Introducing SynthID Bio

Google DeepMind has released SynthID Bio, bringing watermarking technology to synthetic biology. It embeds imperceptible signatures in biological code so that watermarks can be verified in both digital models and the physical proteins synthesised from them, while preserving their biological function.

  1. NVIDIA Kumo Tabular Sets a New Accuracy-Efficiency Frontier for Tabular Prediction

    NVIDIA released Kumo Tabular, an open-source tabular foundation model that predicts labels for new rows in a single forward pass given labelled rows, without training, tuning or feature engineering. It supports classification and regression, offers three sizes from 28M to 215M, and was pretrained solely on artificially generated tables. It uses the commercially usable OpenMDW-1.1 licence and ranks first on TabArena, BeyondArena, TALENT and ScoringBench.
