This Agent implements Exa's example project https://docs.exa.ai/examples/recent-news-summarizer as a simple example of what you can build with Exa.ai. In this example, we will build an LLM-based news summarizer with the Exa API to keep us up-to-date with the latest news on a given topic. We will use Exa to retrieve recent news articles and then feed the article contents to GPT4o for summarization. This is a form of Retrieval Augmented Generation (RAG).
