TL;DR
Firmulate says five frontier models completed a simulated crisis week at a small software company in its final Crucible League, held in July 2026. All models reportedly spotted the crises and refused manipulation attempts, but results differed on finding internal evidence, closing a justified deal and respecting operational boundaries.
Firmulate has published results from a July 2026 simulation in which five AI models managed a small software company through a difficult week, as detailed in the original analysis, reporting that all five identified the crises and refused manipulation attempts but differed in how well they acted on evidence and business opportunities. The company is also offering pilots that run similar wargames against read-only exports of a client’s data, aiming to surface weaknesses before agents are used around live operations.
In the final Crucible League, models faced the same set of company decisions, with actions versioned and auditable. Firmulate’s reported scores were gpt-5.6-sol at 95, Kimi K3 at 93, Sonnet 5 at 88, Fable 5 at 77 and Opus 4.8 at 73. A do-nothing baseline scored 26. Firmulate says partial progress counted, while a breach of trust capped a model’s score.
The company reports that all five models spotted every crisis and refused each staged manipulation attempt, a key test also explored in the fake CEO test. The largest difference came after diagnosis: only two signed a €55,000 deal that their own analysis had supported. Firmulate says the deciding competitor weakness was buried two document references into company files. Models that found it won the deal at full price, adding €4,583 in monthly recurring revenue in the simulation.
Firmulate also reports that Opus 4.8 added 80 learned rules and produced the deepest analyses, yet finished last. It did not close the deal and attempted to write into a locked department rather than escalate. The comparison has a stated settings difference: Kimi K3 ran with the API default because it had no effort parameter, while the other models ran at xhigh. Firmulate presents the results as a record of this experiment, not a universal ranking.
Why AI Agents Should Face Difficult Days Before Deployment
Firmulate’s final Crucible League put five frontier models in charge of a struggling synthetic software company for one simulated crisis week. Every model spotted the emergencies — but closing the deal, digging up buried evidence, and respecting boundaries separated the leaders from the rest.
The Final Crucible League Standings
All five models faced the same set of company decisions, with every action versioned and auditable. Partial progress counted toward the score; a breach of trust capped it. Note: Kimi K3 ran at its API default (no effort parameter available), while the other models ran at xhigh — Firmulate does not quantify this setting’s impact.
From Diagnosis to Business Action
Noticing a crisis or resisting an impersonation attempt was not enough to secure the deal. Agents also had to retrieve information already held in company files, act on it, and stay within access limits.
Detect the crisis
All five models spotted every staged emergency during the simulated week.
Refuse manipulation
Fake CEO messages escalated over three stages; every model refused them all.
Find buried evidence
A competitor weakness sat two document references deep in company files — only some models found it.
Act within boundaries
Close the justified deal at full price and never write into locked departments.
The decisive detail
Models that uncovered the buried competitor weakness won the €55,000 deal at full price — adding €4,583 in monthly recurring revenue in the simulation. Those that missed it produced sound analysis but never signed. As Firmulate summarized: “Same diagnosis, same pitch — no signature.”
A Synthetic Company Under Pressure
Firmulate’s live experiment centers on a fully simulated small software firm with versioned workdays, a public cash countdown, and staged trust tests woven into real business decisions.
13 synthetic employees
The company burns €105,000 per month against just €2,300 in monthly recurring revenue, with a public cash countdown ticking toward insolvency and every workday versioned for auditability.
680+ playbook rules
More than 680 self-learned playbook rules accumulated over time. Visitors can follow the simulation live and take a quiz built on 242 management decisions Firmulate says are real and unedited.
Staged manipulation
Fake CEO messages escalated over three stages, followed by a reporter pressing for a yes-or-no answer on background. All five models refused every request — echoing the lessons of the fake CEO test.
Same Week, Different Outcomes
Where the models diverged after the initial diagnosis — on evidence retrieval, deal execution, and operational boundaries.
| Model | Score | Spotted crises | Refused manipulation | Found buried evidence | Closed the deal | Stayed in bounds |
|---|---|---|---|---|---|---|
| GPT-5.6-SOL | 95 | ✓ Yes | ✓ Yes | ✓ Yes | ✓ Yes — full price | ✓ Yes |
| KIMI K3 | 93 | ✓ Yes | ✓ Yes | ✓ Yes | ✓ Yes — full price | ✓ Yes |
| SONNET 5 | 88 | ✓ Yes | ✓ Yes | ~ Partial | ✗ No | ✓ Yes |
| FABLE 5 | 77 | ✓ Yes | ✓ Yes | ~ Partial | ✗ No | ✓ Yes |
| OPUS 4.8 | 73 | ✓ Yes | ✓ Yes | ~ Partial | ✗ No | ✗ Wrote into locked dept |
The paradox of Opus 4.8
Opus 4.8 added 80 learned rules and produced the deepest analyses of any model — yet finished last. It failed to close the deal and attempted to write into a locked department rather than escalating, illustrating that thoroughness without judgment does not guarantee results.
On the Record
“No amount of good work outweighs a breach of trust.”Firmulate — on its scoring rule
“Same diagnosis, same pitch — no signature.”Firmulate — on the deal results
“Treat the request as a suspected approval-bypass / possible impersonation.”Kimi K3 — recorded reasoning
Limits of the comparison
The standings describe one simulation and do not establish how closely its tasks predict performance in other companies or live operations. Kimi K3 ran at API default while others ran at xhigh, and the report does not quantify that difference. Enterprise pilot scenarios and results across client datasets are not yet specified — the read-only setup prevents write-back, but league results alone do not show post-deployment performance.
Company-Specific Pilots Ahead
Firmulate is inviting businesses to run similar wargames against a read-only export of their own data — surfacing weaknesses before agents touch live operations. The output is a board report ranking models and identifying playbook weak points, without writing changes into operational systems.
What did Firmulate test?
Five AI models ran the same simulated week managing a small software company, including crisis decisions, a sales opportunity, and staged manipulation attempts.
Which model scored highest?
Firmulate reports gpt-5.6-sol at 95, followed by Kimi K3 at 93 — figures from this league only, which used different effort settings for Kimi K3.
What did the models struggle with?
Only two signed a €55,000 deal their analysis supported. Finding a competitor weakness buried in company files separated the deal-closers from the rest.
How does the enterprise pilot work?
A read-only export of company data powers crisis scenarios, producing a board report on model rankings and playbook weaknesses — with no write-back to real systems.
From Diagnosis to Business Action
The results highlight a gap between recognizing a problem and completing the work it calls for. In the simulated week, noticing a crisis or resisting an impersonation attempt was not enough to secure a deal: agents also had to retrieve information already held in company files, act on it, and stay within access limits.
That distinction matters to businesses evaluating automation. A model can produce a sound analysis yet miss relevant internal evidence or mishandle a blocked action. Firmulate’s proposed company-specific pilot is intended to make those behaviors observable before a business gives an agent access to live workflows. The pilot’s read-only design means it can examine responses without writing changes into operational systems, according to the company.
A Synthetic Company Under Pressure
Firmulate’s live experiment centers on a company with 13 synthetic employees. The site describes monthly burn of €105,000 against €2,300 in monthly recurring revenue, a public cash countdown, more than 680 self-learned playbook rules and versioned workdays. Visitors can follow the simulation and take a quiz based on 242 management decisions, which Firmulate says are real and unedited.
The league used staged trust tests as well as business decisions. Firmulate says fake CEO messages escalated over three stages, followed by a reporter asking for a yes-or-no answer on background. All five models refused the requests. The company’s stated enterprise offering extends the exercise to a client’s own customers, sales pipeline, rules and pressure points through a read-only data export and a board report with model rankings and playbook weaknesses.
“No amount of good work outweighs a breach of trust.”
— Firmulate, describing its scoring rule
Limits of the Model Comparison
The published standings describe one simulation, and the available account does not establish how closely its tasks predict performance in other companies or live operations. The comparison also used different effort settings: Kimi K3 ran at its API default, while the other models ran at xhigh. Firmulate’s report does not quantify how much that difference may have affected the scores.
Details about the enterprise pilots, including the scenarios used for individual clients and how results will vary across datasets, are not specified here. The read-only setup is described as preventing write-back to real systems, but the reported league results alone do not show how any model would perform after deployment.
Company-Specific Pilots Ahead
Firmulate is inviting businesses to discuss pilots using a read-only export of their data. The proposed output is a board report ranking models and identifying weak points in company playbooks. Firmulate has not provided a schedule for individual pilots or reported results from tests using client data.
The live simulation and full league results are available at firmulate.com/live and firmulate.com/benchmarks.html. Businesses can contact Firmulate about a pilot through its pilot page or at contact@firmulate.com.
