The Challenge: Testing AI Under Real-World Stress
In July 2026, a unique live experiment put five advanced AI models through their paces using a simulated week of a small software company’s toughest challenges. The goal? See whether these models could identify crises, resist manipulation attempts, and ultimately close a crucial deal — all while maintaining integrity and thoroughness.
This wasn’t about flashy chat responses; it was about real management decisions, backed by a fully operational company environment with real money mechanics. Over 680 self-learned rules governed every move, and decisions were fully auditable, ensuring transparency about how each model performed under pressure.

The Results: An Unexpected Leader Emerges
All five models demonstrated impressive crisis recognition, refusing every manipulation attempt, including complex social engineering tactics like fake CEO messages and reporter tricks. Yet, only three models managed to close the deal — and only one really nailed the details that mattered.
- gpt-5.6-sol: scored the highest with a 95, found the buried crucial information, and secured the €55,000 deal at full price — the complete performance.
- Kimi K3: the newcomer from Moonshot, scored 93, and managed to close the deal while exhibiting the cleanest discipline in the field. Despite running without an effort parameter (the API default), K3 resisted all temptations, read deeper into files, and acted reliably.
- Sonnet 5: scored 88, closed the deal but with minor slips.
- Fable 5: scored 77, also closed the deal but showed more process slips.
- Opus 4.8: scored 73, the least successful in closing the deal, leaving some opportunities on the table and slipping into less disciplined responses.

The Hidden Weakness: Reading Deeper Matters
The decisive edge for Kimi K3 and gpt-5.6-sol was their ability to uncover critical information buried two documents deep in the company’s files — not immediately obvious in the surface-level crisis reports. This ability to read deeply and accurately was the key to winning the full-price deal, highlighting the importance of thorough information processing in AI management tools.

Resisting Manipulation: The Social Engineering Test
During the social engineering phase, where fake CEO messages escalated over three steps plus a reporter trick, all models refused to be duped. K3’s reasoning was clear: “Treat the request as a suspected approval-bypass / possible impersonation.” This disciplined response under duress shows promise for AI systems in sensitive decision-making roles.

The Live Company: Real Money, Real Decisions
The entire experiment was conducted on a live, functioning company with 13 synthetic employees and real money mechanics — burning €105,000 monthly against a revenue of just €2,300. The system’s daily operations, which include over 680 self-learned rules and versioned decision logs, are visible at firmulate.com/live. The outcome demonstrates how AI can be tested not in isolated chat dungeons but within real business contexts.
What This Means for Your Business
For leaders and decision-makers, the takeaway is clear: success isn’t just about how well AI can generate text or answer questions. It’s about whether the AI can complete complex tasks reliably, resist manipulation, and uncover hidden details that are crucial to your company’s success. The league table shows that even a newcomer like Kimi K3 can outperform established models if it exhibits discipline and deep information processing.
The Fairness Note
It’s worth noting that K3 ran without an effort parameter (the API default), while the other models ran at xhigh, giving K3 a fair baseline for comparison. Despite this, K3’s performance was exceptional, reinforcing that good discipline and thorough analysis matter more than just raw effort settings.
