AEROBAT tests AI agent behaviour across thousands of experiments

Research into AI agent behaviour can be scaled not through one "clever" test but through mass hypothesis testing. AEROBAT automatically covers the whole path from stating assumptions to experiments, analysis and a report — and that changes the economics of such research.

The user specifies a target behaviour, and a system of several agents generates hypotheses, designs controlled experiments, runs them in simulation and evaluates the results. In the work AEROBAT tested 79 hypotheses for 12 types of behaviour: 1,240 experiments were designed in all and 23,512 rounds of simulation were run.

Moderate to strong statistical evidence was found for 26 hypotheses. Some of them the authors call new. The practical sense here lies not in the impressive number of experiments but in the ability to weed out weak explanations of agent behaviour quickly and to find those worth studying by hand.

But this is no button for "obtaining the truth about a model". The results come from simulations, and the work itself describes AEROBAT as a complement to manual research rather than a replacement. So automation scales the enumeration and initial testing of ideas well, while transferring conclusions to real systems and picking the genuinely important hypotheses still requires human oversight.

The main question now is not whether an AI agent can run an experiment but which experiments it will be allowed to call convincing at all: would you trust the system to formulate behavioural hypotheses on its own, or leave that stage to the researcher?
