Guardrail Cost Dashboards

Guardrail costing

Guardrail Costing provides a structured framework to track and manage expenses generated by Amazon Bedrock Guardrails when they are used for content moderation and filtering. It surfaces real-time cost visibility across configured filtering mechanisms and helps users understand how spend is distributed across guardrail policy types.

Guardrails can be invoked from:

• Prompt Playground

• Recipes

• Copilots

Cost is calculated based on the guardrail evaluations performed through these experiences within the selected time range.

Cost categories included in Guardrail Costing

• Content Filters: Cost for applying content safety filters.

• Denied Topics: Cost incurred when configured topics are restricted or denied.

• Word Filters: Cost for checking content against configured word/phrase filters.

• Sensitive Information: Cost for filtering or blocking sensitive information.

• Contextual Grounding: Cost for grounding responses within allowed context.

Costing and Billing Details

Amazon Bedrock Guardrails charges are incurred only for the policy types configured in the guardrail.

Charging depends on whether content is blocked and where enforcement happens:

• If a guardrail blocks the input prompt

  • Charged for guardrail evaluation of the input prompt

  • No charges for foundation model inference (model call does not occur)

• If a guardrail blocks the model response

  • Charged for guardrail evaluation of:

    • input prompt, and

    • model response

  • Charged for foundation model inference because a response is generated prior to guardrail evaluation

  • Charged for the model response that was generated prior to the guardrail’s evaluation

• If a guardrail does not block the input prompt or the model response

  • Charged for guardrail evaluation of:

    • input prompt, and

    • model response

  • Charged for foundation model inference

Guardrail Dashboards

The Guardrail Costing dashboard provides a consolidated view of guardrail spend and activity across the selected time range. It includes time controls and two primary metrics:

1. Total Cost

2. Total API Requests

Dashboard controls

• Date range (From/To): Defines the analysis window; all metrics update to reflect the selected period.

• Granularity

  • Hourly: Automatically displays data for the previous day and the current day

  • Daily: Displays data for the last month up to the current date

• Clear filters: Resets applied filters and restores the default view for the selected granularity.

Total Cost

• Displays the total guardrail-related cost incurred within the selected time range.

• Provides a breakdown of total spend by policy category:

  • Content Filters

  • Denied Topics

  • Word Filters

  • Sensitive Information

  • Contextual Grounding

• Reflects guardrail usage across Prompt Playground, Recipes, and Copilots.

Total API Requests

• Displays the total number of API requests processed by guardrails within the selected time range.

• Visualizes request volume over time to show usage patterns based on hourly or daily granularity.
