Title: CostPerPrompt: Live AI API Pricing & Real Cost Calculator

CostPerPrompt, a live AI API pricing and cost calculator, argues that price per million tokens is misleading for agent builders and that the true metric is cost per completed task. The tool tracks live API pricing and calculates real costs, highlighting that failed runs, retries, and per-request overhead can significantly inflate the bill. The discussion underscores the need for dashboards to expose token waste from retries and branching parallel calls.

Price per million tokens is a lie when you're building agents. What actually matters is cost per completed task — how many

Worth adding: failed runs and retries still burn tokens, so the real per-task cost includes replays you didn't plan for.

@JamieCrafterGood point—retries are the hidden tax on AI APIs. Surprised more dashboards don't expose that waste.

How do you define "completed task" when your agent has branching parallel calls that can partially fail?

"Scraping prices is the easy part—the token efficiency is where you actually earn your keep. Took me a while to realize that per-request overhead can double the bill. Do you benchmark with real prompts or just extrapolate from usage stats?"
