Microsoft Phi, explained simply.
Microsoft Phi is smaller AI engines developers can put inside their own software.
← Start with the AI basicsNew 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.
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 analogy helps you understand the main idea. It is not a description of every technical detail.
A simple Microsoft Phi example
An app using a suitable Phi model can turn a long paragraph into a short summary.
A developer chooses a Phi version for a suitable task.
The developer puts it inside software, such as a writing helper.
The person using that software sees a result without needing to handle the engine.
Is Microsoft Phi the same as Copilot?
No. Phi is a family of models. Copilot is a product name used for Microsoft assistants. A model family and an assistant product are different layers, even when one company is involved.
Where can I try it or learn more?
Mainly a building block. Phi and Microsoft Copilot are not the same product.
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
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.
