BrickBench is a new benchmark for evaluating agentic, text‑conditioned LEGO‑set design. In each task, an agent receives a prompt and must produce a physically buildable assembly that meets semantic and design criteria by selecting parts from a discrete library while reasoning about local and global constraints. The benchmark scores designs on validity, alignment, and design across three settings that vary in scale and part availability, and it includes BrickAgent, an environment for coding, inspecting, and validating agent outputs.

Computer-use agents are increasingly evaluated in realistic desktop environments, but existing benchmarks provide limited coverage of professional engineering workflows whose outputs are persistent, s...
Procedura is a new 3D modeling agent that treats 3D shape as code, using a large language model to generate a procedural assembly from a text prompt. It constructs an assembly graph, writes a parametric program with named parts and typed mates, and verifies each part through compile, mate, and connectivity checks before adding it. A vision critic refines the assembly step‑by‑step, and the resulting program includes per‑part materials and simulator‑validated articulation, producing sharp edges and editable, part‑structured outputs that outperform existing native 3D generators on P3D‑Bench and MechBench‑36.
