AI Fundamentals: Dense Models vs MoE
The previous article covered NLP and NLU, the conceptual field behind language models. This last one closes the series by going back to architecture: the difference between dense models and MoE, which parameters are actually activated for each token, and why that changes the math on cost and memory, a topic that had already come up in the article on quantization and local use.
AI Fundamentals: NLP and NLU: What They Are, Differences, Uses and Practical Examples
In the previous articles the focus was on LLMs, prompts, agents and tools, that is, generative AI as it appears today. This article takes a step back to the broader field that underpins all of it: natural language processing. The idea is to tell NLP and NLU apart (plus PLN, the acronym you will see in Portuguese-language material), see where each one comes into play in practice, and understand why these concepts still hold even after LLMs.
AI Fundamentals: Prompts, Hallucination and Agents
So far we have seen what an LLM is, what it is made of and how it is trained and run. This article covers what happens at use time: how the prompt influences the answer, why the model hallucinates, and how agents and tools solve part of that problem, going beyond just generating text. At the end there is a mind map that recaps the terms from the first three articles.
AI Fundamentals: Training, Inference and Quantization
In the previous article, the idea was to understand what an LLM is, how it breaks text into tokens and what parameters and the context window mean. Here the focus shifts from “what the model is” to “how it runs”: the two main phases, training and inference, and quantization, which is what makes it feasible to fit larger models on limited hardware.
AI Fundamentals: AI, LLMs, Tokens and Parameters
Today, the most visible part of AI for developers is generative AI, especially LLMs, which process text as tokens, use a large number of parameters tuned during training, and generate outputs by predicting the most likely next unit of text given a context.
WordPress powers 34% of the world’s websites
WordPress is the most popular content management system in the world, powering about 34% of all websites. But today we are not here to talk about how versatile and practical it is to use WordPress to build websites and blogs — we also need to pay attention to security. It may be easy to use, but without a good security configuration our website can be easily hacked.
AI-Powered Digital Scams Are Becoming More Sophisticated and Harder to Detect
December 2023, Brazil — The evolution of artificial intelligence (AI) technology has brought both significant advances to society and emerging challenges in the field of digital security. Recently, Brazil witnessed an alarming example of the malicious use of AI, in which digital scams became more sophisticated and harder to detect.
Exploring the Future: Innovations in Artificial Intelligence

The Advantages of Building a Custom ChatGPT for Your Needs
Have you heard about ChatGPT customization? If you are looking for an AI solution to meet the specific needs of your company or project, this is an option worth considering. Setting up a custom ChatGPT offers a number of advantages that can make all the difference to your success. In this article, we will explore some of the main advantages of this approach.
SEO: how it can help you grow on Google
The internet is an environment that has always been constantly growing, both in the number of people gaining access to it and in the number of websites, blogs, and web pages that appear every day. To make it easier for users to find what they need in this vast sea of content, there are search engines such as Google, Bing, and Yahoo. Search engines, as the name suggests, search for everything on the internet that is accessible. Through algorithms, they are quite precise in delivering search results. However, you may have noticed that only a few results show up on the first page, even though it is very likely to match what you are looking for. According to Advanced Web Ranking, the CTR (click-through rate) of Google’s first page is around 31%, while the second page gets 15%. This makes the dispute for the first page fierce, because that is where companies, agencies, bloggers, and influencers want their content to be. But don’t worry — the path to the top of the search engines is no mystery, and it is within reach of anyone willing to create content for the internet. That is exactly what SEO techniques are for — essential for anyone who wants to start creating content for the internet and stand out. In this article you will learn a bit about them and how to use them.
