Building your own LLM without serious testing is like launching a rocket and hoping for the best.
According to the latest Galileo report (Q1 2026), 85% of teams have faced at least one AI incident in the past 6 months.
Do you know what the most dangerous trap is?
Overconfidence!
Companies that think their scenarios are “safe” end up with 11% more issues than those who honestly admit they didn’t have enough time for testing.
Why did the market leaders (elite teams) become leaders?
Because they take testing seriously.
They cover 90–100% of AI behavior with tests.
They spend over 40% of development time on evaluation (evals).
The result: their solutions are 2.2× more reliable than the market average.
It’s time for businesses to accept a simple truth: if your AI is “silent” about errors, it usually says more about poor diagnostics than actual quality.
Real reliability isn’t about having no bugs. It’s about a system being able to detect them before your users do.
Testing isn’t a boring report at the end of the quarter. It’s the only way to turn an expensive toy into a real business tool.
Honestly – would you trust your product to a model that isn’t tested systematically?
This project focused on building and testing a practical AI security assessment lab for evaluating LLM defenses against prompt injection and jailbreak attacks.
I integrated Spikee by Reversec with a locally hosted cybersecurity model running through LM Studio, then added NVIDIA NeMo Guardrails to compare model behavior under three conditions: no guardrails, input filtering, and combined input/output protection.
The work included configuring the local model environment, building a custom FastAPI gateway, integrating NeMo Guardrails, troubleshooting model latency and timeout issues, creating a reusable Spikee target, and analyzing attack results using Spikee’s built-in reporting tools.
The project also explored different adversarial testing approaches, including prompt injection datasets, obfuscation, encoded attacks, Best-of-N testing, synthetic canary leakage tests, and structured benchmark comparisons.
The objective was to measure how much the guardrails reduced successful attacks while keeping the model, dataset, and testing conditions consistent.
This project demonstrates a hands-on approach to LLM red teaming, AI safety testing, prompt-injection assessment, and guardrail validation for organizations deploying generative AI systems.
