A new study published on arXiv highlights a significant issue with astronomical foundation models, specifically AION-1. Researchers found that the model's reliance on survey detection channels, rather than the actual pixel data, leads to substantial biases in its predictions for quantities like flux, size, and redshift. This reliance on metadata, even when inaccurate or incomplete, overrides the visual information, causing errors that exceed requirements for astronomical surveys like LSST DESC. The study suggests that removing the detection channel metadata significantly improves model performance without measurable cost. AI
