Model Context Protocol (MCP) Explained for Beginners
MCP is an open standard for connecting AI applications to tools and data. Instead of writing a custom integration for every assistant, you write one server and any compatible application can use it.

Chain-of-Thought Prompting: Making LLMs Reason
Chain-of-thought prompting asks a model to write out its reasoning before the answer. This guide explains why that helps, measures it on 20 arithmetic word problems with a small open model, counts what the extra tokens cost, and explains why newer reasoning models have made the instruction unnecessary for them.
Ollama Tutorial: Run LLMs Locally on Your Machine
Ollama runs open language models on your own computer with one install. This tutorial walks through the command line, the REST API, conversation history, the OpenAI-compatible endpoint and a custom model built from a Modelfile, all run on an ordinary laptop, with the settings and limits worth knowing.
