According to @NotebookLM, NotebookLM is now officially part of the Google AI Ultra plan, offering subscribers the highest access to Gemini’s latest models and exclusive AI-powered productivity features. Users benefit from increased feature limits for tools such as Audio & Video Overviews and Slide Decks, the ability to include more sources per notebook, and priority access to advanced features including the reintroduction of the Long option for Slide Decks and the removal of watermarks from Slide Decks and Infographics (source: @NotebookLM, Dec 11, 2025). This move is poised to enhance business workflows and support enterprise adoption of cutting-edge AI collaboration tools, presenting new market opportunities in generative AI productivity solutions.

According to Jeff Dean (@JeffDean), speaking at the Stanford AI Club, recent years have seen transformative advances in deep learning, culminating in the development of Google's Gemini models. Dean highlighted how innovations such as transformer architectures, scalable neural networks, and improved training techniques have driven major progress in AI capabilities over the past 15 years. He emphasized that Gemini models integrate these breakthroughs, enabling more robust multimodal AI applications. Dean also addressed the need for continued research into responsible AI deployment and business opportunities in sectors like healthcare, finance, and education. These developments present significant market potential for organizations leveraging next-generation AI systems (Source: @JeffDean via Stanford AI Club Speaker Series, x.com/stanfordaiclub/status/1988840282381590943).
