How to Buy a Prompt Library or AI Asset
The buyer's guide for AI assets — prompt libraries, datasets, fine-tuned models, agents and evals — with pricing benchmarks.
TL;DR
Asset buys close in days, not weeks. Verify provenance, get a signed license transfer, and test the asset against your own eval before wiring funds.
The three verification steps
Provenance (who created it and how), performance (on your data, not the seller's), and rights (can it be resold, can you modify it).
Frequently asked questions
What's a fair price for a prompt library?
$200–$5,000 for a curated set with proven revenue attribution. Anything above that needs enterprise-scale evidence.
