Model

Also known as: AI Model, ML Model

In one sentence

The trained AI system that contains all the patterns and knowledge learned from data. It's the end product of training—the 'brain' that takes inputs and produces predictions, decisions, or generated content.

Explain like I'm 12

After an AI studies millions of examples, the 'model' is what it becomes—like how your brain after years of school becomes something that can answer questions and solve problems.

In context

When people say 'GPT-4' or 'Claude,' they're referring to specific models. Each model has a particular size (measured in parameters), was trained on specific data, and has distinct strengths. Companies choose between models based on their needs: GPT-4 for complex reasoning, Whisper for speech-to-text, DALL-E for image generation, and Codex for code. Models can be open-source (downloadable and self-hosted, like LLaMA) or proprietary (accessed only through APIs, like GPT-4).
