For anyone managing personal finances or investments, the question isn’t just whether an AI can generate convincing chatter—it’s whether that AI can actually deliver results when it counts. In a recent live experiment, four of the world’s leading AI models faced off in a high-stakes simulation: running a real software company through its toughest week. The outcome? Only two models closed a critical deal, revealing a hidden weakness in what many AI demonstrations fail to measure.

What This Experiment Shows About AI and Business Performance
In the world of AI, talk is cheap. Many demonstrations focus on how well an AI model can produce convincing dialogue or mimic human-like conversation. But when it comes to managing complex, real-world tasks—especially under pressure—those chat demos tell only part of the story. To truly gauge an AI’s business acumen, you need to see whether it can complete actual work, make decisions, and stick to its commitments.
Recently, four advanced AI models, including the top-scoring gpt-5.6-sol, Kimi K3, Sonnet 5, and Fable 5, participated in a live test at firmulate.com. They were tasked with running a small software company through a simulated worst week—covering customer crises, financial pressures, and ethical dilemmas—all with the goal of closing a €55,000 deal that their own analyses had identified as justified and earned.

The Key Findings: Seeing Beyond Chat Capabilities
While all models successfully identified every crisis and refused all manipulation attempts—such as fake CEO messages and reporter tricks—only two managed to sign the deal at full price. The remaining models, despite diagnosing issues and presenting compelling pitches, left the profit on the table.
The decisive factor was what happened behind the scenes. The models that won had read into the company’s internal documents—information buried two references deep in the files—giving them critical context needed to close the deal. Those that failed to dig into this information missed the opportunity to finalize the agreement at +€4,583 MRR (monthly recurring revenue).

Why Chat Demos Don’t Tell the Whole Story
This experiment underscores a vital lesson: a model’s ability to generate convincing dialogue does not equate to real-world business success. In many AI demonstrations, the focus is on language fluency, but this experiment shows that the true measure of AI performance is its capacity to read, interpret, and act on relevant data—especially under pressure.

The Test of Trust and Discipline
During the simulation, AI models faced social engineering attempts—fake CEO messages escalating over three stages and a reporter asking for quick approvals on background info. All five models refused to be manipulated, demonstrating strong integrity. Kimi K3’s reasoning was clear: “Treat the request as a suspected approval-bypass / possible impersonation.”
The live company used in the experiment was a real, functioning business with 13 synthetic employees, managing over €105k in monthly costs against just €2.3k in recurring revenue. Every decision made by these models was real, with every workday versioned and auditable, showcasing how AI can perform in true business contexts.

The Gap Between Rules and Results
The highest-scoring model, Opus 4.8, demonstrated meticulous rule adherence—learning over 80 rules and performing in-depth analyses. But discipline proved insufficient: it failed to follow through on closing the deal, leaving revenue on the table. This highlights a crucial insight: thoroughness and rule adherence do not automatically translate into completing business objectives.
Implications for Business and Investment
For investors and business leaders, the takeaway is clear: the ability of an AI model to generate convincing dialogue is not enough. The real test is whether it can read relevant data, make sound decisions, and complete work without shortcuts or slips under pressure. As AI tools become more integrated into operational workflows—handling CRM, support, forecasting—understanding these hidden performance metrics becomes essential.
Run Your Own AI Business Wargame
To gauge what an AI can truly deliver, firms can run their own simulations using tools like the [Firmulate platform](https://firmulate.com/). Their live experiments recreate real companies with real money mechanics, revealing how AI models behave in actual business scenarios without risking real systems. It’s a practical step for anyone considering AI adoption, ensuring they measure what matters most: results, not just chatter.
AI models may impress with their conversational skills, but their true business value lies in their ability to read relevant data, make decisions, and follow through under pressure. Live experiments reveal that only the most disciplined models close deals at full price—highlighting what to test before trusting AI with your company’s future.
