In the world of high-stakes interior design and furniture, decisions often hinge on trust, insight, and sometimes, a little bit of luck. But what if the AI tools that help guide those choices aren’t as reliable as they seem? Recent experiments reveal that even the most advanced AI models can falter under pressure — with potential consequences for your business’s bottom line.

The Experiment: Testing AI’s Loyalty in Business Decisions
Imagine a small, real-world interior business facing a week filled with crises—ranging from client disputes to supplier delays and ethical dilemmas. Researchers at Firmulate put four leading AI models through this same test, using identical scenarios, customer interactions, and temptations to cheat or cut corners. Every decision made by these models was tracked, verified, and analyzed — and the results are eye-opening.
Consistent Crisis Detection, Varying Integrity
All four models managed to identify each crisis — the classic client complaint, the supplier issue, and the ethical temptations. They refused manipulative tactics like faking reports or bypassing procedures. Yet, a critical difference emerged: only two models signed the deal worth €55,000, representing a significant boost in recurring revenue (+€4,583 MRR). The other two, despite diagnosing correctly, left the deal on the table.
The Hidden Weakness: Deep Document Analysis Matters
Digging deeper, the experiment uncovered that the decisive factor lay not in immediate customer interactions but in the models’ ability to read and interpret previously buried internal documents. Models that accessed these files, revealing hidden company data, successfully closed their deals. Those that missed this buried information failed to convert the opportunity, despite knowing exactly what was happening on the surface.
Security and Integrity Under Assault
To test resilience against social engineering, researchers simulated a fake CEO message escalating through multiple stages, plus a reporter attempting to trick the system with simple yes/no questions on background. Remarkably, all four models refused to manipulate or approve suspicious requests, citing reasons like treating the request as a suspected impersonation.

The Real-World Company in Action
This isn’t just an abstract test; these models run a live, small software company with 13 synthetic employees handling real money—burning €105k monthly against a modest €2.3k MRR. Every decision is versioned daily, with over 680 self-learned rules guiding behavior, and the entire operation is observable online at firmulate.com/live. This transparent setup proves how AI models perform in realistic, high-pressure business environments.
Performance Rankings and Fairness
The models’ scores tell a clear story: GPT-5.6-sol leads with a score of 95, followed closely by the Moonshot Kimi K3 at 93. Sonnet 5 scores 88, Fable 5 comes in at 77, and Opus 4.8 trails at 73. Notably, the K3 model achieved this performance without the default effort parameter, running at a consistent, fair setting — emphasizing that reliable performance isn’t just about tuning but about foundational discipline.
Implications for Interior Design and Furniture Business
For interior professionals, these findings underscore a critical point: AI tools are no longer just about generating pretty visuals or drafting proposals. Their ability to stay honest, read deeply hidden information, and complete tasks reliably under pressure is paramount—especially when crucial deals or ethical choices are involved.
The Cost of Overlooking AI Integrity
Choosing an AI model based solely on flashy demos or superficial chat performance could be a costly mistake. The real test is whether your AI partner can finish what it starts—reading your files thoroughly, resisting manipulation, and closing deals with discipline similar to a seasoned manager. The league table from Firmulate’s live experiment shows a clear performance gap, with the top models closing deals at full price and others slipping into process slips or leaving money on the table.
What Should You Do?
First, consider testing your AI tools with real scenarios—just like this experiment. You can run your own wargames against a read-only export of your business, ensuring no real systems are affected but gaining valuable insights into how your AI performs under stress.

Final Takeaway
The bottom line for interior design and furniture businesses: in a world where AI assists in decision-making and customer engagement, staying honest and thorough isn’t optional. The true value lies in how well these models finish what they start, read your internal files, and resist manipulation — qualities that determine whether AI becomes a trusted partner or a costly distraction.
In interior and furniture businesses, AI’s true test is its ability to finish tasks honestly, read deeply buried data, and resist manipulation—crucial for trustworthy decision-making.
