# Tags

> Tags are a fantastic way to organize your Sessions based on data known by the developer but not by AgentOps. Ex: `paid-user`, `v3`, `recruiter-agent`

# How to use Tags

Tags belong to [Sessions](/v1/concepts/sessions) and are a fantastic way to organize your Sessions.

## On `init()`

Passing `tags` into the `init` function will assign these tags to the all subsequent Sessions.

<CodeGroup>
  ```python python theme={null}
  agentops.init(tags=['test tag'])
  ```
</CodeGroup>

`tags` can also be passed into the `start_session` function for better organization.

<CodeGroup>
  ```python python theme={null}
  agentops.start_session(tags=['test tag'])
  ```
</CodeGroup>
