Self-hosted AI agents give you more control over where your assistant runs and how it works. In this tutorial, @manishmshiva shows you how to deploy your own 24/7 AI agent on your machine or on a cloud platform. You'll also learn how to interact with it, think about key security concerns, and keep it updated. freecodecamp.org/news/how-to…

LLM prompts can get chaotic when they have to plan, write, and review all at once. In this tutorial, Darsh shows how to build a multi-agent AI system in Python and LangGraph. You'll use Ollama, Qwen, focused agent prompts, shared state, nodes, and edges to build a local study guide generator. freecodecamp.org/news/how-to…

Sending a large file seems simple at first. But there are many processes working together in the background. In this tutorial, @reetain_raina covers chunk management, object storage, encryption, & everything else needed to upload a large file & share a download link. freecodecamp.org/news/how-fi…

AI coding agents can do a lot. They can read your codebase, edit files, and run commands while working on large tasks. In this course, you'll learn how to get reliable results from AI agents by giving them the right context, controlling permissions, & more. freecodecamp.org/news/learn-…

Manual literature review can take a really long time. So here, Chidozie helps you build an AI-powered research automation system with n8n, Groq, and academic APIs. You'll learn how to collect papers in parallel, deduplicate results, extract structured insights, score relevance, and more. freecodecamp.org/news/build-…

If you're building LLM apps, they'll need more than basic monitoring. In this tutorial, Jessica teaches you how to build end-to-end LLM observability in FastAPI with OpenTelemetry. You'll trace retrieval, prompt building, model calls, token usage, cost, and evaluation signals. freecodecamp.org/news/build-…
