It includes enough data ingestion, scoring, and data retention to explore and build small projects. Pro: Best suited for small teams of up to 5 people who are regularly running experiments or evaluations that require increased usage limits and longer data retention. Additional usage beyond included limits is billed flexibly, making it great for teams with growing or varying workloads. Enterprise: Recommended for larger organizations or teams with custom needs such as high volumes of data, special security requirements, on-premises deployment, or dedicated support."},"name":"Which plan is right for me?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Processed data refers to data ingested when you send data to Braintrust, not retained storage. After you exceed your monthly quota, deleting data does not lower processed data. The cumulative amount ingested counts toward your monthly total, calculated from the first day to the last day of each calendar month."},"name":"What does processed data mean?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Scores are used to measure the results of offline or online evaluations run in Braintrust.

Your monthly total is calculated cumulatively from the first to the last day of each calendar month."},"name":"What are scores?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"You can track your usage by selecting View usage details in Settings > Billing.

You can enable on-demand usage or upgrade to the Pro plan at any time via the the Billing page in Settings. When you sign up for the Pro plan, you'll immediately be charged a prorated amount of the monthly $249 platform fee. For example, if you sign up on the 15th of the month, you'll pay about half of the monthly fee. On the 1st of the following month, you'll be charged the full $249 fee plus any additional usage-based charges incurred during the previous month. Charges will be processed automatically using the credit card provided."},"name":"How does billing work?"},{"@type":"Question","acceptedAnswer":{"@type":"Answer","text":"Yes, we offer 6–12 months of free access to the Pro plan for qualifying startups. To qualify, you must be a new Braintrust customer and have raised at least $100K in funding. You can apply for the program by visiting the startups page."},"name":"Do you offer discounts for startups?"}]}
