Question 1

How does the agent loop cost calculator work?

Accepted Answer

It simulates multi-turn agent interactions where context accumulates each iteration. You provide tools per loop, tokens per tool call, loop count, model pricing, and system prompt size. The calculator computes total tokens, cumulative cost, per-iteration cost, and suggests an optimal iteration limit based on cost/value ratio.

Question 2

Which models are supported?

Accepted Answer

Claude Opus, Claude Sonnet, Claude Haiku, GPT-4, and GPT-4o-mini. Each has distinct input/output token pricing.

Question 3

What is the optimal iteration limit?

Accepted Answer

The limit is where the marginal cost per additional iteration exceeds 20% of the total cost so far, indicating diminishing returns.
