# Knowledge Chunk Resource

When you create a Knowledge source, Twilio AI Assistants processes that Knowledge and breaks it into discrete pieces called **Chunks**. These pieces can help you troubleshoot unexpected behavior with your Assistant.

This API returns a list of all **Knowledge Chunks** created from uploading Knowledge sources.

## Chunk Properties

<OperationTable type="properties" data={{"type":"object","refName":"assistants.v1.service.knowledge_chunk","modelName":"assistants_v1_service_knowledge_chunk","properties":{"account_sid":{"type":"string","minLength":34,"maxLength":34,"pattern":"^AC[0-9a-fA-F]{32}$","description":"The SID of the [Account](/docs/iam/api/account) that created the Knowledge resource."},"content":{"description":"The chunk content.","type":"string"},"metadata":{"description":"The metadata of the chunk.","type":"object"},"date_created":{"description":"The date and time in GMT when the Chunk was created specified in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format.","format":"date-time","type":"string"},"date_updated":{"description":"The date and time in GMT when the Chunk was updated specified in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format.","format":"date-time","type":"string"}}}} />
