# Enrichment node

> Configure an Enrichment node to add AI-powered enhancements to partitioned document elements, including image descriptions, table summaries, HTML representations, named entity recognition, and generative OCR.

[Learn about the available enrichments](/concepts/enriching/overview).

<Warning>
  Unstructured can potentially generate image summary descriptions, table summary descriptions, table-to-HTML output, and generative OCR optimizations, 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, table summary description node, table-to-HTML output node, or generative OCR optimization node is added.
  * With a **Partitioner** node set to use the **VLM** partitioning strategy. No image summary description node, table summary description node, table-to-HTML output node, or generative OCR optimization node is needed (or allowed).

  Even with these configurations, Unstructured actually generates image summary descriptions, table summary descriptions, and table-to-HTML output only for files that contain images or tables 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, table summary descriptions, or table-to-HTML output 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 or tables.

  Unstructured never produces generative OCR optimizations for workflows with a **Partitioner** node set to use the **Fast** partitioning strategy.
