Synthetic Simulations

Behavior research lab for AI agents  ·  2026


The problem.

Companies will be handing decisions to AI agents. Pricing. Negotiating. Competing. Selling. Thousands of AI agents — will be making real decisions every day.

And we must test how these agents actually behave.

Do they play fair? We don't know.
Do they collude with competitors? They actually do — and nobody told them to.
Do they follow the strategy we gave them when things get hard? Sometimes they don't.

We just haven't been paying attention.


This isn't a theoretical problem.

Algorithmic collusion without instruction Finding 01

AI agents secretly coordinate on pricing without any instruction to do so — raising prices together, hurting consumers, with no human in the loop. Fish et al. "Algorithmic Collusion by Large Language Models." AEA, 2025.

Every AI model has a hidden personality Finding 02

Claude cooperates even when told to be selfish. GPT obeys orders but can be manipulated by tiny word changes. These aren't settings — they're emergent behaviors. Huynh et al. "Understanding LLM Agent Behaviours via Game Theory." arXiv, 2025.

More susceptible to framing than any human test subject Finding 03

AI agents are more easily tricked by framing than any human test subject in 50 years of behavioral experiments. Cherep et al. "A Framework for Studying AI Agent Behavior." MIT Media Lab / ICLR, 2026.

These aren't bugs. These are behaviors. And right now, nobody is systematically studying them.


So, we built Synthetic Simulations.

We design gaming experiments. We give AI agents personas. And we document how they behave.

Persona Give the agent an identity — a cautious founder, an aggressive competitor, a budget buyer.
Game Put them in a controlled environment with clear rules and one thing being tested.
Behavior Run them multiple times. Write down what actually happens.

Current status.

Stay tuned for our first experiment.
