TLDR: OpenAI is reportedly preparing GPT-5.4 with an extreme reasoning mode and a 1-million-token context window, more than doubling the current limits. This would represent a significant leap in what LLMs can process in a single session, but practical utility at that scale remains an open question.
TLDR: Google NotebookLM now uses Gemini 3 and Veo 3 to generate cinematic video overviews from your uploaded documents, essentially turning your notes and research into narrated visual content. It is an impressive demo of multimodal AI but raises questions about depth versus polish.
