Fine-Tune vs RAG vs Prompt Decision Engine

Settle the fine-tune vs RAG vs prompt-engineering question with a weighted cost/latency/maintenance scorecard, a reversibility and failure-mode read, and a decision memo your team will actually approve.

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 12 minutes.

  • Frame fine-tune, RAG, and prompt-engineering as concrete, comparable options
  • Score every path on a weighted cost, latency, quality, and maintenance model
  • Expose reversibility, lock-in, and the failure modes each path is prone to
  • Get a per-path proof-of-concept protocol with kill criteria before you commit
  • Ship a decision memo with rationale, risks, and rollback that stakeholders approve
  • Replace hallway debates with a repeatable, auditable architecture decision

FAQ

How long does it take to use Fine-Tune vs RAG vs Prompt Decision 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?

Do I need a paid plan with ChatGPT?

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.
