The Bill for an AI Agent Isn't the Token Price
A wrong turn in an AI agent's run doesn't just produce a wrong answer. It adds model interactions, tool calls, latency, and human intervention before the agent gets anywhere useful. That is the mechanism behind the budgeting point AWS makes in its Bedrock material: token prices set the cost of each interaction, while reasoning quality helps determine how many interactions the work requires — and the total cost of finishing the task depends on both. So the sticker price per million tokens is only half the arithmetic. A model that plans well and recovers cleanly can be the cheaper one to run even at a higher per-token rate, while a cheaper model that wanders bills you for the wandering.

The number worth watching is interactions per task, not dollars per token — one shows up on the pricing page, the other only shows up in the invoice.
Cutting the per-token price still lowers the cost of every single interaction, which is not nothing. It just doesn't rescue a model that keeps taking wrong turns.
