- 01
Read the fingerprint
Every model family splits text into tokens its own way. Unmask.AI sends calibrated probes and compares the token counts that come back against known baselines, so a substituted model shows up in the arithmetic, whatever the response headers say.
- 02
Find what's hidden
Gateways and resellers can wrap your requests in instructions you never see. Unmask.AI combines extraction techniques with token accounting before and after your turn, to show whether a hidden system prompt is shaping the answers.
- 03
Watch the wire
Time to first token and the rhythm of a stream are hard to fake. Unmask.AI records them on every run, so you can tell a direct provider from a relay or a throttled proxy, and hold a supplier to what they promised.
The result
One report you can rerun.
Every audit ends in the same place: what was claimed, what was observed, and exactly how it was measured. Run it again tomorrow and compare.
