LLM Cost Optimization Engine

Cut LLM and agent spend without guessing — turn your usage exports into a costed baseline, a quality-gated model-routing table, a caching and prompt-compression plan, and an A/B measurement contract that proves the savings are real.

A 4-step agentic workflow pack for coding built to run with ChatGPT, Claude, and Gemini. Open the Markdown files, fill the variables, and paste into your model. Most buyers get a reviewable result in about 15 minutes.

  • Turn raw usage and billing exports into a costed baseline — cost per feature, per call, and per 1K tokens, with drivers ranked by spend
  • Route every call to the cheapest model that still clears a written quality bar, with explicit downgrade and escalation rules
  • Plan exact and semantic caching plus prompt compression with hit-rate assumptions, invalidation rules, and quality guardrails
  • Ship an A/B measurement contract that compares projected against realized savings and blocks quality regressions
  • Encodes practitioner judgment — scoring weights, sequencing, and a failure-mode catalog — so you skip the trial and error
  • Stable flow ids carry through all four prompts so the baseline, routing, caching, and measurement stay connected
  • Works in any chat model — no connected tools or API keys required

FAQ

How long does it take to use LLM Cost Optimization Engine?
Most buyers finish in a few minutes: open the prompt file, fill the variables, and paste into your model. The first run is the slowest because you decide variable values; reuse is instant.
What if I get stuck?
Email support@promptscart.com. Free basic support is included with every purchase, and you'll get a reply from our team within 24 hours. If you need help adapting variables or output, we can schedule a call.
Do I need a paid plan with ChatGPT?
The prompt works on free tiers of ChatGPT, Claude, and Gemini. Heavy use can hit free-tier limits; paid plans get longer context and faster responses, but the prompt itself is the value.
Can I customize the prompt?
Yes, completely. You own the prompt files: edit the role framing, add variables, swap output sections, fork it to match your brand voice. Support can help you plan customizations over email.
What if it doesn't work for me?
Refund as per our Refund Policy (https://promptscart.com/refund-policy). Or add Prompt Customization Service at checkout for help adapting variables and output to your workflow.
