# Image Description task

> The Image Description task uses a vision language model to generate text-based summaries of detected images in partitioned documents.

*Type*: `prompter`

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

<Warning>
  Unstructured can potentially generate image summary descriptions only for workflows that are configured as follows:

  * With a **Partitioner** node set to use the **Auto** or **High Res** partitioning strategy, and an image summary description node is added.
  * With a **Partitioner** node set to use the **VLM** partitioning strategy. No image summary description node is needed (or allowed).

  Even with these configurations, Unstructured actually generates image summary descriptions only for files that contain images and are also eligible
  for processing with the following partitioning strategies:

  * **High Res**, when the workflow's **Partitioner** node is set to use **Auto** or **High Res**.
  * **VLM** or **High Res**, when the workflow's **Partitioner** node is set to use **VLM**.

  Unstructured never generates image summary descriptions for workflows that are configured as follows:

  * With a **Partitioner** node set to use the **Fast** partitioning strategy.
  * With a **Partitioner** node set to use the **Auto**, **High Res**, or **VLM** partitioning strategy, for all files that Unstructured encounters that do not contain images.
</Warning>

## Settings

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

  * `anthropic_image_description`
  * `bedrock_image_description`
  * `openai_image_description`
  * `vertexai_image_description`

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

  </Note>
</ParamField>

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

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