Agent Bricks Cost and Billing

Prashant_151 · ‎11-17-2025

This is regarding agent bricks and want to understand DBU consumed while creating a knowledge assistant agent. Can anyone please share any video or documentation which will help me in this regard..

Let's say I take a pdf on which we want Knowledge assistant agent. So want to understand 2 things:

DBU consumed during creating agent
DBU consumed while using agent in playground

I am referring this https://docs.databricks.com/aws/en/admin/system-tables/billing.

I have tried using system.billing.usage but it shows null for agent bricks id and product_features.agent_bricks.problem_type. So, it's not clear how much dbu is getting consumed.

Hi @Prashant_151 ,

This is still a beta products so maybe that's why you don't s anything at system.billing.usage table.

But give official FAQ for beta-products situation for Agent Bricks: Knowledge Assistant looks following:

Beta Products | Databricks

So you have a couple of factors that influence your costs, namely:

Knowledge Sources: Billed for the knowledge source size via
- Jobs Serverless for document parsing and ingestion
- Mosaic AI Foundation Model Serving for embedding,
- Mosaic AI Vector Search for the index created (e.g., 1GB of PDFs results in roughly 80K vectors)
Orchestration: Billed via Mosaic AI Model Serving based on the required concurrency.
Inference: Billed via Mosaic AI Foundation Model Serving at a promotional rate of 1 DBU (or lower) per answer.
