The clean-path steps this benchmark prices:
This path runs 8 steps: 3 tool calls, 1 reasoning step, 4 decision points and 0 human checkpoints. Tool steps make two model calls each, and the agent re-reads its growing context on every call. That compounding is why one Claims Adjudication outcome costs about 22x a single chat message ($0.518 on Claude Sonnet 4.6), not the price of one message.
On the clean path with default assumptions, an agent for Claims Adjudication costs about $0.0249 to $1.73 per outcome depending on the model, or roughly $249 to $17,280 per month at 10,000 outcomes. The cheapest model here is GPT-4o mini at $0.0249; the most expensive is Claude Fable 5 at $1.73.
An agent does not make one model call. It plans, calls tools, retrieves context and re-reads its growing working context on every step. For Claims Adjudication that adds up to about 22x the cost of a single chat message.
Across the 13 models benchmarked, GPT-4o mini is cheapest at $0.0249 per outcome and Claude Fable 5 is the most expensive at $1.73. A cheaper model is not always the right choice, but it sets the floor for this workflow.
The biggest levers are prompt caching on the base context, fewer planning loops, smaller tool results, less retrieval, and choosing a cheaper model where quality allows. You can test each lever in the live estimator.
