The clean-path steps this benchmark prices:
This path runs 10 steps: 5 tool calls and 5 decision points. Tool steps make two model calls each, and the agent re-reads its growing context on every call. That compounding is why one Dependency Patching outcome costs about 37x a single chat message ($0.870 on Claude Sonnet 4.6), not the price of one message.
These figures are modeled estimates, not metered bills. We price a generic, representative Dependency Patching workflow across 24 models using the same cost engine as the live estimator, at each model’s published list price (checked 25 Oct 2026), under documented default assumptions for planning loops, tool calls, memory retrieval, sub-agents and context size. Your own process will differ, so use these as starting points, tune the assumptions in the estimator, and validate against your real usage. Illustrative estimates, not financial advice.
On the clean path with default assumptions, an agent for Dependency Patching costs about $0.0290 to $2.90 per outcome depending on the model, or roughly $290 to $29,000 per month at 10,000 outcomes. The cheapest model here is Claude Haiku 5.5 at $0.0290; the most expensive is GPT-6 Astra at $2.90.
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 Dependency Patching that adds up to about 37x the cost of a single chat message.
Across the 24 models benchmarked, Claude Haiku 5.5 is cheapest at $0.0290 per outcome and GPT-6 Astra is the most expensive at $2.90. 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.
These are modeled estimates, not metered bills. Each figure prices a generic, representative Dependency Patching workflow across 24 models with the same cost engine as the live estimator, at each model's published list price (checked 25 Oct 2026), under documented default assumptions for planning loops, tool calls, memory retrieval, sub-agents and context size. Your own process will differ, so treat these as starting points, tune them in the estimator, and validate against your own usage.
