just don’t expect it to serenade you with improved audio yet—it’s all about text enhancements for now!
