Artificial intelligence has become much easier to use thanks to modern AI systems that can understand and generate human-like language. Today, people use AI tools for writing, programming, research, brainstorming, summarization, customer support, data analysis, and many other tasks. However, the quality of an AI-generated response often depends heavily on the instructions you provide. This […]
Customer support is one of the most important parts of any business. Customers expect quick answers, helpful solutions, and support whenever they need it. But as a business grows, handling every customer question manually becomes difficult. Support teams may spend hours answering the same questions, checking order details, updating tickets, and routing requests to the […]
Large Language Models, or LLMs, can process large amounts of text, but they cannot handle unlimited information at once. Every LLM has a limit on how much information it can consider during a single interaction. This limit is called the context window. The context window is one of the most important concepts to understand when […]
Tokens are one of the most important concepts to understand when learning about modern artificial intelligence, especially Large Language Models, or LLMs. AI models do not usually read text exactly the way humans do. When you write a sentence such as: an AI model first breaks that text into smaller pieces. These pieces are called […]
Large Language Models, or LLMs, are the technology behind many modern AI systems that can understand and generate human-like language. They can: But how do they actually work? At a high level, an LLM learns patterns from enormous amounts of text and then uses those learned patterns to predict what token should come next. That […]
Large Language Models, commonly called LLMs, are one of the most important technologies behind modern generative AI. They can understand and generate human-like text, answer questions, summarize documents, write code, translate languages, classify text, assist with research, and perform many other language-related tasks. Examples of what an LLM can do include: Most modern LLMs are […]
Generative AI is one of the most important and fast-growing areas of artificial intelligence. Unlike traditional AI systems that mainly analyze or classify existing data, generative AI can create new content. It can generate: For example, a generative AI system can write an article, create an image from a text prompt, generate programming code, summarize […]
Testing becomes increasingly important as a Node.js application grows. At the beginning, you may manually check whether a function works. But as your application gets larger, manually testing every feature becomes slow and unreliable. A better approach is to automate your tests. A popular and flexible testing stack for Node.js uses three libraries: Together, they […]
Most Node.js applications depend on a database. Whether you are building an e-commerce application, a blog, an authentication system, or a REST API, your application usually needs to store and retrieve data. For example: Testing only the JavaScript logic is not always enough. You also need to make sure that your application correctly communicates with […]
