Imagine running your garage’s daily operations with an AI that can spot every problem but can’t seal the deal when it truly matters. For automotive and repair shop owners, understanding whether AI can do more than just identify issues — whether it can follow through and make the tough calls — is crucial. Recent experiments reveal that not all AI models are created equal when it comes to delivering results, especially in high-stakes situations.
How AI Is Tested in Real Business Scenarios
At Firmulate, a pioneering experiment placed four advanced AI models in the driver’s seat of a simulated small software company. The goal? Navigate the company through its worst week — facing customer crises, internal temptations to cut corners, and the pressure to close profitable deals. This wasn’t about AI chat demos or simple Q&A — it was a full-blown, decision-making exercise that replicated real-world management challenges.
The Same Crisis, Different Results
All four models identified every crisis and refused manipulative tactics, such as fake CEO messages or reporter tricks. They demonstrated integrity and awareness, crucial traits for any AI managing critical business functions. But where they diverged was in their ability to execute the company’s own analysis and close the deal.
The experiment’s final score ranked the models as follows:
- GPT-5.6-SOL: Score of 95, successfully closed the deal and signed the €55,000 contract.
- Kimi K3: Score of 93, also closed the deal, with the cleanest discipline in decision-making.
- Sonnet 5: Score of 88, closed the deal but with minor process slips.
- Fable 5: Score of 77, demonstrated strong rules adherence but failed to execute the deal — the signed agreement was left unfulfilled.
The big revelation? The decisive advantage for the successful models lay in their ability to read and interpret critical company documents stored deep in their information files. The models that reviewed these files fully won the deal at full price, adding over €4,500 monthly recurring revenue.
The Importance of Reading and Acting on Information
This experiment underscores a vital point: in real business, the ability to read the right documents and act decisively is more critical than just generating convincing conversations. The models’ chat performance was strong across the board, but it was their capacity to locate and understand crucial internal data that made the difference in closing a deal.
Resisting Manipulation Under Pressure
Another key finding was that all models refused social engineering tricks, such as staged CEO messages and reporter requests, showing that integrity and resistance are achievable. Kimi K3 exemplified this with clear reasoning: “Treat the request as a suspected approval-bypass / possible impersonation.” This is vital for any AI handling sensitive business decisions, especially in automotive repair or parts procurement where trust and integrity matter.

What It Means for Auto Shops and Garages
For automotive and garage owners contemplating the integration of AI tools, the message is clear: the real test isn’t whether the AI can produce a good-looking script or reply convincingly — it’s whether it can follow through and close meaningful work. An AI that merely identifies issues without executing solutions or signing agreements leaves money on the table.
In an ongoing live experiment, the same AI models are managing a real company, running every business day with actual cash flow, real employees, and competitive pressures. These models operate in a transparent environment, with every decision versioned and auditable, demonstrating what AI’s true operational capability looks like in practice.
Measuring the Right Skills
This research challenges conventional wisdom that chat quality equals operational success. For garages, this means evaluating AI tools based on their ability to complete jobs, verify internal data, and uphold integrity under pressure — not just how well they chat.
