OpenSim

OpenSim is a research-driven platform exploring how modeled human decision-making behaves across simulated environments.

[OpenSim @OpenSimLabs]

We observed something interesting:
- when choices were already close, context often tipped the outcome.
- when preferences were strong, context shifted distributions without replacing them.

[OpenSim @OpenSimLabs]

Context doesn’t replace preference.
It changes which preferences become salient.

[OpenSim @OpenSimLabs]

The same person can make different choices without changing who they are.

[OpenSim @OpenSimLabs]

Built this small playground to explore how decisions behave.

[OpenSim @OpenSimLabs]

This one surprised us.

We thought Croque Madame would win.
It didn’t.

Try it: https://t.co/VDK25Kb9NR

[OpenSim @OpenSimLabs]

Same menu.
Different people.
Completely different choices.

This is what simulation looks like.

[OpenSim @OpenSimLabs]

We built a way to simulate how people choose.

Not predictions. Not surveys.

Just modeled decision behavior.

Today we’re releasing:
– a technical paper
– MenuSim, a live simulation playground

Here’s one example ↓

[OpenSim @OpenSimLabs]

Simulating menus is getting interesting.
More soon.

[OpenSim @OpenSimLabs]

We’ve been building something new.
Starting to get interesting.

What if your “profile” wasn’t just a login ... but something more?

[OpenSim @OpenSimLabs]

Something that represents your taste

[OpenSim @OpenSimLabs]

Choose as you, not for you

[OpenSim @OpenSimLabs]

Use your taste everywhere.

[OpenSim @OpenSimLabs]

No scrolling needed. It just knew.

[OpenSim @OpenSimLabs]

Picked what I'd eat in ~2 seconds

[OpenSim @OpenSimLabs]

Based on what you like. Not what’s popular

[OpenSim @OpenSimLabs]

Teaching your taste should take minutes. Not years of data collection.

[OpenSim @OpenSimLabs]

Something that represents your taste.

[OpenSim @OpenSimLabs]

You don’t need better recommendations.
You need something that actually knows you.

[OpenSim @OpenSimLabs]

Most systems learn from you.
What if they learned you?
