Build a Chess AI That Thinks Like a Human — A Beginner-Friendly Guide with ChatGPT
March 23, 2026 · Emily Henderson · 3 min read
What if your chess app didn’t try to calculate every possible move like old-school engines, but instead played more like a human—using intuition, simple plans, and a bit of “thinking”? The good news is: with today’s tools like ChatGPT and open-source libraries, even a high school student can build a chess AI that feels intelligent without needing massive computing power or years of research.
Which regex turns plain-text URLs into clickable HTML links?
March 21, 2026 · Nina Kimes · 3 min read
Turning plain-text links into clickable HTML anchors is one of those tasks that looks simple until you run into punctuation, parentheses, query strings, and edge cases like already-linked URLs. Regex can help a lot, but the “best” pattern depends on what you consider a valid URL, what inputs you expect, and how safe you need the output to be.
Why Are GPUs Still the Top Choice for AI Training Over NPUs?
March 20, 2026 · Dustin Collins · 3 min read
AI training is mostly a story of moving and multiplying huge matrices, again and again, across weeks of iteration and constant model changes. In that world, GPUs continue to win mindshare and budgets even as NPUs (neural processing units) improve quickly. The reason isn’t that NPUs are “bad” or that GPUs are “perfect”; it’s that training demands a mix of flexibility, mature software, memory scale, and predictable performance across many model types—areas where GPUs have built a long lead.
Can You Train an AI Stock Trader on Historical Market Data?
March 19, 2026 · Lillian Kim · 3 min read
Training an AI stock trader on historical market data is possible, and people do it every day in research labs, hedge funds, and personal projects—but “possible” is not the same as “profitable” or “reliable.” Historical prices, volumes, order book snapshots, and related indicators can teach models to detect patterns and make predictions or trading decisions. The real question is whether those learned patterns will hold up when the market changes, costs are applied, and risk is measured in real money.
Why Is It So Hard for AI to Search and Find the Right Number in Excel?
March 18, 2026 · Katherine Holland · 3 min read
If you've ever asked an AI assistant to look up a value in your spreadsheet and gotten back a confidently wrong answer, you're not imagining things — and it's not a random glitch. AI feels dumb with Excel because, under the hood, it is not doing cell-by-cell lookup the way Excel does. Instead, it is doing fuzzy pattern matching over text, which is great for language but terrible for finding exact numbers in specific rows and columns. That fundamental mismatch is exactly why AI keeps mixing and matching data that you, as a human, can see is obviously separate.
How AI Coding Solves Real Problems
March 17, 2026 · Lillian Kim · 5 min read
Large language models are often treated like writing assistants, but one of their most useful abilities is coding. When you ask AI to write code that produces a result, you move beyond getting a one-time answer and start building a tool that can solve the same problem again and again. That is what makes AI coding so practical. Many everyday tasks are not just writing tasks. They are formatting tasks, data tasks, automation tasks, and workflow tasks. Instead of asking AI to only “help,” you can ask it to build the thing that does the work.
How Should You Chunk Documents for AI?
March 14, 2026 · Lillian Kim · 3 min read
Document chunking sounds simple until you try to build it for a real AI system. Split text too aggressively and the model loses context. Make chunks too large and retrieval gets noisy, slow, and expensive. Good chunking sits in the middle: small enough to keep results precise, large enough to preserve meaning. If you want better search, cleaner summaries, and stronger question answering, chunking deserves careful thought from the start.
What Does a Machine Learning Algorithm Look Like?
March 13, 2026 · Jessy Chan · 3 min read
If you are new to machine learning, it is normal to picture something mysterious: long code, hard math, and strange symbols on a whiteboard. The truth is much simpler. A machine learning algorithm often looks like a pattern finder. Sometimes it can be written as a short math formula. Sometimes it looks more like a list of rules or steps. In many cases, it is both: a formula plus a method for adjusting the numbers inside that formula until the predictions get better.
Why Does LLM Reasoning Cost So Many Tokens?
March 12, 2026 · Billy Ewing · 3 min read
When people first hear that a language model can “reason,” they often picture a quick burst of thought followed by an answer. The reality is less dramatic and more mechanical: reasoning usually means the model generates, tests, revises, and extends many pieces of text before it reaches a response. Since tokens are the basic units used to process both the prompt and the reply, every extra step adds cost. What feels like a single answer to a person can involve a long internal path for the model, and that path is what drives token usage up.
How do you search keywords in a database?
March 11, 2026 · Alicia Gopin · 3 min read
Keyword search is one of the most common tasks in software: finding rows where a word or phrase appears in a text field. It sounds simple, but the “right” method depends on your database, the size of your data, and what kind of matching you need (exact, partial, case-insensitive, multi-word, ranked results, and so on). This article walks through practical ways to implement keyword search, with tips that keep queries accurate and performant.
What does a modern pre-training data pipeline look like?
March 10, 2026 · Jessy Chan · 3 min read
Pre-training looks less like “download the internet and train” and more like an industrial process: many stages that progressively turn noisy web-scale text into a shaped mixture of tokens that matches a training plan. Modern pipelines spend serious effort on deduplication, filtering, and curriculum-style mixing because model quality depends on what you feed it, not just how much you feed it.
FlowRL: Teaching AI to Think in More Ways Than One
March 9, 2026 · Ben Larson · 3 min read
Imagine you're studying for a math test and you only ever practice one type of problem. When the real test comes and the questions look slightly different, you're stuck. That's exactly the problem that FlowRL — a new way to train AI — was built to solve.
What Is OpenClaw?
March 8, 2026 · Annie Hayes · 3 min read
OpenClaw is an open-source AI assistant that runs on your own machine and works through chat apps you already use, including WhatsApp, Telegram, Discord, Slack, Teams, Signal, and iMessage. It is designed as a personal agent platform, which means it does more than answer prompts: it can remember context, connect to tools, browse the web, work with files, and carry out actions on a computer.
What are the downsides of using iframes on a website?
March 7, 2026 · Emily Henderson · 3 min read
Iframes can feel like a convenient shortcut: drop a snippet into your page and instantly show a map, a video, a form, or even a whole external page. That simplicity is real, and in some cases it’s the right choice. Still, iframes come with tradeoffs that affect performance, security, accessibility, SEO, maintenance, and the overall polish of a site.
How to Make AI Search Your Website Knowledge Efficiently?
March 6, 2026 · Alicia Gopin · 3 min read
Many small and medium-sized businesses run WordPress websites that already contain valuable knowledge—help center articles, FAQs, service descriptions, and documentation. When adding an AI assistant to answer customer questions, the key challenge is allowing the AI to access that knowledge quickly and reliably without constantly loading live webpages.
What Are MCP Servers and Clients?
March 5, 2026 · Ben Larson · 3 min read
Modern AI applications often need to interact with real systems—databases, APIs, documents, and developer tools. But before MCP existed, integrating these systems with AI was messy and repetitive. Every AI product had to build its own custom connectors to every tool, which meant the same integrations were constantly being rebuilt in slightly different ways. As developers started building more AI assistants and agents, this fragmentation became a serious bottleneck. The Model Context Protocol (MCP) was introduced to solve this problem by providing a standardized way for AI systems to connect to external tools and data sources.
How Can You Build a Simple Neural Network on a MacBook?
March 4, 2026 · Dustin Collins · 3 min read
Building a simple neural network on a MacBook is a practical way to learn the basics of machine learning without special hardware. With the right Python setup and a small project, you can train a model that recognizes patterns in data in under an hour, while also learning the core workflow: prepare data, define a model, train it, and evaluate results.
Who Owns AI-generated Artwork?
March 3, 2026 · Alicia Gopin · 3 min read
AI-generated artwork raises a deceptively simple question: if a model was trained on millions of images made by other people, who—if anyone—owns what the model produces? The answer depends on a mix of copyright rules, contract terms, and how the artwork was created and used. It also depends on which country’s law applies, because copyright is not identical worldwide.
How do AI models build long-term memory across sessions?
March 2, 2026 · Alicia Gopin · 3 min read
Chatbots feel most helpful when they pick up where you left off: your preferences, your ongoing project, the tone you like, and the details you already shared. Traditional AI conversations reset when the session ends, but newer systems are moving toward “long-term memory” that persists across days or weeks. This shift isn’t about giving a model a human mind; it’s about engineering reliable ways to store, retrieve, and use prior context without causing privacy problems or compounding mistakes.
How can AI help evaluate job applicants?
March 2, 2026 · Annie Hayes · 3 min read
Hiring teams are flooded with resumes, screening calls, interview notes, and feedback forms, yet still struggle to predict who will perform well and stay. AI can help HR move faster and make decisions more consistent—if it’s used as a structured assistant rather than an automated judge. Below are practical, “start this week” ways to use AI in applicant evaluation, with clear guardrails to keep the process fair and defensible.
Can We Shrink Billion-Parameter Models Without Losing Intelligence?
February 28, 2026 · Ben Larson · 3 min read
Billion-parameter models feel like the peak of modern AI: fluent, versatile, and surprisingly capable across many tasks. Yet their size brings costs—latency, energy use, memory pressure, and deployment friction. The big question is whether “intelligence” is inseparable from sheer parameter count, or whether we can compress these models while keeping most of what makes them useful.
Will Serious LLMs Ever Run Fully On-device?
February 27, 2026 · Emily Henderson · 3 min read
For years, the default way to use large language models has been to send prompts to a remote server and wait for an answer, but that pattern is starting to look less fixed than it once did. Chips are getting better, models are getting smaller and more efficient, and consumer devices now ship with dedicated AI accelerators. The real question isn’t whether on-device LLMs are possible—it’s what “serious” means for consumers, and which trade-offs people will accept.
What Is an NPU? A Simple Guide to the AI Processor in Modern Devices
February 26, 2026 · Jessy Chan · 3 min read
You’ve probably started seeing laptops and phones advertised as “AI PCs” or “AI-ready devices.” The reason isn’t just software — it’s a new chip inside them called the NPU (Neural Processing Unit). Unlike a CPU that runs programs or a GPU that handles graphics, an NPU is designed specifically to run artificial intelligence directly on your device. It enables live translation, video call background blur, smart photo search, voice assistants, and even offline AI writing tools — all without sending your data to the cloud.
What Is Batch Processing When Using Large Language Models (LLMs)?
February 25, 2026 · Aria Singh · 3 min read
Large Language Models (LLMs) like GPT-style systems have unlocked powerful capabilities — summarization, classification, coding, search, document analysis, and conversational agents. But once you move beyond a single prompt and start building real applications, you quickly run into a practical reality: you rarely need the model once. You often need it hundreds, thousands, or millions of times. That is where batch processing comes in. Instead of sending requests one-by-one in real time, batch processing groups many LLM tasks together and runs them as a scheduled or bulk job. This changes how you design systems, manage cost, and scale AI workflows.
