### Answer
Based on the available documentation, I can provide some clarity on AI QA pricing:
**Workspace-level pricing**: For each workspace, AI QA is free for the first 100 minutes of usage [(1) ](
) . After the free usage, AI QA is priced at $0.10 per minute of analyzed call time .
The pricing structure indicates this is charged at the workspace level (across all agents in the workspace) , not per individual agent .
**Regarding your other questions**: The available documentation doesn't explicitly specify whether QA analysis runs on all calls by default or needs to be enabled per agent, nor does it clarify whether charging is based on total call duration versus only the analyzed portion.
For these specific implementation details, I'd recommend checking:
