WonderCheck: Detecting AI Degradation in Prod

Production AI rarely fails all at once. It slips as a response sounds slightly off, a behavior that looked solid during launch reviews starts to bend after a model update or a system prompt tweak, or a  guardrail triggers when you don’t expect (or doesn’t trigger when expected.) None of it feels urgent on its own, but together those changes quietly reshape how an AI system behaves in the real world.

Most operations teams only see these shifts after users report them or complain about them on social media, or when incidents surface. By then, the question is no longer what changed, but how long it went unnoticed.

WonderCheck is designed to catch those moments earlier. It enables ongoing evaluation of live GenAI and agentic systems, helping teams catch drift, regressions, and emerging threats early, before subtle changes turn into real risk.

Why Production Testing Needs A Different Mindset

Production change is also hard to evaluate because it doesn’t come from one place. Behavior can shift due to model upgrades, prompt edits, policy tuning, or entirely new usage patterns that emerge only at scale. These inputs interact in ways that are difficult to predict and even harder to reason about long after the fact.

As a result, teams often lack a clear baseline for what “normal” looks like in production. When something feels off, it’s not always obvious whether the cause is slow drift, a regression from a recent change, or a new vulnerability emerging from real-world use. Without consistent evaluation, these signals blur together, making it harder to prioritize fixes and easier for risk to persist unnoticed.

Production testing has to reflect that reality. It has to be ongoing, adversarial, and grounded in how systems are actually being used.

WonderCheck runs automated, policy driven adversarial tests against live systems on a regularly scheduled or on demand basis. Instead of asking whether a system passed a checklist, it asks how behavior has changed since the last evaluation, where new vulnerabilities may be emerging, and which shifts matter most right now.

Detecting Drift Before It Becomes Damage

What makes drift one of the hardest challenges in production is that it can come from many places. Model updates. Fine tuning. New prompts introduced by product teams. Changes in user behavior that no one anticipated.

WonderCheck evaluates production systems to detect these changes early. By comparing results over time, teams can see when behavior starts to diverge from expected patterns, even if outputs still look acceptable at a glance. This same evaluation also reveals regressions, where previously mitigated issues return, and emerging vulnerabilities that were never present in earlier testing.

This matters because regressions often reintroduce known risks. A safety issue fixed during development can quietly return after a model refresh. A platform-native guardrail that once performed well may lose accuracy as usage shifts. WonderCheck surfaces these changes with clear signals and prioritization, so teams know what needs attention first instead of chasing noise.

Validating Guardrails In The Real World

Guardrails play a critical role in protecting users and systems, but they’re not set and forget. Platform-native and third party guardrails can struggle with calibration, especially as systems scale and diversify.

WonderCheck evaluates guardrail performance directly in production. It helps identify false positives that block safe or useful interactions, as well as false negatives that allow risky behavior through. This gives teams concrete evidence of where protections are too aggressive, too permissive, or misaligned with policy.

For Responsible AI and security teams, this kind of validation is essential. It turns guardrails from assumptions into measurable controls, backed by data that reflects real usage rather than test cases.

Understanding The Impact Of Policy Changes

Policy updates are often necessary, but they carry risk. A small change to enforcement thresholds or safety rules can have outsized effects on production behavior.

WonderCheck allows teams to assess the impact of proposed WonderFence policy changes before they’re deployed. By running policy driven tests against live systems, teams can see how behavior would shift and catch unintended consequences early.

This reduces guesswork and makes governance more operational. Policies stop living only in documents and start functioning as part of an active system that can be tested, measured, and improved over time.

Built On Real Adversarial Intelligence

At the core of WonderCheck is Rabbit Hole, Alice’s adversarial intelligence engine. It’s informed by years of global trust, safety, and security research, and billions of analyzed toxic, deceptive, and manipulative data samples.

This foundation means WonderCheck isn’t limited to scripted attacks or theoretical risks. Its evaluations reflect real-world misuse patterns and emerging threats, giving teams insight into how systems may fail in practice, not just in theory.

As risk landscapes evolve, the intelligence behind WonderCheck evolves with them. That context is what allows teams to stay ahead of issues instead of reacting after the fact.

Designed To Fit Real Workflows

Production testing only works if teams can actually run it. WonderCheck integrates into existing CI/CD pipelines, evaluation cycles, and governance programs without disrupting development velocity or operational workflows.

Tests can be scheduled, triggered on demand, or aligned with release cycles. Results are delivered as clear, prioritized insights that help engineers, product leaders, and governance teams focus on the changes that matter most. Findings are surfaced through structured reports and dashboards that map issues to severity and policy context, making it easy for teams to act without digging through raw test output.

For compliance and risk teams, WonderCheck also supports alignment with frameworks like the EU AI Act, ISO 42001, NIST, and OWASP. Production evaluation details and outcomes become easier to document and demonstrate as part of a proactive, ongoing governance approach.

Sustaining Trust As AI Evolves

AI systems will keep changing. That’s part of what makes them valuable. The challenge is making sure trust keeps pace with that change.

WonderCheck helps teams move from reactive production monitoring to proactive evaluation. By continuously testing live systems, catching drift and regressions, and surfacing emerging vulnerabilities early, it gives organizations a clearer understanding of how AI behavior evolves over time.

Trust isn’t something you earn once at launch. It’s something you earn and maintain, iteration by iteration. WonderCheck is built to support that reality, so teams can operate AI systems with confidence long after they go live.
