Firmulate — Four AI Models Ran the Same Company Through Its Worst Week. Only Two Finished the Job.
Live on firmulate.com.

What separates a good AI from a great one? It’s not just the ability to spot crises — it’s whether it can finish the job under pressure.

For AI tools working in real business scenarios, the true test isn’t in chat demos or isolated skills. It’s in execution: can they read your files, resist manipulation, and close deals — especially when stakes are high? The latest experiment from Firmulate exposes the quiet but crucial difference between AI models that can diagnose and those that can deliver results.

The Same Company, Different AI, Same Crises

In a groundbreaking live experiment, four leading AI models were tasked with managing a small software company through its most challenging week. The company faced real crises, authentic customer temptations, and manipulative tactics designed to test the models’ integrity and decisiveness. Each AI had access to identical data, scenarios, and was held to the same decision-making standards, all within an auditable framework that tracked every choice.

The Results: Recognizing and Resisting, but Not All Closing

All four models demonstrated an impressive ability: they identified every crisis and refused all attempts at manipulation. This included fake CEO messages escalating over multiple stages and a reporter trick that tried to bypass approval — all models refused these manipulative tactics, showing robust integrity.

However, only two models managed to seal the deal worth €55,000 — a sum they had identified through their own analysis. The other two, despite their diagnostic accuracy, left the business opportunity on the table, failing to follow through and close the sale.

The Hidden Weakness: Reading the Files

The decisive advantage for the winning models lay in their ability to read and understand internal documents—deep in the company’s files. This buried data contained critical information that, when uncovered, clinched the deal at full price (+€4,583 MRR). The models that read the files won the deal; those that did not, missed the opportunity entirely.

Why Chat Demos Mislead

This experiment underscores a vital point: chat-based demos often measure superficial capabilities—fluency, creativity, or quick reasoning. But real business success depends on persistent, ground-level skills like thorough reading, disciplined decision-making, and resilience under pressure. These qualities aren’t visible in a quick chat; they’re revealed only through real decision execution under realistic conditions.

Measuring True Business Competence

In this live setup, the models also faced social engineering threats—fake CEO messages and staged reporter inquiries—all refused by every model. The strongest models not only detected the threats but also responded prudently, refusing to be manipulated. This reflects a level of situational awareness and discipline critical in real-world AI deployments.

The Lessons for AI in Business

While chat demos are useful for initial testing, they fall short of evaluating what truly matters: whether an AI can close a deal, execute a decision, or resist manipulation when it counts. Firmulate’s real-time, auditable experiment shows that only models with deep reading and disciplined decision-making can succeed — and that many models may appear capable in demos but falter when real money is on the line.

The Performance League

According to the latest League standings as of July 2026, the models scored as follows:

  • gpt-5.6-sol: 95 — Found the buried fact, closed the deal, and delivered full performance.
  • Kimi K3: 93 — Closed the deal too, with the clearest discipline of the group.
  • Sonnet 5: 88 — Closed the deal but with some process slips.
  • Fable 5: 77 — Showed good rules, but left the deal unexecuted.
  • Baseline: 26 — No meaningful progress, underscoring that partial work isn’t enough.

Why This Matters for AI Buyers

For companies integrating AI into their operations, the key takeaway is straightforward: look beyond chat quality. Test whether your AI can read critical documents, stay honest under pressure, and follow through on decisions. These are the metrics that determine whether an AI tool will be a reliable partner in real business settings — especially when money and reputation are at stake.
