BrickBench: Evaluating Agentic Brick Design

We propose BrickBench, a benchmark for agentic text-conditioned LEGO-set design.

Key points

  • Given a prompt, an agent is tasked with producing an assembly that not only satisfies semantic and design criteria, but that can also be physically built.
  • To do so, it must select parts from a discrete library and reason jointly about local and global constraints.
  • We provide BrickAgent, an environment for coding agents to construct, inspect, and validate their designs.
  • We find that leading agents largely satisfy verifiable physical and semantic requirements, but fall short of human designs.
