Message Credits
Message credits are a way to measure and track the usage of AI-generated responses in Thinkstack. Each time the AI responds to a user, it consumes a specific number of message credits based on the AI model used.
How Are Message Credits Calculated?#
Every AI response equals one message credit, but the total credits consumed depend on the model you’ve selected for your chatbot.
