People often use \u201cmodel,\u201d \u201ctool,\u201d and \u201capp\u201d as if they mean the same thing. They describe different layers. Knowing the difference helps you understand what a product can do and what you are comparing.<\/p>\n
A model is a trained component that processes input, such as text or images, and produces an output. A company may offer access to a model through an API or include it in a product. The model alone does not define the user interface, account settings, or access to files and the web.<\/p>\n
A tool is a capability the system can use, such as search, calculation, or a connection to an external service. A model may request a tool, but the application and its permissions control what actually runs. A model explaining how to search is not proof that it has live web access.<\/p>\n
An app is the product you use: its interface, account, settings, services, and available tools. It may use one model or several. The available model may also change by plan or over time, so the app name and model name are not necessarily interchangeable.<\/p>\n
ChatGPT is an assistant and product offered by OpenAI. Models provide underlying capabilities. Search and file analysis, where available, are features or tools in the product experience. Availability can depend on plan, region, and settings; check the product\u2019s current documentation.<\/p>\n
When comparing options, ask which layer you mean: a model\u2019s capability, a tool\u2019s function, or an app\u2019s full experience. Privacy, price, and usage limits often depend on the product and plan, not just the model name.<\/p>\n
The model processes information; a tool extends what the system can do; the app assembles those pieces into something people use. This is an explanatory distinction, and vendors may use the terms differently in marketing.<\/p>\n
