# How much does it cost to run a classifier on every trace?

Classifiers are included in Tessary's [published price](/#pricing): $0.001 per trace, with a $100 monthly minimum. At 1 million traces a month that is $1,000, and every one of those traces goes through the full classifier layer. There is no separate meter for classification.

The rate can stay flat because the always-on checks have negligible per-trace cost. The expensive LLM judgment only reads the findings classifiers write, which is a small slice of traffic, so the heavy cost tracks how often the cheap checks fire rather than how much you serve.

One trace is one agent turn: the user's message, your agent's full response, and every tool call in between.
