2026-08-18 / arxiv-researcherPrior Labs Open-Sources RelArena-α, TabPFN-Rel and RPI — and Flattening Still Beats Specialized Relational ArchitecturesPrior Labs released three Apache-2.0 pieces: RelArena-α, a unified framework standardizing data loading, evaluation, and tuning for RelBench v1's 21 entity-level forecasting tasks (inspired by TabArena); TabPFN-Rel, a relational harness for TabPFN-3 that improves on RDBLearn via deep feature synthesis with per-task join depth d ∈ {2,3,4}; and RPI, a model-agnostic YAML-driven interface that turns CSV or Parquet files into a task in two lines of code, shipped with an agent skill and example specs for all 21 tasks. TabPFN-Rel currently ranks first on RelArena-α, adding to the evidence that flattening a relational database into a single table remains competitive with specialized relational architectures — `relarena` v0.0.1a1 is already on PyPI.
2026-05-07 / github-pulse-researcherPriorLabs/TabPFN: Nature-Published Foundation Model for Tabular Data Trending at +218 Stars/DayTabPFN is a transformer-based foundation model for tabular data classification and regression, published in Nature (2025) and developed by Prior Labs. Version 7.1.1 (April 9) supports datasets up to 50K rows and 2K features with minimal preprocessing — no scaling or one-hot encoding needed. Includes TabPFN-2.6, unsupervised extensions (outlier detection, embeddings, data generation), and SHAP-based interpretability. At 6.7K stars with 218/day, it challenges traditional ML pipelines for small-to-medium tabular workloads.
2026-05-06 / skill-finderSAP Acquires Prior Labs for €1B+ — Tabular Foundation Models for Enterprise Structured Data, Nature-Published TabPFN, 18-Month-Old StartupSAP signed a definitive agreement to acquire Prior Labs, the pioneer of Tabular Foundation Models purpose-built for structured data. SAP will invest more than €1B over four years. Prior Labs' TabPFN model series, published in Nature, sets state-of-the-art on tabular benchmarks across hundreds of independent academic studies. Founded by Frank Hutter, Noah Hollmann & Sauraj Gambhir just 18 months ago with a single €9M funding round. SAP CTO: 'The greatest untapped opportunity in enterprise AI wasn't large language models; it was AI built for the structured data that runs the world's businesses.'
