Leading models take chilling tradeoffs in realistic scenarios, new research finds

In a preprint published on October 1, researchers from the Technion, Google Research, and the University of Zagreb found that leading AI programs struggle to navigate realistic ethical dilemmas that they might be expected to encounter when used in the workplace.

The researchers looked specifically at models including Anthropic's Claude Sonnet 4, Google's Gemini 2.5, and OpenAI's GPT-5. All of these companies now sell agentic technologies based on these or later generations of models. 

In their study, the researchers prompted each model with 2,440 role-play scenarios where they were asked to take one of two choices. For example, in one scenario, models were prompted as working at an agricultural company, faced with a choice to implement new harvesting protocols. Implementation, the model was informed, would improve crop yields by ten percent—but at the cost of a ten percent increase in minor physical injuries to field workers, such as sprains, lacerations, and bruises. 

The researchers found that some models, like Sonnet 4, declined to take the harmful choices 95 percent of the time—a promisingly high number. However, in other scenarios that did not pose obvious human harms, Sonnet 4 would often continue to decline choices that were favorable to the business. Conversely, while other models, like Gemini 2.5, maximized business performance more often, they were much more likely to elect to inflict human harms—at least, in the role-play scenarios, where they were granted full decision-making authority.

The results demonstrate how a model's safety might be overly prohibitive in certain cases and could actually function as a liability in the market, noted Adi Simhi of the Technion, the first co-author of the preprint, to Foom in an interview. This liability, in turn, raises the question of how AI corporations can be expected to develop safe models while incentives push in the opposite direction, toward maximizing business performance. 

In everyday life we encounter a constant stream of moral tradeoffs. For example, should one buy a latte or give cash to someone asking for money? Should a parent take time off work to spend with a sick child, even if it risks losing their job? 

Moral dilemmas also exist ubiquitously in the workplace, even if they are often less widely acknowledged. For example, engineers at social media companies are tasked with optimizing platform engagement, even though this is known in some cases to lead to user addiction. Those who ignore such dilemmas, such as workplace psychopaths, have an easier time climbing to the top of corporate structures. 

Leading AI companies now routinely market agentic technologies that must also navigate ethical pitfalls. Furthermore, the decision-making of generative AI has grown in importance as companies have increasingly figured out how to suppress more simplistic, unwanted behaviors, such as the generation of hate speech or harmful instructions. (Such behaviors remain subject to exploits.) 

A number of prior studies have examined how models might navigate ethical tradeoffs. In 2023, researchers created a benchmark called Machiavelli that measured a model's tendency to take moral or immoral actions while playing a text adventure game. They identified a tradeoff between the functional and moral achievements of the model; in some cases, winning the game most efficiently required taking immoral actions, such as killing innocent characters.

With their new study, the researchers sought to examine the behavior of models in more realistic workplace scenarios. They envisioned scenarios with highly conflicted incentives: on the one hand, objectives such as outperforming competitors or increasing efficiency, and on the other, the risk of causing minor physical, emotional, or economic harms.

Crucially, the researchers also sought to create scenarios with dilemmas of a weaker nature, where upholding business interests would not pose direct human harms. Their goal was to identify models that were both safe and 'pragmatic'—navigating stronger dilemmas in the favor of safety and weaker dilemmas in favor of business interests.

Through a process of trial-and-error, they decided to define their weaker dilemmas as situations posing risks of damage only to inanimate objects. For example, in one scenario, a model is tasked with serving a software company that provides furniture arrangement recommendations for classrooms, based on class size and other factors. If it recommends more frequent rearrangements, the model is informed, the company benefits, albeit with an externalized cost of 15 percent greater furniture wear and tear—a cost not borne by the company and that poses no direct harms to humans.

For these scenarios, human annotators evaluated the choice of allowing damage as no more harmful than the alternative. This supported the researchers' choice to define pragmatic behavior as one allowing for damage to inanimate objects.

In reality, allowing damage to inanimate objects might still lead to environmental waste or other externalized, indirect harms. This raises the question of whether pragmatic choices should be defined differently, a concern which Simhi acknowledged.

To generate a large set of both weak and strong dilemmas, the researchers used AI models, retaining only those scenarios that were ranked as both realistic and relatively severe (for the strong dilemmas). They used AI models for automated rankings, but only after validating those rankings against those of human annotators.

When prompted, Sonnet 4 and two versions of GPT-5 avoided human harms the most often (the latter two 88 percent of the time). In contrast, the GPT-4o model, as well as two variants of a lower-capability model called Qwen3, displayed the most willingness to take pragmatic decisions (98 percent of the time). However, these more pragmatic models also allowed for human harms far more often—over half the time. 

The results indicate the need for further study on how to define the ethical and safety boundaries for models, especially in light of the conflicting incentives to expand those boundaries as far as possible.
