New to AI? You only need three labels to begin: the company makes the technology, the model is the engine, and the app is what you open. A method is a recipe developers use to build or teach AI.

Made byGoogle researchers
What kind of thing?Picture engine family
Can I use it directly?Usually a building block inside an app. It is not a chat website.

Look at the dog, flower and bicycle. Recognising what is there and finding where it is are two different AI jobs.

See the idea in three steps

A simple illustration of the idea. Results depend on the model, training and app.

A familiar way to picture it

An everyday analogyThink of an engine designer trying to get useful performance while keeping resource use manageable.

An analogy helps you understand the main idea. It is not a description of every technical detail.

A simple EfficientNet example

A suitably trained app helps sort photos of leaves into different plant types.

1

A developer chooses categories for a picture task.

2

An EfficientNet-based system learns relevant image patterns.

3

The system suggests a category for a new picture.

Is EfficientNet an app like ChatGPT?

No. EfficientNet is a family of image recognition network designs. Developers can use it inside apps. ChatGPT is an assistant interface; these names refer to different kinds of things.

Where can I try it or learn more?

Usually a building block inside an app. It is not a chat website.

Google research ↗

A maker’s page or research page may explain the technology rather than provide a chat box. Available models, features and access can change.

A small activity for you

Sort pictures of leaves into a few categories. Then imagine doing it for thousands of pictures. That is why a developer might use an image recognition model.

You do not need to memorise model sizes or write a program to understand this lesson. First explain the idea in your own words. If you want to build an app later, the official resources are your next step.
