# Use LLM-Based Parsing and Preprocessing on DMOs with File Attachments

Process Data 360 data model objects (DMOs) that include a file attachment by selecting LLM-based parsing and preprocessing options. You can also view the process history metrics for these search indexes. Previously, LLM-based parsing and preprocessing options and process history metrics weren’t available for search indexes built with file attachment unstructured data model objects (UDMOs).

**Where:** This change applies to Data 360 in Enterprise, Performance, Unlimited, and Developer editions.

**When:** This feature is available starting July 2026.

**Why:** LLM parsing and preprocessing options process files more effectively and retrieve all available content that AI agents need. These options also provide you with fine-grained control over the data extraction process. Process history metrics provide detailed insights into the search index pipeline.

**How:** Set up file attachment ingestion in Data 360 by deploying content data streams. Then create a search index on any DMO and select **Include File Attachments** to process related file attachments.
