What are credits?

On April 29th 2025, Voiceflow will move to a credit-based billing system. This system aims to simplify billing, make costs more predictable, and give you full visibility into your usage. This course is designed to help you optimize your AI agent to reduce the number of credits it consumes, saving you money while still keeping your agent powerful.

‍

What uses credits?

Most actions that your AI agent makes will consume credits. These include:

• Each message sent by your agent
• Each minute your agent spends on a call
• LLM-generated responses
• Text-to-speech minutes

‍

What doesn't use credits?

Some actions on Voiceflow don't consume credits. These include:

• Running functions, although messages sent by functions do consume credits
• Querying the Knowledge Base

Calculate your current usage

To get started, we recommend calculating your current usage using our calculator. This will give you an estimate of how many credits we expect your agent to consume.
