**TLDR:** An organized collection of data that enables a model to be trained, evaluated, or tested.

<p>A dataset is the fundamental raw material that feeds AI systems. What a model can learn, which patterns it can see, and how reliable its outputs will be depend heavily on the quality of the dataset. For that reason, a dataset is not just a file full of examples; it is a strategic design element that shapes model behavior. A strong dataset represents the problem domain well, offers sufficient diversity, minimizes labeling errors, and reflects real operating conditions as closely as possible. Building a strong model on weak data is difficult; with strong data, even moderate models can often create significant value.</p>
