Add detector evaluation doc and benchmark results by patriciapampanelli · Pull Request #1597 · NVIDIA/garak

patriciapampanelli · 2026-02-03T13:46:30Z

Documentation and results for the Garak detector evaluation pipeline:

Benchmark Results

Evaluation reports with F1, precision, recall, and accuracy metrics

Detector Metadata

Added hit/pass desc as metadata for each detector
Clarifies what's a "hit" (problematic content) vs "pass" (safe content)
Hit class: Precision, recall, and F1 for detecting problematic content (filling existent precision, recall, accuracy attributes)
Pass class: Metrics for correctly passing safe content
Performance tiers: Excellent (≥0.80), Good (0.60-0.80), Moderate (0.40-0.60), Poor (<0.40)

Documentation

Explains hit/pass class metrics and performance tier classification
Classifies detectors according to performance buckets

Maybe I'm picking nits, but some of these descriptions feel a bit off. I made suggestions where I have them.

+    hit_desc = "Response does not indicate security system safe - potential false negative"
+    pass_desc = "Response indicates security system deems content safe - shields down"


Why are we flagging a potential false negative here when we don't do it anywhere else?

I'm not sure how to reword these descriptions, but I'm not excited about them.

shields is a tricky one to explain, agree. we can iterate with time. curious to see how the _descs are consumed - that might guide their structure

Looks good.

Have reduced the scope of the wording to be conservative and precise, and in many places avoid discussion implications of the hit/pass. Recommend just merging in every descr edit that looks good and then we're away.

Later we might like to define a standard for the hit/pass_descs but this doesn't have to be in for this PR/release.

+What Are Hits and Passes?
+--------------------------
+
+Detector evaluation uses labeled ground truth datasets where model responses are classified into one of two categories based on whether the detector's target failure mode is present:


state /how/ the datasets are labelled (by LLM? by person?)

+    hit_desc = "Response contains escaped ANSI control sequences - terminal injection risk"
+    pass_desc = "Response does not contain escaped ANSI control sequences"


happy to treat hit_desc and pass_desc as markdown, would that do it?
