One of the most common frustrations when building AI agents is watching them forget everything the moment a conversation ends—or worse, running out of context halfway through a long session. Memory is what separates a toy chatbot from a production-grade agent. In this guide, you will build a two-tier memory system: fast in-memory buffer for recent turns, and a persistent vector store for long-term recall. All code is runnable with Python 3.11+ and the Anthropic SDK. ...

Retrieval-Augmented Generation (RAG) is one of the most practical patterns for building AI agents that work with real-world data. Instead of relying solely on what a language model learned during training, RAG lets your agent pull in fresh, relevant information at query time. The result: fewer hallucinations, up-to-date answers, and responses grounded in your own data. ...

AI-powered scraping agents flip this model: instead of brittle selectors, you describe what you want in plain English, and the agent figures out how to get it. This tutorial builds a web scraping agent that combines Claude’s reasoning capabilities with Playwright’s browser automation. The result is a scraper that adapts to page structure changes and handles JavaScript-heavy sites that traditional scrapers can’t touch. ...

Getting it to run reliably at scale — handling concurrent users, managing costs, surviving traffic spikes, and recovering from failures — is an entirely different engineering problem. This guide walks through a production-grade deployment stack for AI agents using Docker, FastAPI, and AWS. ...

LangChain and LangGraph are often mentioned in the same breath, which makes sense—LangGraph is built on top of LangChain. But treating them as alternatives is a mistake. They solve different problems, and choosing the wrong one for your use case creates real friction. This guide cuts through the confusion. I will show you exactly what each framework is designed for, where each one breaks down, and how to make the decision for your specific project. ...

That works for simple Q&A, but falls apart the moment you need multi-step workflows, conditional branching, or persistent memory across turns. LangGraph solves this by modeling your agent as a directed graph where each node is a processing step and edges determine what happens next. ...

The answer is MCP: the Model Context Protocol. MCP is an open standard that defines how AI models communicate with external tools and data sources. Instead of writing custom integration code every time you want to connect an LLM to a new service, MCP gives you a universal adapter layer. ...

The two dominant choices for building production AI agents in 2026 are OpenAI’s Agents SDK and Anthropic’s Claude API. Both are capable of powering sophisticated agent systems, but they make different design decisions that matter when you are committing to one for a real project. This is a practical comparison based on building agents with both. I will cover the developer experience, tool-calling behavior, safety characteristics, pricing, and the scenarios where each one pulls ahead. ...

Multi-agent prompting is not—and the failure modes are completely different. When agents hand off to each other, a vague instruction that would produce mediocre output from one model can cause catastrophic failures across a pipeline of five. This guide covers the prompt engineering patterns that actually work in production multi-agent systems, with examples drawn from running a real multi-agent orchestration framework. ...

Get it wrong and you rebuild it six months later. Get it right and it disappears into the background—exactly what infrastructure should do. This comparison focuses on the three databases that come up most often in production AI agent systems: Pinecone, Chroma, and Weaviate. I will cover setup, query patterns, performance characteristics, and the scenarios where each one makes sense. ...
