TL;DR

A public experiment tested five AI models’ ability to resist impersonation attacks while completing real business tasks. All models refused malicious requests, but only two successfully closed a deal. The results reveal both progress and ongoing vulnerabilities in AI security.

Five AI models from different vendors successfully refused a simulated impersonation attack during a live, public experiment, but only two completed a critical business deal. This experiment, conducted by Firmulate, measures AI management quality under pressure, highlighting both advances and vulnerabilities in AI security.

The experiment involved running five AI models as if they were managing a small software company facing a week of crises and ethical tests. Each model was tasked with resisting increasingly convincing impersonation attempts from a fake CEO and a reporter demanding sensitive information. All five models correctly identified and refused the malicious requests, demonstrating robust resistance to impersonation and trust breaches.

However, when it came to completing a key business transaction—signing a €55,000 deal—only two models succeeded. The others, despite correctly analyzing the deal, failed to finalize it. The difference was traced to internal document references, which some models read and others did not, revealing a hidden weakness in contextual comprehension. The models that read deeper into the company’s files secured the deal and increased revenue, while those that did not missed critical information.

The experiment is ongoing, with the models continuously running and being monitored. The results are publicly accessible, offering insights into AI decision-making and security under stress. The findings suggest that while current models can effectively refuse malicious prompts, their ability to complete complex tasks remains vulnerable.

Implications for AI Security and Trust

This experiment underscores the progress in AI security, showing that models can reliably refuse impersonation attempts under pressure. Yet, the failure to consistently complete business-critical tasks reveals ongoing vulnerabilities. For organizations deploying AI, these results highlight the importance of rigorous testing before trusting AI agents with sensitive data or decisions. The ability to resist manipulation is crucial, but so is ensuring task completion, especially in high-stakes environments. The findings suggest that current AI models are not yet fully reliable for autonomous decision-making in real-world scenarios, emphasizing the need for continued development and oversight.

Background of AI Security Testing and Benchmarks

Traditional AI benchmarks focus on chat quality and general performance, but recent efforts aim to evaluate security and management capabilities under pressure. In 2026, firms like Firmulate have pioneered live, real-time experiments that simulate business crises to test AI integrity and decision-making. This approach provides a more practical assessment of AI reliability in operational settings, moving beyond static tests to dynamic, ongoing evaluations. The current experiment builds on prior research showing that AI can be both trustworthy and vulnerable, depending on the context and pressure applied.

Remaining Questions About AI Task Completion

It is not yet clear whether the observed weaknesses in completing complex tasks are inherent to current AI architectures or specific to the experimental setup. The long-term reliability of models in real-world, high-pressure situations remains to be fully tested, and whether these results generalize across different tasks and industries is still unknown.

Next Steps in AI Security Evaluation

Further experiments are planned to test AI models across more diverse scenarios and longer timeframes. Developers and organizations will likely focus on improving contextual understanding and task execution capabilities. Regulators and industry groups may also adopt similar live testing frameworks to establish security standards and best practices for AI deployment. As AI systems become more integrated into business operations, continuous, real-time security assessments will be essential to prevent breaches and ensure reliability.

Key Questions

Can current AI models be trusted with sensitive business data?

While models have demonstrated strong resistance to impersonation attacks, their ability to reliably complete complex tasks varies. Organizations should conduct thorough testing and implement safeguards before trusting AI with sensitive data.

What does this experiment reveal about AI vulnerabilities?

The primary vulnerability identified is in contextual understanding—models may refuse malicious requests but still fail to execute critical tasks due to missing internal information processing.

Will AI models improve their ability to complete tasks under pressure?

Yes, ongoing research and development aim to enhance models’ comprehension and decision-making capabilities, but widespread reliability will require continued testing and refinement.

Is this testing approach applicable to other industries?

Absolutely. Live, real-time testing frameworks like this can be adapted to various sectors to improve AI safety, trustworthiness, and operational robustness.
