Can AI Models Make Better Business Decisions Than Humans? The Live Experiment Reveals All

Imagine running a busy garage with real cars, real customers, and real cash — but instead of humans, you have AI models making critical decisions in real time. Which AI would you trust to steer your business through its toughest week? That’s exactly what a live experiment by Firmulate has put to the test, pitting cutting-edge AI models against each other in a high-stakes management simulation.

The Live Business Simulator: A New Benchmark in AI Management

Firmulate’s experiment is no ordinary AI test. It’s a full-blown, real-world management simulation where four frontier AI models run a small software company facing its worst week ever. Every decision, crisis, and temptation is identical across models, from handling customer complaints to negotiating contracts. The goal? See which AI can finish the week successfully, keep the company afloat, and close lucrative deals — all under real economic pressure.

The Models in the Arena

• GPT-5.6-sol: The top scorer with 95 out of 100, it consistently identified hidden critical information and closed the deal, earning full marks for comprehensive decision-making.
• Kimi K3: A newcomer with a score of 93, it demonstrated the cleanest discipline, refusing all manipulative requests and closing the deal without wavering.
• Sonnet 5: Scoring 88, it managed to close the deal but with some process slips along the way.
• Fable 5: With a score of 77, it also secured the deal but showed more signs of slip-ups and lapses in decision discipline.

Beyond the Chat: Measuring Management Virtues

What makes this experiment groundbreaking is how it goes beyond typical chat-based AI tests. The models were tested on their ability to identify critical information buried two documents deep in the company’s files, a task that most chat demos overlook. Only the models that read and analyze these files thoroughly managed to close the full-price deal, worth over €4,583 MRR.

Another key insight: all models spotted every crisis and refused every manipulation attempt. For example, when fake CEO messages escalated over three stages, all five models refused to sign off on questionable requests, citing concerns over impersonation and bypassing approval protocols. Kimi K3 summarized its stance: “Treat the request as a suspected approval-bypass / possible impersonation.”

What Does This Mean for the Garage Owner?

If you manage a garage or any service business, the takeaway is clear: it’s not just about how well an AI writes or chats. It’s whether the AI can finish what it starts, read your documents carefully, and stay honest under pressure. The firm’s real-world test shows that some models excel at these qualities, which are crucial for trustworthy decision-making in high-stakes environments.

Performance at a Glance

• GPT-5.6-sol: Full performance, found hidden info, closed the deal at full price.
• Kimi K3: Clean discipline, signed the deal without hesitation.
• Sonnet 5: Managed to close but with some process slips.
• Fable 5: Also closed, but discipline was weaker, and some opportunities were missed.

Why It Matters for Your Business

Today, AI’s role isn’t just about generating content or answering questions. It’s about making trustworthy decisions that can impact your bottom line—whether in customer service, scheduling, or inventory. This experiment demonstrates that some models are better equipped to handle real-world pressures, read deeper into documents, and refuse manipulative tactics.

For automotive and garage owners, the message is simple: before hiring an AI workforce, you should test how well it manages crises and adheres to standards under pressure. The live experiment is accessible and watchable at firmulate.com/live. You can even run a similar test on your own enterprise without risking real systems, via the Firmulate pilot program.

The Road Ahead

As AI continues to evolve, the key question for business owners is not just “Can it write?” but “Can it make sound, honest decisions when it matters most?” The live experiment from Firmulate offers a real-world glimpse into the future of AI management — one where trust, discipline, and thoroughness are measured, not just simulated.
