Copy This Prompt - Modelling Agent Cost
Prompt
Help me build a cost model for an agent. I know the cost varies a lot per task, so I want a distribution rather than an average.
THE TASK: [what the agent does]
TOOL CALLS IN AN EASY CASE: [number]
TOOL CALLS IN A HARD CASE: [number]
ROUGHLY WHAT SHARE ARE HARD: [your estimate]
CONTEXT SIZE: [roughly how much text accumulates, tool results, documents, conversation]
MODEL: [which one]
EXPECTED VOLUME: [tasks per month]
Please:
1. Estimate cost per task for an easy case and a hard case, showing your working. Remember later steps carry more context.
2. Give me a rough distribution and both the median and the mean. Tell me how far apart they are.
3. Estimate monthly cost at my volume, and at 5x.
4. Recommend a per-task cap, steps, time and cost, and tell me what share of tasks would hit it.
5. Compare against what a human costs to do this task, and tell me the volume at which this stops making economic sense.
6. Name the single change that would most reduce cost, and what it would cost me in capability.
Flag that model pricing changes and I should check current rates.
