Additionally, you can now customize AI characters to fit your needs.
If you haven’t used NotebookLM yet, it’s even more worth trying now.

NotebookLM adopts the latest Gemini model, comprehensively improving the quality and accuracy of AI responses.
Recently, Google announced on its official blog that NotebookLM has received the latest Gemini model, though it did not specify which version. This latest model supports a full 1 million token context window, allowing it to understand more content while also improving its performance in analyzing multiple data sources, with higher accuracy and better reasoning.
The ability to remember dialogue context has also been extended sixfold, meaning that during long conversations with the AI, you’ll get more coherent and relevant results—something that’s crucial for learning content.
Google said user satisfaction increased by 50% after switching to the latest Gemini model.

Additionally, Google has also strengthened the underlying capabilities of NotebookLM. In simple terms, the AI will now automatically read data from multiple perspectives, identify key points, and then synthesize those findings into a single, more refined response.
This change is a big plus for handling notebooks with large amounts of data, allowing for better identification of key points and background information, thereby providing high-quality, highly reliable answers.
NotebookLM now also automatically saves conversations! This means that after you close the current session, you can continue the conversation in the future without losing any history. Of course, you can also delete the chat history at any time.
In the shared notebook, your chats are only visible to you. The auto-save conversation feature will begin rolling out gradually over the next week.
