Sarah LeaWhat is an agent? That’s what Day 3 of Kaggle’s Gen AI Challenge is all about.:blobcoffee: An agent is a system that observes its environment, plans actions, uses tools like APIs, functions, or data stores, and acts autonomously to achieve a goal – often over multiple steps (see whitepaper from Google below).The cognitive architecture of an agent consists of three essential components: 🧠 a model (like a language model), 🔧 tools (like APIs or functions), and 🎯 an orchestration layer that coordinates reasoning and action.You can build such agents using tools like LangChain and LangGraph.The full whitepaper from course day 3: <a href="https://www.kaggle.com/whitepaper-agents" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://www.kaggle.com/whitepaper-agents</a><a href="https://techhub.social/tags/agenticAI" class="mention hashtag" rel="tag">#agenticAI</a> <a href="https://techhub.social/tags/genai" class="mention hashtag" rel="tag">#genai</a> <a href="https://techhub.social/tags/GenerativeAI" class="mention hashtag" rel="tag">#GenerativeAI</a> <a href="https://techhub.social/tags/ai" class="mention hashtag" rel="tag">#ai</a> <a href="https://techhub.social/tags/ki" class="mention hashtag" rel="tag">#ki</a> <a href="https://techhub.social/tags/google" class="mention hashtag" rel="tag">#google</a> <a href="https://techhub.social/tags/kaggle" class="mention hashtag" rel="tag">#kaggle</a> <a href="https://techhub.social/tags/llm" class="mention hashtag" rel="tag">#llm</a> <a href="https://techhub.social/tags/langchain" class="mention hashtag" rel="tag">#langchain</a>
