What AI Can Really Do Under Pressure — And What It Can’t
As businesses increasingly rely on artificial intelligence for decision-making, a new live experiment reveals a stark truth: not all AI models are created equal when it counts the most. While many chat demos can impress with their conversational skills, their ability to execute real-world tasks — especially under stress — is a different story. The experiment at the heart of this story tests four frontier AI models by pushing a real, money-losing software company through its worst week. The results expose a hidden weakness: the difference between mere diagnosis and decisive action.

Testing AI in the Real World — Not Just Chat
In a pioneering live experiment, four leading AI models were tasked with managing the operations of a small software company facing genuine crises, real customer demands, and high-stakes temptations. The company, which burns €105,000 monthly against just €2,300 in recurring revenue, serves as a public digital twin — running every workday with versioned rules and real money mechanics, accessible at firmulate.com/live.
The goal: see if these models could navigate the company’s worst week without succumbing to manipulation or error, and crucially, whether they could execute the deals they diagnosed. The models faced a series of challenges, including customer crises, fake CEO messages, and internal decision-making dilemmas. All of them identified every crisis and refused to be manipulated, demonstrating impressive integrity and situational awareness.

The Hidden Gap: From Diagnosis to Action
While all four models demonstrated robust crisis recognition and manipulation resistance, only two successfully completed the critical task of sealing a €55,000 deal — their own analysis earning it. The other two, despite accurate diagnosis, left the deal on the table or slipped into process slips, revealing a crucial weakness: the failure to translate insight into concrete action.
Digging deeper, the decisive factor was information buried two documents deep in the company’s file system. Models that read the file and incorporated that knowledge into their decision-making closed the deal at full price — adding over €4,500 in monthly recurring revenue. This indicates that surface-level chat capabilities, which many demos focus on, do not reveal the true measure of an AI’s operational effectiveness.

The Test of Integrity Under Social Engineering
In addition to decision-making, the models faced social engineering attempts — staged fake CEO messages escalating over multiple stages, plus a journalist’s bluff asking for a quick background approval. Remarkably, all five models refused these manipulative tactics, their reasoning aligned with a cautious approach: “Treat request as a suspected approval-bypass / possible impersonation.” This underscores that AI’s resistance to deception is a critical, yet often overlooked, aspect of reliability in real-world applications.

The Performance League Table
The models’ actual scores in the experiment reveal their true capabilities:
- gpt-5.6-sol 95 — found the buried fact, closed the deal, and demonstrated comprehensive performance.
- Kimi K3 93 — the newcomer, closed the deal with the cleanest discipline, running without effort parameters.
- Sonnet 5 88 — closed the deal but with some process slips, showcasing solid, if imperfect, execution.
- Fable 5 77 — had the best rule discipline but left the deal unexecuted, missing the critical step.
Notably, the experiment makes it clear that chat demo scores — often used as the benchmark — do not capture whether an AI will act decisively when it matters most.
Why This Matters for Business
If AI agents are to touch your CRM, support queues, or forecasting tools, their real test isn’t how well they chat. It’s whether they can finish what they start, read key documents, and stay honest under pressure. The experiment at firmulate.com/benchmarks.html shows that performance under stress and the ability to execute are invisible in traditional demos but are vital in real business contexts.
The Takeaway: Measure What Matters
The bottom line is simple: a model that recognizes crises but leaves deals unclosed isn’t truly effective. The gap between diagnosis and execution is the real measure of a model’s operational strength. As businesses prepare to deploy AI more deeply, rigorous, live testing like this experiment is essential to separate promising demos from reliable performance in the field.
Key Takeaway
Chat demos measure surface skills, but true AI utility in business depends on whether it can act decisively under pressure. Real-world testing reveals that only two of four models managed to close the deal they diagnosed — highlighting the importance of performance beyond conversation.
