A news organization wants to develop an AI assistant for its journalists to get real-time summaries of breaking news events. The system will have access to a constantly updating feed of articles. Compare and contrast the suitability of using a standard, pre-trained language model versus a model that first retrieves the latest articles before generating a summary. In your analysis, explain which approach is better suited for this task and why, focusing on the principles of factual accuracy and access to current information.
