# topics

> Define topics within model files.

<Note>
  On December 10, 2024, we deprecated this field in favor of giving topics their own file. Model files that contain this field will continue to function as they always have, but going forward you'll encounter an error if you attempt to add `topics:` to a model file.

Refer to the [Topics documentation](/modeling/topics) for more information.
