New terms are useful only when you understand which problem a technology solves, what it requires and where its limits lie. This library connects core concepts to real organisational situations and leads from a simple explanation to the next useful question.
You do not need to understand every technical detail.
A sound decision starts with a clear view of purpose, data flow, responsibility and limitations. These articles help you develop that view.
Six ways into the subject
AI explained simply
This is not a course in mathematics or model training. You will learn what central terms mean in day-to-day business, which role they play in a solution and why a model alone is not a finished application.
What you will learn
what an LLM processes and how it produces an answer
why an AI model is not the same as a finished application
Business knowledge is usually spread across documents, wikis, databases and operational systems. The key questions are not merely whether AI can access it, but which source it may use in a given situation and how an answer is supported.
What you will learn
how retrieval-augmented generation, or RAG, works at a high level
how standard, hybrid, multi-hop and GraphRAG differ
Automation ranges from a simple rule to a system that chooses steps and uses tools. The right degree of flexibility depends on the task, risk, exceptions and required control.
The guides surface assumptions and help domain teams, IT and leadership examine the same decision from different perspectives. They do not replace analysis, but create a shared, defensible starting point.
Privacy in AI is not a single product setting. The purpose, full data flow, participating providers and controls inside the organisation determine what is appropriate. These articles turn provider terminology into questions that support a defensible decision.
What you will learn
which data an AI application actually processes and where additional storage can arise
why training, retention, data location and Zero Data Retention are separate commitments
Errors cannot be prevented by a better prompt alone. Responsible use combines suitable tasks, representative tests, limited permissions, transparent sources and explicit ownership.
What you will learn
why plausible but false answers occur
where systematic bias arises and how it can be tested
AI model, application and platform: what is the difference?
An AI model processes inputs and generates outputs. An AI application combines one or more models with a specific task, interface and business logic. An AI platform provides shared technical and organisational building blocks for multiple applications.
RAG, fine-tuning or a direct API: Which should you use?
RAG is suitable for current, source-based knowledge from documents. Fine-tuning is suitable for recurring tasks or consistent desired behaviour learned from strong examples. A direct API is appropriate when the application needs exact live values, structured records or transactions from a business system. Many enterprise solutions combine these approaches.
Tool use is the mechanism by which an AI model selects an available tool and produces structured input for it. The actual query or action is performed by the application or a controlled tool runtime.
An AI use case is worth pursuing when it measurably improves a frequent or important problem, suitable data and clear ownership are available, and potential errors can be detected and controlled with reasonable effort.
An application receives business data, may add further context and sends the resulting content to an AI model for processing. Whether inputs and outputs are then logged, retained, used for other purposes or passed to additional services depends on the product, configuration and contractual terms.
Evals are structured assessments in which an AI solution is run against representative test cases and scored using predefined criteria. They reveal how reliably it performs a specific task and where its limits lie.
