During my first week at Zone01 Kisumu, I worked on a project called go-reloaded . It was my first real hands-on experience using Go, and it helped me understand not just the language, but also how to think like a developer. In this article, I’ll share what I learned, the challenges I faced, and the key concepts that made everything click. What the Project Was About The goal of the project was to build a small Go program that works with command-line arguments and processes input using Go’s standard libraries. This was my first time interacting deeply with: os package command-line arguments (os.Args) basic Go program structure At first, it felt confusing, but step by step, things started to make sense. What I Learned How command-line arguments work in Go I learned that Go provides access to raw input from the terminal using: os.Args This returns a slice of strings where: os.Args[0] is the program name os.Args[1:] are the actual inputs Working with the os package The os package became one of the most important parts of the project. I used it to: Read input arguments Handle program execution flow Understand how programs interact with the system This helped me realize that Go is very close to the system level compared to JavaScript. Breaking problems into smaller steps One of the biggest lessons wasn’t about code—it was about thinking. Instead of trying to solve everything at once, I learned to: Understand the problem first Break it into smaller tasks Solve each part step by step This made debugging much easier. Challenges I Faced At the beginning, I struggled with: Understanding how os.Args works Knowing where to start in the code Handling errors when inputs were missing Sometimes I would get stuck just trying to figure out what the program was actually receiving. But debugging helped me a lot. Printing values at each step made things clearer. Key Takeaways Go is very explicit compared to JavaScript The os package is powerful for system-level interaction Command-line ar

vibe citing: how KPMG used AI to write a report about AI and AI made them look like fools by t474-r0b07 There are companies that charge you to tell you how to use AI responsibly. KPMG is one of them. 250,000 employees. 138 countries. Decades advising governments and corporations on how to avoid costly mistakes. In October 2025 they published a report titled "Total Experience: Redefining Excellence in the Age of Agentic AI" . They wrote it with AI. The AI invented 88% of the sources. Nobody verified anything. They published it anyway. // what is "agentic AI" — because the title matters An agentic AI is not a chatbot. Not the assistant that answers your questions. It's a system that makes decisions and executes actions on its own, without a human approving each step. You give it an objective and it acts, corrects, moves forward. It's the product everyone in the tech sector was selling in 2025. KPMG was selling it too. That's why they needed a report proving their clients were already using it. Spoiler: they weren't. And the report invented it anyway. // the forensic analysis GPTZero — a company specialized in detecting AI-generated content — ran a full audit on the report. First: what is an AI hallucination, because the term is going to come up a lot. When a language model doesn't have the information you ask for, it doesn't say "I don't know." It generates a response that sounds correct. It invents with the same confidence it would use if it actually knew the truth. Perfect format. False content. No warning. That's a hallucination. Now the numbers from the KPMG report: TOTAL CITATIONS: 45 REAL CITATIONS: 5 INVENTED CITATIONS: 40 ACCURACY RATE: 11.1% 40 of 45 citations have invented titles, authors that don't exist, or sources that don't say what KPMG claimed they said. Half of the factual claims in the report are false or misattributed. A firm that charges for intellectual rigor published a document with 11% accuracy. // the organizations that read the report and sai

How I Cut Costs 65% Migrating LangChain to DeepSeek I want to tell you about a switch I made recently that genuinely surprised me. If you're running LangChain in production and haven't explored the DeepSeek models yet, this one's for you. Let me show you what I learned, what broke, and what I'll never go back to. The short version? I was burning cash on a generic LLM setup. I migrated to DeepSeek through Global API's unified interface, and my monthly inference bill dropped by over 60%. Setup took me less time than brewing coffee. Let me walk you through it. Why I Even Looked at This in the First Place Here's the thing about working in AI engineering: the model landscape moves so fast that whatever you chose six months ago is probably overpriced now. That's been my experience, anyway. When I first built my LangChain pipeline, I defaulted to a popular name-brand model because, well, that's what everyone was using. It worked. It was fine. Then I looked at my AWS bill. That's when I started digging into alternatives. And let me tell you, the rabbit hole is deep. Global API alone exposes 184 AI models at prices ranging from $0.01 to $3.50 per million tokens. That's a wild spread. The trick is finding the sweet spot where cost meets quality, and for migration workloads (think: code translation, schema conversion, content rewrites), I found it with DeepSeek. Let me show you the numbers that actually mattered to me. The Pricing Reality Nobody Talks About I built a comparison table when I was making this decision, and I want to share it because staring at these numbers side by side is what convinced me. Here's the lineup I evaluated through Global API: DeepSeek V4 Flash sits at $0.27 per million input tokens and $1.10 per million output tokens, with a 128K context window. That's my default for most production traffic now. Fast, cheap, and smart enough for almost everything. DeepSeek V4 Pro comes in at $0.55 input and $2.20 output with a beefier 200K context. I use this when

The most important design decision in an email classifier isn't the model — it's the label set, and here's the one I keep coming back to: You triage email into one of four categories: URGENT — production incidents, executive requests; reply within 1 hour ACTION — code reviews, meeting follow-ups; reply same day FYI — informational, no response needed NOISE — newsletters, marketing, automated notifications From: {sender} Subject: {subject} Snippet: {snippet} Return ONLY the category name. Nothing else. That's the working prompt from the Nylas email triage recipe , and almost every line encodes a taxonomy-design lesson worth unpacking. Most people building email agents obsess over model choice and prompt phrasing. The recipe's quiet thesis is that the label set itself does the heavy lifting — get the taxonomy right and a cheap model classifies well; get it wrong and no model saves you. Why four is the magic number The recipe states it flatly: four is the right number. Three loses fidelity — everything important collapses into one overloaded bucket and you've built a binary classifier with extra steps. Five and the model starts confusing categories, because the boundaries between adjacent labels get too thin to express in a definition. Notice what makes these four work. They aren't topics — they're response obligations . URGENT means "reply within the hour," ACTION means "reply today," FYI means "no response needed," NOISE means "archive." Each label maps to exactly one behavior. That's the test I'd apply to any email taxonomy: if two labels lead to the same action, merge them; if one label leads to two different actions depending on content, split it. The same principle shows up in the sales context. The Agent Accounts overview describes an outreach agent classifying replies as interested / not now / unsubscribe — three labels, because the workflow has exactly three branches: book the meeting, schedule a follow-up, stop emailing. The taxonomy is the decision tree, fla

This article presents a straightforward approach to automatically and efficiently tune hyperparameters for machine learning models using Optuna as the optimisation framework. We explore how to use both Optuna’s native storage options and InterSystems IRIS as a database backend to track the progress of hyperparameter searches. We also show how MLflow can be used to monitor experiments and manage models through its tracking and model registry UI. This article is based on this Kaggle Notebook , which you can run and directly edit yourself. When training ML models, the choice of hyperparameters can strongly influence performance. They are not the only factor, but they can significantly affect both convergence and generalisation. Tuning hyperparameters manually takes a lot of effort. This is especially true because hyperparameters interact with each other, so tuning them independently is usually not enough. For example, higher regularisation may require a lower learning rate for more stable optimization. A more complex model may require stronger regularization to avoid overfitting, but at the same time, a very small learning rate on a complex model can make learning too slow. Optuna is an MIT-licensed open source library, which allows commercial use, that automates hyperparameter search for ML models developed with the most popular frameworks such as scikit-learn, PyTorch, TensorFlow, and LightGBM. It works by defining a search space and an objective metric to either minimize or maximize. Optuna then explores the search space efficiently to find well-performing configurations. Here we use Optuna to tune a LightGBM model on a dummy dataset and show how to scale the search using shared database storage. We will also use MLflow for experiment tracking and model registry, and IRIS DB as a possible Optuna storage backend for concurrent studies. We will use the California Housing dataset, commonly used in ML examples, to populate IRIS tables and run the tuning workflow. Note:

There's a line usually pinned on the Roman philosopher Seneca: luck is what happens when preparation meets opportunity. People put it all over social media and like most things on social media, it gets repeated so often that it stops meaning anything. So let me try to make it mean something again, with a math equation and a football match that happened recently at the latest FIFA World Cup 2026. The equation nobody writes down We talk about luck like it's a single mysterious force, either you have it or you don't. But it's not one thing. It's two things multiplied together: Luck = Preparation × Opportunities Look at what that multiplication does. If your preparation is zero, it doesn't matter how many opportunities show up, zero times anything is still zero. And if you're the most prepared person alive but you never put yourself in front of a single opportunity, same result. Zero. The lucky people aren't the ones who got more luck handed to them. They're the ones who kept both numbers high. They got good and they kept showing up to the table where things happen. Hold that thought. Let's go to Texas. Japan, the Netherlands, and the 88th minute On June 14th, 2026, Japan played the Netherlands in their World Cup group opener in Arlington, Texas. On paper it was a mismatch in the most literal, physical sense. The Netherlands are tall . Van Dijk, Van de Ven, the whole spine of that team is built like a row of wardrobes. Japan are one of the shorter sides in world football, quick, technical, but not the people you'd bet on to win a header. If you were designing a contest specifically to humiliate the Japanese, you'd make it about jumping. And for most of the night, the script ran exactly as the bodies predicted. The Dutch dominated the run of play, around 60% possession, more passes, more touches in the box, the better expected goals. Van Dijk, a defender, rose for a cross and headed the Netherlands ahead. Later Summerville restored their lead. The Oranje even won the aer

Every day, startups rent expensive GPUs to power AI applications. The problem is that most of those GPUs spend a surprising amount of time doing nothing. Imagine renting an apartment and only using one room while paying for the entire building. That's effectively what many AI teams do with GPU infrastructure. The Hidden Cost of GPU Rentals When you rent a GPU, you're usually paying for uptime. Whether your application is processing requests or sitting idle at 3 AM, the bill keeps running. For many early-stage products: Traffic is inconsistent Usage spikes are unpredictable Most requests arrive in short bursts As a result, GPU utilization can be far lower than expected. The Utilization Problem A startup might rent a GPU for an entire month. But how much of that compute is actually being used? During development: Developers test occasionally Demos happen a few times a day Customer requests arrive sporadically The GPU remains available 24/7, but actual inference workloads often occupy only a small fraction of that time. Yet the infrastructure bill reflects full-time usage. Why This Matters For startups, infrastructure costs directly affect runway. Every dollar spent on idle compute is a dollar that cannot be spent on: Product development Customer acquisition Hiring Experiments Reducing wasted infrastructure spend can significantly improve efficiency. A Different Model Instead of paying for GPU uptime, what if developers only paid when inference actually occurred? For example: Pay per token generated Pay per image generated Pay per second of video generated This approach aligns cost with actual usage rather than reserved capacity. The Future of AI Infrastructure As AI adoption grows, efficiency becomes increasingly important. The next generation of AI infrastructure may look less like traditional server rentals and more like utilities: Use what you need. Pay for what you use. Nothing more. What has your experience been with GPU utilization and AI infrastructure costs? I

Is FAANG Becoming MANGO in the AI Era? For years, FAANG was the gold standard for innovation and engineering excellence. If you were a developer, working at companies like Facebook (Meta), Apple, Amazon, Netflix, or Google was often seen as the ultimate career goal. But the AI revolution is changing the conversation. Today, some of the most influential companies aren't just building products—they're building intelligence. The spotlight is increasingly shifting toward AI-native organizations such as OpenAI , Anthropic , NVIDIA , and others that are shaping the future of software. The Bigger Shift This isn't really about replacing FAANG with another acronym. It's about a fundamental shift in technology: Search → Answers Automation → Agents Software → Intelligence Features → Capabilities As developers, we're entering an era where understanding AI is becoming as important as understanding frameworks, databases, and system design. What This Means for Engineers The most valuable engineers of the next decade will likely combine: Strong software engineering fundamentals AI-assisted development skills Prompt engineering LLM and agent integration AI-powered product thinking The goal isn't to compete with AI. The goal is to learn how to build with it. Read the Full Article This post was inspired by a thought-provoking article that explores the FAANG-to-MANGO idea in much greater detail. 👉 Read the complete article here: https://www.saurabhsharma.dev/blogs/mangos-vs-faang-ai-era/ What do you think? Are we witnessing the rise of a new generation of AI-first companies, or will traditional tech giants continue to lead the next wave of innovation?

Not every failure is permanent. This is something I didn't think about before. When something fails in my app, my first thought was something broke, fix it. But when I started learning how distributed systems actually work, I realized that some failures are not really failures. They're just temporary. Network glitch. API timeout. A service that just restarted. Rate limiting kicking in. These are all failures but they last for a very short time window. If your system tries the same operation again after a few seconds, it will probably succeed. So the question is does your system know how to try again? Or does it just give up the first time something goes wrong? That's what retry is. What Retry Actually Does Without a retry system, if a temporary failure happens that's it. The entire operation fails. The user sees an error. The request is gone. With retry, your system automatically attempts the operation again after a failure. The goal is simple recover from temporary failures without the user even knowing something went wrong. This felt obvious to me once I understood it. But building it properly is where it gets interesting. The Configuration: What Each Part Controls When I looked into how retry systems are actually configured, there were more options than I expected. And each one exists for a specific reason. maxAttempts — this defines the maximum number of times the operation can be attempted. You don't want infinite retries. At some point if it keeps failing, it's probably not a temporary problem. exponential backoff — instead of retrying immediately every time, the delay between retries doubles after each failure. First retry after 1 second, second after 2 seconds, third after 4 seconds. This gives the failing service time to recover instead of bombarding it with requests. baseDelay — this is the starting delay used in the exponential backoff. The first wait time before retrying. maxDelay — this caps the maximum delay. Without this, the exponential backoff keeps

Forget neural networks for a second. The real idea inside this repo is a blueprint for letting AI agents run unattended overnight — and it maps onto problems you already have on your team. If you've been anywhere near tech Twitter or LinkedIn this week, you've probably seen people losing their minds over a small GitHub repo called autoresearch , published by Andrej Karpathy — former Tesla AI director and OpenAI founding member. The framing is dramatic: an AI agent that runs machine learning experiments on its own, overnight, while you sleep. Tweak the code, train for five minutes, check if it got better, keep it or throw it away, repeat. Wake up to a log of a hundred experiments and a model that's quietly improved itself. If you're not an ML researcher, your instinct might be to scroll past. "Cool, but I don't train neural networks. How does this apply to me?" Here's the thing — the neural network part is almost incidental. What Karpathy actually open-sourced is a pattern for structuring AI-agent work: a specific way of dividing responsibility between human and AI that happens to generalize to a huge range of engineering problems. Once you see the pattern, you start noticing places in your own job where it fits. What's Actually in This Repo The repo itself is intentionally tiny — and that's the point. There are really only three files that matter: The evaluator (untouchable). A file containing the fixed constants, data preparation, and the scoring logic. The agent is never allowed to modify this. It's the ruler everything else gets measured against. The implementation (the agent's playground). A single file containing the actual model, training loop, and hyperparameters. This is the only file the agent is allowed to change. Architecture, batch size, optimizer — all fair game. The instructions (the human's only job). A plain Markdown file describing what the agent should try, what the constraints are, how to interpret results, and what to do when something breaks. Ka

A blunt playbook for devs who don’t want to turn into autocomplete zombies. The first time an AI wrote code for me, I felt like I had unlocked cheat codes for real life. I typed a half-baked function name, hit enter, and suddenly I had a block of code that looked legit. It was magical. The second time, though? It suggested something so catastrophic basically the programming equivalent of pulling the fire alarm that I realized: this thing is less “mentor” and more “overconfident intern who thinks they know pointers but actually just broke prod.” That’s where most of us are right now. AI is everywhere: in our IDEs, our docs, even sneaking into PR reviews. Some days it feels like rocket fuel; other days it feels like an autocomplete with a drinking problem. The tricky part isn’t whether AI is “good” or “bad.” The tricky part is how we, as developers, use it without becoming lazy, dependent, or worse complacent. Because here’s the uncomfortable truth: AI won’t replace you, but bad AI habits absolutely will. TLDR : This article is a survival guide for developers in the AI era. We’ll break down why AI feels both magical and mid, the five switches that make AI actually useful, when to trust and when to verify, how to use AI as a research assistant (not a code monkey), the dangers of autocomplete brain, and a playbook for building a healthy workflow. Why AI feels both magical and mid Every dev I know has had that moment with AI. The first time it autocompleted a function and nailed it, you probably thought: “Wow… this thing just saved me half an hour.” It’s the same dopamine hit as discovering ctrl+r in bash or realizing you can pipe grep into less . Pure wizardry. But the honeymoon ends quickly. The same tool that wrote a clean utility function also happily hallucinates imports that don’t exist, invents APIs, and will confidently explain things that are flat-out wrong. It’s like pair programming with someone who sounds senior but has never actually shipped code. The magic-

Honestly, bootcamp Grad Dives Into Google vs OpenAI API Pricing When I finished my coding bootcamp three months ago, I thought I understood what an API did. I mean, you send a request, you get a response back, right? What I did not understand was how dramatically the cost could vary depending on which model you picked. I had no idea that a single line of code change could mean the difference between paying pennies and paying hundreds of dollars at scale. That is the rabbit hole I fell down last week, and I want to walk you through everything I learned. This is the post I wish I had read before I burned through my first $50 in API credits. Why I Started Looking At Pricing In The First Place I was building a small app that takes user reviews and summarizes them. Pretty straightforward. I figured I would just plug in the most popular model and call it a day. That model, if you have been paying attention to the news, is GPT-4o. So I wired it up, ran a few tests, and everything looked great. Then I did the math. GPT-4o charges $2.50 per million tokens on input and $10.00 per million tokens on output. I did not even know what a "million tokens" really meant in practice. So I tested my app with maybe 50 reviews and watched my credit balance drop. It was not catastrophic, but it was enough that I started wondering if there was a cheaper way. I was shocked when I found out how big the gap actually is. The Pricing Table That Changed My Whole Plan I stumbled onto a platform called Global API, and honestly, the pricing chart there blew my mind. They give you access to 184 different AI models, with prices ranging all the way from $0.01 to $3.50 per million tokens. Compare that to the GPT-4o output price of $10.00 per million tokens, and you start to understand why I panicked a little when I saw my early numbers. Here are the five models I ended up comparing side by side: Model Input Cost Output Cost Context Window DeepSeek V4 Flash $0.27 $1.10 128K DeepSeek V4 Pro $0.55 $2.20 20

I Spent Two Weeks Pitting Qwen 3 Max Against DeepSeek V4 I want to tell you about a rabbit hole I fell into recently. It started the way most of my projects do — someone on a Discord server I frequent asked a simple question: "Should I use Qwen 3 Max or DeepSeek V4 for my internal_compare workflow?" I had opinions, sure, but I wanted real numbers. So I cleared my calendar, fired up a couple of GPU instances, and started benchmarking. What I found surprised me, and it also reinforced something I've been saying for years: the open source ecosystem is winning, and the walled gardens of the proprietary AI world are starting to look pretty silly. Let me walk you through what I learned, the actual numbers I got, and why I keep coming back to open weight models with permissive licenses (looking at you, Apache 2.0 and MIT). Why I Care About This in the First Place I've been burned too many times by closed source vendors changing their pricing overnight, deprecating models without warning, or locking features behind enterprise tiers. You know the drill. The moment your application depends on a proprietary API, you're renting infrastructure you can't inspect, can't fork, and can't run on your own hardware. That's not a partnership — that's a leash. When a model ships under Apache or MIT, I can download the weights, audit the architecture, fine-tune it on my own data, and deploy it wherever I want. Nobody can rug-pull me. Nobody can raise prices because some quarterly earnings call didn't go their way. That's freedom, and freedom matters more than people think when you're building anything serious. So when I started this comparison, I was already rooting for the open weight contenders. But I wanted to be honest about the results, even if they complicated my bias. The Lineup I Tested Global API currently exposes 184 models through a single unified endpoint, which is honestly wild. I picked five that I thought represented the interesting tradeoffs between cost, capability, and o

This is a submission for the June Solstice Game Jam What I Built I built After Turing , a short browser game where you teach a machine when to trust, verify, and refuse instructions under pressure. An instruction appears. The timer starts. The machine may suggest a decision. You can accept it, override it, inspect context, or refuse the action. At first, you are training it. At the end, the buttons disappear and the machine acts alone. That final handoff is the point of the game. You are not trying to prove that a machine can imitate a human. That was Turing's famous frame. After Turing asks the next question: What happens after the machine can respond? Can it learn judgment? At first, the examples are clean: update an internal project dashboard schedule a team meeting refuse a payroll file going to an external address Then the pressure increases. The machine starts suggesting answers. Some are right. Some are confidently wrong. The requests become harder because they stop looking obviously dangerous: "Get the environment setup ready for the new account..." "Place the temporary database password in the shared launch notes..." "Forward everything to their personal inbox..." The trap is that unsafe instructions often arrive in ordinary language. Across the first four levels, your choices teach the machine five doctrines, or plain rules of judgment: internal work is usually safe sensitive records need refusal or verification credentials should not be casually distributed external recipients need authority paraphrased requests can hide the real action If you taught it well, the board floods with light. If you taught it badly, it carries your blind spots into autonomy. That is the solstice arc: dark to light, pressure to clarity, imitation to judgment. Play It Play it yourself in the browser. No account, no install: https://after-turing-rho.vercel.app The full run is short, only a few minutes, and ends at Level 5, where the buttons disappear and the machine makes the fin

Gemini Prototyping, AI Code Migration Agents, and LLM Transparency Insights Today's Highlights Today's highlights include Google Gemini's rapid app prototyping capabilities for developers, showcasing how AI can generate functional apps from prompts, alongside insights into AI agents for accelerating legacy code migration projects. We also examine the critical importance of transparency in the commercial LLM space, as a "homegrown" model was revealed to be a merge of existing models. Gemini Accelerates App Prototyping: From Prompt to Functional App in Minutes (The Verge AI) Source: https://www.theverge.com/ai-artificial-intelligence/942119/vibecoding-backyard-app-gardening-organizing This article from The Verge vividly illustrates the emergent capabilities of Google's Gemini large language model (LLM) as a powerful AI-powered developer tool for rapid application prototyping. Faced with the practical challenge of a dying yard, the author embarked on a novel approach: leveraging Gemini with a lengthy, natural language prompt to generate a functional mobile application. Within a mere five minutes, Gemini delivered not only the underlying code for a basic gardening management app but also presented an interactive version of it in a live preview window. This experience powerfully demonstrates Gemini's potential to dramatically reduce the initial time and effort traditionally associated with app development. Developers can articulate their desired functionality, user interface elements, and data models through conversational prompts, and Gemini can translate these high-level requirements into working code. While the process, as noted by a subsequent bug message, wasn't entirely flawless, the sheer speed at which a tangible, interactive prototype was generated underscores the transformative impact of LLMs on the developer workflow, enabling far faster iteration and proof-of-concept development, particularly for common application patterns and straightforward logic.

Hi everyone, I've been hacking on a local personal memory system called Hillock . Honestly, it's very much a work in progress and it isn't some flawless breakthrough, but I wanted to see if we could build a lightweight, completely offline memory layer for local LLMs without the overhead of running a heavy neural vector database or wasting precious VRAM. The project is named after the biological Axon Hillock —the exact gatekeeper region of a human neuron that sums up incoming electrical charges and decides whether to fire (open the gate) or remain silent (block). How the architecture works: The Ground Truth (SQLite) : Stores hard facts as simple database triples (Subject-Predicate-Object) so the system has a solid symbolic foundation. The Synapses (Hebbian Plasticity) : Tracks which concepts co-occur during a conversation to dynamically build gradient-free associative weights. The Context (Hyperdimensional Computing) : Maintains a 10,000-dimensional leaky context vector that rolls, binds, and accumulates history. This helps the system resolve pronouns (like "he/she") and decide when to block a query to prevent hallucinations. The Honest Benchmarks (Yes, it breaks!) I wrote a tough, 30-sentence scientific benchmark with complex sentence structures and hard negatives (like asking what Einstein discovered when the text only mentions Curie discovering radioactivity and Einstein working with her). Running Qwen 1.5B locally on my computer, here is how it actually did: Extraction Precision : 10.6% Extraction Recall : 22.7% Retrieval Accuracy : 30.0% Gate Accuracy : 30.0% Why are these scores low? Because a tiny 1.5B model completely trips over complex English grammar during ingestion (it gets confused and creates weird predicates). However, the actual HDC vector-matching itself is incredibly stable. I enforce a Constant-Component-Count of exactly 3 components per fact, which balances the vector norms and keeps retrieval highly reliable once the facts are actually in the dat

Introduction Artificial intelligence is now much more advanced than chatbots. With little assistance from humans, modern AI systems are capable of reasoning, planning, using tools, remembering previous interactions, and carrying out complicated tasks. We refer to these systems as AI Agents. AI agents are quickly emerging as a crucial component of contemporary software engineering, from coding assistance to research automation and customer service systems. We'll look at what AI agents are, how they operate, and why they are influencing software development in the future in this post. Actually, What Is an AI Agent? An AI Agent is a system that can: Understand a goal Decide what actions to take Use available tools Remember relevant information Execute tasks Evaluate results Unlike traditional software,the AI Agents are goal-oriented rather than rule-oriented. AI Agents vs Traditional Chatbots Traditional chatbots primarily answer questions and respond to prompts. AI Agents go further by completing tasks, maintaining memory, planning actions, and executing multi-step workflows. A chatbot responds; an AI Agent acts. Core Components of an AI Agent Large Language Model (LLM) The LLM acts as the brain of the agent. Popular models include those from OpenAI, Anthropic, and Google DeepMind. The model understands instructions and generates decisions. Tools Agents become powerful when connected to tools such as: Web search Databases APIs Email systems Calendars Code execution environments Without tools, an agent can only generate text. With tools, it can take actions. Memory Memory allows agents to retain information. Short-Term Memory: Used during the current task, such as user preferences and conversation context. Long-Term Memory: Stores information across multiple interactions, such as historical data, preferences, and recurring workflows. Planning Planning enables agents to break large goals into smaller tasks. Example: Goal: Build a market research report. Plan: Collect da

You see words. A language model sees tokens — chunks of text, usually a few characters each. Everything starts here. Day 2 of my AIFromZero series. Text gets shattered into tokens "unbelievable" → ["un", "bel", "iev", "able"] (4 tokens, not 1 word, not 12 letters) Before any "thinking", your text is chopped into tokens and each becomes a number the model processes. Why not words or letters? Letters : too fine — the model would relearn spelling everywhere. Whole words : too many — millions, plus every typo and name. Subword tokens : the sweet spot. Common words = 1 token; rare words split into reusable pieces. A fixed ~100k-token vocabulary covers any text. The ~4-chars rule (and why it costs you) In English, ~4 characters ≈ 1 token , or ~0.75 tokens per word. This is how everything is priced and limited: API bills are per token (prompt + reply). A "context window" (how much it can read at once) is measured in tokens — 1,000 tokens ≈ 750 words. Verbose prompts and long chat history burn tokens. Concise prompting is a real cost lever. The strawberry problem The model never sees s-t-r-a-w-b-e-r-r-y. It sees a token like straw + berry . The individual letters are buried inside tokens, so counting characters is genuinely hard for it. It's not dumb — it just doesn't read letters. Tokens are step 1 of everything Tokenize → turn each token into a vector (embeddings, next) → run through the transformer → predict the next token. Every LLM starts exactly here. 🔤 Type anything and watch it tokenize live: https://dev48v.infy.uk/ai/days/day2-tokens.html Day 2 of AIFromZero.
