This section is for billed sessions in the legacy Power Virtual Agents license, which was available for purchase starting on December 1, 2023. This legacy license is no longer available for purchase starting on January 1, 2024.
A billed session is an interaction between a customer and an agent. It represents one unit of consumption. The purchase of a Copilot Studio license includes a specific number of billed sessions. Copilot Studio pools this capacity across the entire tenant. Your consumed capacity isn't reported at the tenant level. However, you can view consumption for individual agents.
A billed session begins when a user topic or premium functionality is triggered. A billed session ends when one of the following conditions is met:
The user ends the chat session. When the agent doesn't receive a new message for more than 30 minutes, the session is considered closed.
The session is longer than 60 minutes. The first message that occurs after 60 minutes starts a new session.
The session has more than 100 turns. A turn is defined as one exchange between a user and the agent. The 101st turn starts a new session.
Frequently asked questions
What's the difference between total sessions, engaged sessions, and billed sessions?
Billed sessions are used to measure usage against the capacity that is allocated when you purchase a license. For more information, see the Microsoft Power Platform Licensing Guide.
Total sessions and engaged sessions are metrics of analytics sessions, used to determine how efficient an agent is in addressing a user's questions.
Billed sessions and analytics sessions are distinct and independent. For more information, see Analyze agent performance and usage.
Where can I see the total number of billed sessions for my organization?
You can only view billed sessions for individual agents.
If I'm on a trial subscription but have some billed sessions, do I have to pay?
Not necessarily. The trial offer provides you with some billed sessions.
Do the chats in the embedded test chat count as billable?
Sessions that use the embedded test chat don't count toward billed sessions.
If an environment is in overage, do the limitations apply to all environments?
No. Limitations only apply to the environments in overage. Other environments' allocated messages aren't affected.
