Full Line code completion
The Full Line code completion feature uses a locally run deep learning model to suggest entire lines of code.
Suggestions are displayed in the editor in gray italics as you type Java, Kotlin, JavaScript/TypeScript, or CSS code. To accept the suggestion, press Tab.
The IDE formats all suggestions and adds required brackets and quotes.
Each supported language has its own set of suggested code checks. The most basic ones, like unresolved reference checks, are available for most of the languages to guarantee that the IDE doesn't suggest non-existent variables and methods.
Full Line completion supports auto-import and uses smart filtering to avoid showing suggestions that tend to be canceled explicitly or deleted right after they were accepted.
In IntelliJ IDEA, Full Line completion is available also for Python, TypeScript, PHP, Go, and Ruby. To be able to use the feature with these languages, install a corresponding language plugin as described in Install plugin from Marketplace.
Before you start working with Full Line code completion, note that:
Full Line code completion is currently not supported in Remote Development.
Full Line code completion requires a computer with a 64-bit processor or an x86 processor that supports AVX2.

Press Ctrl+Alt+S to open the IDE settings and select Editor | General | Code Completion.
In the Machine Learning-Assisted Completion section, select Enable Full Line suggestions and select the languages that you want to use Full Line completion with.
Models for Java and Kotlin are bundled with IntelliJ IDEA.
For some languages, for example, for CSS and JavaScript / TypeScript, you need to manually download models by clicking Download Model to enable completion.
Full Line completion runs locally using the models that are downloaded to your computer. You can choose the way with which these models are updated from the Download models drop-down list. You can update the models automatically, manually, or confirm every update in a notification.
