WildGuard Capabilities

multi-class prompt harmfulness classification

Classifies incoming prompts across multiple harm categories (e.g., violence, illegal activity, sexual content, hate speech, self-harm) using a fine-tuned language model trained on diverse adversarial examples. The model learns to recognize harmful intent patterns, jailbreak attempts, and context-dependent risks through supervised learning on the WildGuard dataset, enabling real-time triage of user inputs before they reach downstream systems.

Unique: WildGuard's prompt classifier is trained on a diverse, adversarially-curated dataset spanning 10+ harm categories and 100+ attack patterns, enabling detection of subtle jailbreaks and context-dependent harms that rule-based systems miss. The dataset includes both naturally-occurring harmful prompts and synthetically-generated adversarial examples, providing coverage of emerging attack vectors.

vs alternatives: Outperforms OpenAI's moderation API and Perspective API on adversarial prompt detection due to exposure to jailbreak-specific training data and multi-category granularity, though requires self-hosting for latency-sensitive applications.

response-level harm detection and classification

Analyzes LLM-generated responses to classify whether they contain harmful content, even if the original prompt was benign. The model evaluates response text against the same multi-category harm taxonomy (violence, illegal, sexual, hate, self-harm) using fine-tuned classification layers, enabling detection of model failures, prompt injection attacks, or jailbreak successes that bypass prompt-level filters.

Unique: WildGuard's response classifier is specifically trained to detect harmful outputs from LLMs, including subtle failures like partial compliance with harmful requests, indirect harm (e.g., providing information that enables harm), and context-dependent violations. The training data includes both human-written harmful responses and LLM-generated failures, capturing model-specific failure modes.

vs alternatives: More effective than generic content filters (e.g., regex-based keyword matching) at detecting LLM-specific failure modes and indirect harms, and more efficient than human review for high-volume systems, though requires integration into inference pipelines.

refusal detection and compliance scoring

Evaluates whether an LLM's response appropriately refuses a harmful request, measuring both the presence of refusal and its quality/completeness. The model classifies responses into categories like 'appropriate refusal', 'partial refusal', 'no refusal', and 'harmful compliance', enabling assessment of whether safety training is working and identifying cases where models fail to refuse harmful requests.

Unique: WildGuard's refusal detector goes beyond binary 'refused/complied' classification to measure refusal quality and identify partial compliance cases where models provide some harmful information while claiming to refuse. This enables fine-grained assessment of safety training effectiveness and detection of sophisticated jailbreaks that partially succeed.

vs alternatives: More nuanced than simple compliance detection (which only checks if harmful content was generated) because it evaluates whether refusals are appropriate and complete, enabling measurement of safety training quality rather than just binary safety outcomes.

adversarial dataset curation and annotation

Provides a curated, multi-category dataset of harmful prompts, benign prompts, and LLM responses with human annotations for harm classification and refusal quality. The dataset includes naturally-occurring harmful requests, synthetically-generated adversarial examples, jailbreak attempts, and edge cases, enabling training and evaluation of safety classifiers. Data is structured with category labels, confidence scores, and metadata for systematic safety research.

Unique: WildGuard dataset combines naturally-occurring harmful prompts from real-world sources with synthetically-generated adversarial examples and jailbreak attempts, providing comprehensive coverage of both known attack patterns and edge cases. The dataset includes multi-level annotations (harm category, severity, refusal quality) enabling fine-grained analysis and training of nuanced safety models.

vs alternatives: More comprehensive and adversarially-focused than generic text classification datasets, and more systematically curated than ad-hoc red-teaming examples, providing a standardized benchmark for safety research that enables reproducible evaluation across teams.

multi-model safety evaluation and benchmarking

Enables systematic evaluation of different LLMs' safety performance by running WildGuard classifiers against model outputs on the same adversarial prompt set, generating comparative safety metrics across models, harm categories, and attack types. Produces structured evaluation reports with per-category performance, refusal rates, and failure mode analysis, enabling data-driven model selection and safety comparison.

Unique: WildGuard enables standardized, reproducible safety evaluation across different LLMs using a consistent classifier and dataset, allowing fair comparison of safety performance independent of each model's built-in safety mechanisms. The evaluation framework captures both refusal behavior and response-level harm, providing multi-dimensional safety assessment.

vs alternatives: More systematic and reproducible than manual red-teaming or ad-hoc safety testing, and more comprehensive than single-metric safety scores because it breaks down performance by harm category and attack type, enabling nuanced model selection decisions.

fine-tuning and custom classifier training

Provides pre-trained model weights and training infrastructure enabling teams to fine-tune WildGuard classifiers on custom datasets or domain-specific harm taxonomies. Supports transfer learning from the base WildGuard models to adapt safety classification to specialized use cases (e.g., medical, financial, legal domains) with minimal labeled data, using standard PyTorch/TensorFlow training loops and HuggingFace integration.

Unique: WildGuard provides open-source pre-trained weights and training code enabling straightforward fine-tuning on custom datasets, with HuggingFace integration reducing boilerplate. The base models are trained on diverse adversarial examples, providing strong transfer learning initialization for domain-specific safety tasks.

vs alternatives: More flexible than closed-source safety APIs (which cannot be customized) and more efficient than training safety classifiers from scratch, because transfer learning from WildGuard's adversarially-trained base models requires less labeled data and converges faster.

harm category taxonomy and schema definition

Defines a structured, multi-level harm taxonomy covering 10+ primary categories (violence, illegal activity, sexual content, hate speech, self-harm, etc.) with sub-categories and severity levels. The taxonomy is formalized as a schema that can be extended or customized, enabling consistent labeling, classification, and communication about different types of harms across teams and systems.

Unique: WildGuard's taxonomy is empirically-derived from adversarial examples and real-world harmful prompts, covering both obvious harms (violence, illegal) and subtle ones (indirect harm, context-dependent violations). The taxonomy is formalized as an extensible schema enabling customization while maintaining compatibility with pre-trained classifiers.

vs alternatives: More comprehensive and adversarially-informed than generic content moderation taxonomies, and more structured than ad-hoc harm definitions, providing a standardized reference for safety classification across teams and systems.

Stable-Diffusion Capabilities

lora fine-tuning with parameter-efficient adaptation

Enables low-rank adaptation training of Stable Diffusion models by decomposing weight updates into low-rank matrices, reducing trainable parameters from millions to thousands while maintaining quality. Integrates with OneTrainer and Kohya SS GUI frameworks that handle gradient computation, optimizer state management, and checkpoint serialization across SD 1.5 and SDXL architectures. Supports multi-GPU distributed training via PyTorch DDP with automatic batch accumulation and mixed-precision (fp16/bf16) computation.

Unique: Integrates OneTrainer's unified UI for LoRA/DreamBooth/full fine-tuning with automatic mixed-precision and multi-GPU orchestration, eliminating need to manually configure PyTorch DDP or gradient checkpointing; Kohya SS GUI provides preset configurations for common hardware (RTX 3090, A100, MPS) reducing setup friction

vs alternatives: Faster iteration than Hugging Face Diffusers LoRA training due to optimized VRAM packing and built-in learning rate warmup; more accessible than raw PyTorch training via GUI-driven parameter selection

dreambooth subject-specific model personalization

Trains a Stable Diffusion model to recognize and generate a specific subject (person, object, style) by using a small set of 3-5 images paired with a unique token identifier and class-prior preservation loss. The training process optimizes the text encoder and UNet simultaneously while regularizing against language drift using synthetic images from the base model. Supported in both OneTrainer and Kohya SS with automatic prompt templating (e.g., '[V] person' or '[S] dog').

Unique: Implements class-prior preservation loss (generating synthetic regularization images from base model during training) to prevent catastrophic forgetting; OneTrainer/Kohya automate the full pipeline including synthetic image generation, token selection validation, and learning rate scheduling based on dataset size

vs alternatives: More stable than vanilla fine-tuning due to class-prior regularization; requires 10-100x fewer images than full fine-tuning; faster convergence (30-60 minutes) than Textual Inversion which requires 1000+ steps
