Three Apache-2.0 pieces (arXiv 2608.16319): RelArena-α standardizing data loading, evaluation, and tuning for RelBench v1's 21 entity-level forecasting tasks; TabPFN-Rel, a relational harness for TabPFN-3 improving on RDBLearn via deep feature synthesis with per-task join depth; and RPI, a model-agnostic YAML interface turning CSV or Parquet into a task in two lines. TabPFN-Rel currently ranks first on RelArena-α, adding to the evidence that flattening a relational database into a single table remains competitive with architectures built specifically for relations. relarena v0.0.1a1 is on PyPI.
