LLM Fingerprint Detector

Verifies which LLM an API is really serving, catching resellers that swap in a cheaper model.

Desktopfree

LLM Fingerprint Detector is a free tool that checks whether an LLM API is genuinely serving the model it claims, using a research-backed fingerprinting technique to catch resellers or gateways that quietly substitute a cheaper model. It's for developers paying for a specific LLM model through a third-party API who want proof they're actually getting it.
