# Named Entity Recognition (NER) task

> The Named Entity Recognition (NER) task identifies entities and their types — such as people, organizations, and locations — and the relationships between them.

*Type*: `prompter`

*Subtype*: see [Settings](#settings)

## Settings

<ParamField body="subtype" type="string" required>
  Enrichment algorithm and provider. Set at the `WorkflowNode` level, outside of `settings`. Allowed values:

  * `anthropic_ner`
  * `openai_ner`

  <Note>
    The preceding list applies only to Unstructured **Let's Go** and **Pay-As-You-Go** accounts.

    For Unstructured **Business** accounts, to get your current list of available values, contact your
    Unstructured account administrator or Unstructured sales representative, or email Unstructured Support at
    [support@unstructured.io](mailto:support@unstructured.io).
  </Note>
</ParamField>

<ParamField body="provider_type" type="string" required>
  Provider that matches the prefix of `subtype`. Allowed values: `anthropic`, `openai`.
</ParamField>

<ParamField body="model" type="string" required>
  Model to use for NER. For a full list of the models available in Unstructured, see [Available models](/api-reference/workflow/models).
</ParamField>

<ParamField body="prompt_interface_overrides.prompt.user" type="string">
  Alternative prompt to pass to the NER model. Default: none (uses Unstructured's internal default prompt).

  If specified, you must provide the complete prompt in the following format. For best results, limit changes to the entity types, relationship types, or clarifying instructions only — changing other parts of the prompt may produce unexpected results.

  ```text theme={null}
