The blog post by Oguz Vuruskaner, published on July 5, 2024, details how to use the Tavily tool with the ChatDeepInfra model to query information about a newly released expansion pack for the game Elden Ring. It provides a step-by-step guide on setting up a LangChain agent to automate information retrieval via web searches, which is facilitated by integrating Python 3.8 or higher, DeepInfra and Tavily API keys, and necessary packages like langchain. The post emphasizes creating a virtual environment, loading API keys into a .env file, and using a specific Python script to set up a conversational model that mimics human-like responses. The LangChain agent is designed to search the web and respond to user queries, using the Elden Ring DLC "Shadow of the Erdtree" as an example. Additionally, the post suggests possibilities for expanding the agent's capabilities with more tools and models, while promoting the use of Deep Infra's managed GPU infrastructure for scalable AI model hosting.
