## Summary

Ai2 introduces ToyBlocks, an open simulation framework with a robot arm and blocks for studying robot learning and evaluation. It automatically generates tasks and demonstrations, and it reports 85,336 long-horizon demonstrations across nearly 1,600 hours of execution data and 144 million frames. The post also reports tests of VLA spatial generalization, high-level planning, and world models, with a real-robot comparison showing 50.0% success on 30 episodes versus 55.5% in simulation.
