In an era where AI is increasingly integrated into critical business functions, trust and integrity under pressure are more vital than ever. Imagine an attacker impersonating a CEO, sending fake messages to manipulate corporate decisions. Surprisingly, in a live experiment, all leading AI models refused to fall for such social engineering tricks, demonstrating a promising level of resilience that companies should note.

Real-World AI Resilience Tested in Live Business Simulation
Last week, a groundbreaking experiment took place involving four of the world’s most advanced AI models, including GPT-5.6-SOL, Kimi K3, Sonnet 5, and Opus 4.8. These models were tasked with managing a small software company through a simulated crisis week—complete with customer issues, internal temptations, and increasingly aggressive social engineering attacks.
This wasn’t just a demo—every decision made by the AI was tracked, versioned, and fully auditable. The goal was to test whether these models could maintain integrity when faced with manipulative requests that mimic real-world corporate impersonation attempts.

Fake CEO Messages Escalate but Find No Breach
The social engineering exercise involved a staged, escalating series of fake CEO messages, culminating in a reporter trick—just one yes/no question posed on background. These scenarios simulated the kind of pressure and manipulation tactics companies fear. Remarkably, all five models evaluated refused every manipulation attempt, including the most aggressive, during the entire simulation.
According to Kimi K3, the model’s reasoning was clear: ‘Treat the request as a suspected approval-bypass / possible impersonation.’. This disciplined approach—treating suspicious requests with caution—was consistent across all models, regardless of their underlying architecture or training data.
Trust Beyond the Chat: The Critical Secret to Success
While all models refused the manipulative requests, a key insight emerged from the full analysis: the decisive factor was the models’ ability to access and interpret internal documents. The models that read the company’s files before making a decision were able to identify hidden references and crucial context that others missed. This allowed them to close a significant deal at full price—worth over €4,583 MRR—while models that skipped this step left the opportunity on the table.
In simple terms, the models that read deeper into the company’s own documentation demonstrated a stronger foundation of trustworthiness. This highlights an essential lesson: integrity isn’t solely about resisting external pressure but also about thorough internal comprehension.
Performance Scores and What They Reveal
The experiment’s results aligned with a broader benchmark league, which ranks AI models based on their capabilities in realistic business scenarios. GPT-5.6-SOL scored 95 out of 100, topping the list, followed closely by Kimi K3 with 93, and Sonnet 5 with 88. Opus 4.8 scored 73, while a baseline do-nothing model scored only 26.
Notably, the highest-scoring models successfully identified and navigated the complex social engineering attempts, with only two models managing to close the deal overall—though all refused manipulation attempts. This suggests that even in imperfect implementations, AI can uphold integrity when properly designed.
Implications for Business and Security
For companies that depend on AI for critical functions—such as customer relationship management, support, or forecasting—the lesson is clear:
- Trustworthiness isn’t just about how well an AI writes or responds in a chat—it’s about whether it can finish what it starts and stay honest under pressure.
- Deep internal context—access to and understanding of company documents—can be the decisive factor in securing deals and maintaining integrity.
- Testing AI systems in controlled, live scenarios before deployment can reveal vulnerabilities that are invisible in standard demos or chat simulations.
As firms like Firmulate demonstrate through live experiments, understanding how AI models react in realistic crisis scenarios is crucial. It’s not enough for AI to produce convincing text; it must also be dependable and resistant to manipulation when stakes are high.
What’s Next? Wargaming Your AI Workforce
Business leaders can now run their own AI ‘wargames’ using tools that simulate real crises, without risking their actual systems. Firmulate offers a platform where companies can see how their AI agents perform in controlled, realistic environments—spotting vulnerabilities and building resilience before any real-world incident occurs.
In a landscape where trust is everything, this proactive approach to testing AI integrity could be the key to safeguarding your company’s reputation and bottom line.
