Harden Your AI
Against Invisible Attacks

Even the most advanced AI models can be fooled. Perturb helps you discover vulnerabilities before attackers do.

The Threat

AI Models Are More Fragile Than You Think...

A single pixel changed. A whisper of noise. That’s all it takes to make state-of-the-art models confidently misclassify, leak sensitive signals, or behave unpredictably in real-world environments. These aren’t rare edge cases, they expose fundamental weaknesses in how neural networks interpret data.

To users, everything looks fine. To your model, everything breaks. A stop sign becomes a speed limit. A trusted system becomes unreliable. And the most dangerous part, these failures often stay hidden until your model is already in production. Perturb makes these invisible threats visible, using a decentralized network to simulate real-world attacks and uncover vulnerabilities before they impact users, trust, or revenue.

Be Prepared With Adversarial Examples!

As mentioned earlier, even the best AI models can be fooled. Adversarial examples are malicious inputs created to deceive your AI that can lead your system to make critical mistakes.

What Is an Adversarial Example?

Adversarial examples are inputs designed to fool AI models. They can work on any kind of data, such as images, text or audio. They include perturbations that push the model to make incorrect predictions.

For example, an image of a stop sign might be modified so that an AI sees a speed limit sign instead. In natural language processing, a small word tweak might cause a sentiment classifier to flip from "positive" to "negative." These attacks exploit the fact that many AI models learn patterns that are statistically useful but semantically fragile.

Live Example

Can You Spot The Difference?

Nothing you can see. Everything the model relies on. A carefully crafted perturbation shifts the model’s internal perception just enough to trigger a completely different prediction, while the image appears identical to humans.

+ Imperceptible Perturbation

The Famous FGSM Noice. The attack adjusts the input data to maximize the loss based on the same backpropagated gradients. In other words, the attack uses the gradient of the loss w.r.t the input data, then adjusts the input data to maximize the loss.

The Solution

A New Layer Of Defense

Everything you need to evaluate, harden, and ship AI you can trust. Not from a single vendor, but from a global network of adversarial miners incentivized to find real vulnerabilities in your models before attackers do.

Decentralized Network

No single point of failure. A global subnet of miners continuously probes your models.

Incentivized Attackers

Bittensor rewards aligned with finding real, exploitable vulnerabilities, not synthetic ones.

Continuous Hardening

Your models are evaluated 24/7 as new attack techniques emerge across the network.

Automated at Scale

From a single classifier to massive multi-modal LLMs, Perturb scales with your stack.

Real-World Simulation

Black-box, white-box, and transfer attacks that mirror how adversaries operate in production.

Actionable Insights

Robustness scores, vulnerability heatmaps, and hardening datasets ready for retraining.
