LLM prompts are the interface between an application or user and a large language model. A prompt can contain instructions, context, examples, constraints, data, and an expected output format that together shape how the model interprets a task and generates a response.

Artificial intelligence is no longer a separate specialty that application developers can ignore. Modern software increasingly includes language models, recommendation systems, semantic search, computer vision, AI agents, embeddings, and model-powered automation.

Agentic engineering is the discipline of building AI systems that can reason about goals, choose actions, use tools, observe results, maintain state, and continue working until a task reaches a useful outcome. The difficult part is not making a model generate text; it is designing the control system

Artificial intelligence covers much more than large language models. Modern AI systems combine machine learning, neural networks, language and vision models, probabilistic methods, embeddings, agents, evaluation, and specialized infrastructure.

Building an AI prototype is relatively easy. Building an AI application that behaves predictably under real production traffic is much harder. Production systems must handle model failures, hallucinations, changing data, long contexts, tool execution, security boundaries, traffic spikes, latency req

AI monitoring and evaluation is the process of measuring whether an AI application is producing useful, correct, reliable, safe, and cost-effective results before and after deployment. Traditional monitoring can tell whether an API is available or slow. AI systems need additional measurements becaus

Scaling AI applications means designing AI-powered systems so they can handle increasing traffic, larger workloads, longer contexts, more users, and higher model usage without unacceptable increases in latency, failures, or cost. The challenge is different from scaling a conventional API because an

AI security is the practice of protecting AI applications, their data, models, tools, infrastructure, and users from attacks and unintended behavior. Traditional application-security controls still apply, but AI systems introduce additional attack surfaces because they process natural-language instr

AI application architecture describes how language models and other AI components fit into a production software system. The model is usually only one component. A real AI application also needs APIs, application logic, data stores, retrieval systems, tools, security controls, caching, queues, obser

AI model training is the process of adjusting a model's parameters using data so that it learns useful patterns and behaviors. Fine-tuning continues that process from an already trained model, adapting it to a more specific task, domain, style, or behavior.

AI hallucinations are outputs in which an AI model generates information that is incorrect, unsupported, fabricated, or inconsistent with the available evidence while presenting it as if it were valid. A language model may invent a fact, cite a source that does not exist, produce an incorrect API me

AI tool calling is a technique that allows an AI model to request operations from external software systems through predefined interfaces. Instead of being limited to generating text from information already available in its context, a model can request data from APIs, search databases, perform calc

AI agents are AI systems that use a model to decide what actions to take while working toward a goal. Instead of generating one response from one prompt, an agent can repeatedly inspect its current state, choose an action, use tools, observe the result, and decide what to do next.

Retrieval-Augmented Generation (RAG) is an AI architecture that retrieves relevant information from an external knowledge source and provides that information to a language model as context before generating an answer. Instead of relying only on knowledge encoded in model parameters, the application

Retrieval-Augmented Generation (RAG) and fine-tuning solve different problems in AI applications. RAG supplies external information to a model at inference time, while fine-tuning changes the model itself by training it on additional examples.

Vector databases are databases and search systems designed to store high-dimensional vectors and efficiently find vectors that are similar to a query vector. They are commonly used with AI embeddings to power semantic search, retrieval-augmented generation, recommendation systems, duplicate detectio

AI embeddings are numerical vector representations of data that capture useful semantic relationships. Text, images, products, users, documents, source code, and other objects can be converted into embeddings so that software can compare them mathematically rather than relying only on exact keywords

AI prompt engineering is the practice of designing the instructions and context given to an AI model so that it produces useful, predictable, and appropriately constrained results. In production systems, a prompt is not merely a question written in natural language. It acts as part of the applicatio

AI tokens are the units that large language models process instead of raw words or characters. Prompts, generated responses, conversation history, retrieved documents, and tool results are converted into tokens before they enter a model.

Transformers are neural-network architectures designed to process relationships between elements in a sequence using a mechanism called attention . They are the foundation of most modern large language models and are also widely used for images, audio, video, and multimodal AI.

Large Language Models (LLMs) are deep neural networks trained on large collections of text, code, and other data to understand and generate language. They power chat assistants, code-generation tools, document processing, semantic search, retrieval-augmented generation, AI agents, and many other mod

Neural networks are machine-learning models built from layers of interconnected mathematical units that learn how to transform input data into useful outputs. They power many modern AI systems, including image recognition, speech processing, recommendation systems, and large language models.

Machine learning (ML) is a branch of artificial intelligence in which software learns patterns from data instead of relying entirely on rules written by developers. A trained model can use those patterns to classify inputs, predict values, rank alternatives, detect anomalies, or support automated de

Artificial intelligence (AI) is the broad field of building computer systems that perform tasks normally associated with human intelligence, such as understanding language, recognizing patterns, making predictions, generating content, and selecting actions.
