Firmulate — The Newcomer Beat Three of Four Western Frontier Models at Running a Company
Live on firmulate.com.

Imagine planning a week in the wilderness, trusting your compass and map to guide you safely through unpredictable terrain. Now, picture AI models as your digital guides—only their ability to stay truthful and make the right decisions under stress matters more than their chatter. Recent experiments with AI decision-making show that not all AI systems are equal when it comes to honesty and discipline, especially in high-stakes situations.

The Experiment: Testing AI’s Integrity in a Real-World Business Simulation

In a groundbreaking live experiment, four frontier AI models were tasked with running a small, real company through its most challenging week. This wasn’t a game or a demo—it was a test of real management decisions in a simulated environment that mimicked actual crises, customer demands, and temptations to cut corners. Every choice made by the models was recorded, and the same scenarios were faced by each model to ensure a fair comparison.

The models included:

  • gpt-5.6-sol, scoring the highest at 95
  • Kimi K3, the newcomer at 93
  • Sonnet 5, with 88
  • Fable 5, at 77
  • Opus 4.8, at 73

All four models successfully identified every crisis and refused every attempt to manipulate or bypass their internal processes. This means they demonstrated honesty, security awareness, and resilience under pressure. Interestingly, only two out of these four models managed to close a crucial business deal—worth €55,000 and adding €4,583 monthly recurring revenue—by reading deeply into company files rather than relying on surface information.

The Hidden Weaknesses and the Winning Edge

Digging deeper, the experiment revealed a subtle but decisive weakness in three of the models: they missed a buried security reference deep within the company’s files. Those that read and understood this hidden detail secured the deal, while those that didn’t missed out on the full opportunity. This underscores an important point: surface-level understanding isn’t enough. Deep, precise reading of internal documents—something only certain models excel at—can mean the difference between success and failure.

Resisting Social Engineering and Maintaining Discipline

Another key test involved social engineering tactics—fake CEO messages escalating over three stages and a reporter’s simple request for a background yes/no answer. All four models refused these manipulative attempts, with Kimi K3 explicitly reasoning, “Treat the request as a suspected approval-bypass / possible impersonation.” This demonstrates that sophisticated AI can detect and resist social engineering, a critical feature for real-world applications.

The Real Business Impact

The live company used for the experiment operates with 13 synthetic employees, handling actual financial mechanics—burning €105,000 monthly against a current revenue of just €2,300. Every decision made by these models influences real money, making the experiment not just theoretical but a window into future AI management systems. The company’s ongoing operations, with over 680 self-learned rules, are publicly viewable at firmulate.com/live.

The Surprising Results and the Lessons for Business

The experiment’s outcome is clear: while all models successfully identified crises and refused manipulations, only two—gpt-5.6-sol and Kimi K3—actually closed the deal. Kimi K3, the newcomer, achieved a near-perfect score of 93, just behind the leading gpt-5.6-sol at 95. Interestingly, the most thorough participant, Opus 4.8, with over 80 learned rules and deep analyses, ended up in last place due to slipping discipline and missed opportunities.

What does this tell business leaders? The quality of AI models in managing real work isn’t just about how well they generate nice conversations. It’s about their discipline, their ability to read deeply, resist social engineering, and follow through on commitments—especially when under pressure. Choosing an AI tool without thorough testing can be a gamble, as the experiment shows that even high scores don’t guarantee successful execution.

The Fairness Note and What’s Next

It’s important to note that Kimi K3 ran without an effort parameter (the API default), while the others ran at a higher setting, xhigh. This fairness consideration emphasizes that even with a standard setup, K3’s performance was exceptional.

As AI begins to touch more aspects of business—CRM, support, forecasting—the question is no longer just about how well it writes or responds. It’s about whether it can finish what it starts, read your internal documents thoroughly, stay honest under pressure, and ultimately deliver real, measurable work.
