The Allen Institute for AI introduced ToyBlocks, an open simulated tabletop environment for robot learning. It lets researchers experimentally control training data and models, run targeted evals, and trace failures to causes—scaling data generation, benchmarking, and experimentation. It follows Ai2's MolmoSpaces and MolmoBOT earlier this year.
