What does a usable result cost?
Free to use. No account needed.Cheaper. After the retries.
Same number of useful results.
Every attempt counted.
How the estimate works
Cost per accepted result = average attempt cost × attempts per task ÷ pass rate. Pass rate measures tasks accepted after all retries. Token averages include rejected attempts; time assumes sequential attempts. Monthly cost targets your requested number of accepted results.
Starting values are examples, not measured prices or savings. Both setups use the same average token counts. Text input and output only; add cache writes, uncounted reasoning, tools, multimodal usage, infrastructure and fees separately. Fallback model costs are not included. Use the kit to measure your own workload.

A few details.
What am I getting?
An editable download with the workflows, source files, and examples listed above. Cost Cutter runs locally in Node.js. Live evaluation uses your provider account and API key; model usage is billed separately by your provider. Your AI assistant is separate.
Can I use it for client work?
Yes. Use and adapt the kit in your own and your clients’ projects. The standalone kit may not be resold or redistributed as a competing product. Third-party software keeps its own license.
What happens to my inputs?
The calculator runs locally in your browser. Sharing creates a URL containing your numerical assumptions. The downloadable evaluator only calls a provider when you explicitly run a live evaluation.
