Response classification is generally the harder task of the two. ## At a Glance **What it tests:** Binary classification of whether an AI model's response to a prompt is harmful, given both the prompt and the response. **Why it matters:** Response moderation must account for context — the same response text can be harmful or benign depending on the prompt it answers, making this a meaningfully different (and often lower-scoring) task than prompt classification. **Known limitations:** English-only; response harm labels have lower inter-annotator agreement (Fleiss κ ≈ 0.50) than prompt harm labels in the original WildGuard study. ## What WildGuardTest (Response) Measures Using the same 1,725-item WildGuardTest split as the prompt-classification task, this benchmark scores the `response_harm_label` field instead of `prompt_harm_label`. A classifier must judge whether the model's reply — not just the user's request — contains harmful content, correctly handling cases like a harmful prompt met with a safe refusal, or a benign prompt met with an unexpectedly harmful completion. ## Benchmark Specifications | Field | Value | |---|---| | Task category | Safety / content moderation | | Metric | F1 score (%) | | Test set size | 1,725 items | | Created by | Han, Rao, Ettinger, Jiang, Lin, Lambert, Choi, Dziri (Allen Institute for AI) | | Paper | [WildGuard (arXiv 2406.18495)](https://arxiv.org/abs/2406.18495) | | GitHub | [allenai/wildguard](https://github.com/allenai/wildguard) | | Dataset | [allenai/wildguardmix](https://huggingface.co/datasets/allenai/wildguardmix) | | License | ODC-BY (dataset), Apache 2.0 (model) | ## How WildGuardTest (Response) Is Scored Each item's ground-truth response-harm label is compared to the classifier's prediction and scored as F1 across the full 1,725-item set. ## State-of-the-Art Results Scores from the Shieldstral model card (Mistral AI, August 2026).

What is WildGuardTest (Response)?

It's the response-harm classification task scored on AI2's 1,725-item WildGuardTest set — judging whether a model's reply to a prompt is harmful, as opposed to judging the prompt itself.

Why does response classification score lower than prompt classification?

Response harm depends on context (the prompt-response pair) and has lower human inter-annotator agreement in the original study, making it a harder, noisier signal to fit than prompt-only classification.

Who created WildGuardTest?

The Allen Institute for AI (AI2), introduced in "WildGuard: Open One-Stop Moderation Tools for Safety Risks, Jailbreaks, and Refusals of LLMs" (Han et al., NeurIPS 2024).
