DEMO / RECORDING
Overview & Result
Matthew Berman demonstrates a San Francisco scene in Unreal Engine, saying Opus 5.5 recreated the city and Jev powers its people, pets, cars and traffic. The original video shows the city simulation. The integration details and the claim that every entity is Jev-driven remain author-reported.
How Jev fits in the loop
- The author reports using Opus 5.5 to recreate the city in Unreal Engine.
- The video shows the simulated city and its entities.
- The author attributes their behavior to Jev; the source does not expose the decision loop or API implementation.
How to reproduce
- Watch Matthew Berman’s original city video.
- No exact public repository or setup instructions are supplied in this post. A recreation would require separately obtaining the project and integration details.
Why this build matters
Provides a visual example of applying a decision model to simulated entity behavior.
Limitations
- We have not inspected the project code or reproduced the simulation.
- The video alone cannot verify which entities call Jev, call frequency, latency or cost.
