Conversation context can degrade in very long threads, sometimes causing the model to forget earlier instructions or details discussed many messages ago.

Limited to Google's supported document formats, with no direct integration for citation managers like Zotero or Mendeley that researchers commonly rely on.
Audio Overview generation can take several minutes for large document sets, and the conversational format occasionally oversimplifies nuanced technical content.
