Giskard

AI quality testing for bias, drift, and vulnerabilities

freemiumopen sourceupdated Aug 16, 2026

Giskard is an open-source testing framework for evaluating AI model quality, detecting bias, data drift, and security vulnerabilities. It provides automated test generation for LLMs and tabular models, scanning for issues like hallucination, prompt injection susceptibility, stereotypical outputs, and data leakage. Integrates with CI/CD pipelines for continuous model validation before deployment.

Giskard provides automated quality testing for AI models, covering the unique failure modes that traditional software testing cannot address. For LLM applications, it scans for hallucination patterns, prompt injection vulnerabilities, stereotypical or biased outputs, sensitive information disclosure, and robustness to input perturbations. For tabular ML models, it detects data drift, performance degradation across subpopulations, and feature importance instabilities that could indicate reliability issues in production.

The framework generates test suites automatically based on model analysis, producing comprehensive coverage of potential failure modes without requiring manual test case authoring. Tests can be integrated into CI/CD pipelines to gate model deployments on quality checks, preventing regressions when models are retrained or prompts are modified. Giskard also provides a collaborative hub where teams can review test results, annotate false positives, and track model quality metrics over time across versions.

Giskard is open-source with a Python-first API that integrates with popular ML frameworks including Hugging Face, LangChain, scikit-learn, and PyTorch. The project maintains an active community contributing test templates and model-specific scanning rules. For organizations that need to demonstrate AI model quality and safety — whether for regulatory compliance, internal governance, or customer trust — Giskard provides the testing infrastructure that catches AI-specific quality issues before they reach production.

Comparisons

DeepEval vs Giskard — LLM Unit Tests or AI Risk Scanning

DeepEval and Giskard both test AI systems, but they start from different failure modes. DeepEval is the sharper default when an engineering team wants pytest-style regression tests for LLM apps, while Giskard is stronger when model risk, bias, and vulnerability scanning are the central requirement.
