It's referenced by competing guard-model releases (including Shieldstral) as a comparison point outside of each vendor's own internal test sets. ## At a Glance **What it tests:** Safety classification accuracy against Alibaba's own evaluation methodology for the Qwen3Guard family of guard models. **Why it matters:** As a benchmark released alongside a specific guard model family, Qwen3GuardTest gives an independent-vendor cross-check — seeing how a competing classifier performs on Alibaba's own test set complements evaluation on more neutral, third-party benchmarks like WildGuardTest. **Known limitations:** Full test set composition and exact size are not broken out in public third-party comparisons; treat scores here as directionally useful rather than precisely reproducible without access to Alibaba's original evaluation harness. ## What Qwen3GuardTest Measures Qwen3Guard is Alibaba's guard-model family (available in Gen and Stream variants across multiple sizes) built for real-time and generation-time safety classification. Qwen3GuardTest is the evaluation methodology and held-out data referenced in the Qwen3Guard technical report, used both to validate Qwen3Guard itself and, increasingly, as a cross-vendor comparison benchmark for other safety classifiers such as Shieldstral. ## Benchmark Specifications | Field | Value | |---|---| | Task category | Safety / content moderation | | Metric | F1 score (%) | | Created by | Qwen Team (Alibaba) | | Paper | [Qwen3Guard Technical Report (arXiv 2510.14276)](https://arxiv.org/abs/2510.14276) | | GitHub | [QwenLM/Qwen3Guard](https://github.com/QwenLM/Qwen3Guard) | | License | Apache 2.0 | ## How Qwen3GuardTest Is Scored Classifiers are scored as F1 against Alibaba's held-out labeled evaluation set, following the methodology described in the Qwen3Guard technical report. ## State-of-the-Art Results Scores from the Shieldstral model card (Mistral AI, August 2026).

What is Qwen3GuardTest?

Qwen3GuardTest is Alibaba's held-out safety evaluation benchmark from the Qwen3Guard technical report, used to validate the Qwen3Guard model family and increasingly cited by competing guard models for comparison.

Why does Qwen3Guard-8B score highest here?

This is Alibaba's own vendor-released evaluation set for the Qwen3Guard family, so some home-court advantage is expected relative to neutral third-party benchmarks.

Who created Qwen3GuardTest?

The Qwen Team at Alibaba, published in the Qwen3Guard technical report (2025).
