Glioblastoma recurrence is largely driven by diffuse infiltration beyond radiologically visible margins, yet current radiotherapy guidelines rely on uniform margin expansions that ignore patient-specific biology and anatomy. While computational models promise to map this invisible growth and guide personalized planning, their clinical translation is hindered by a lack of standardized benchmarking and reproducible validation. To bridge this gap, we present PREDICT-GBM, an open-source platform integrating a curated, longitudinal, multi-center dataset of 243 patients with a standardized evaluation pipeline. We benchmark a novel U-Net-based recurrence prediction model against state-of-the-art biophysical and data-driven methods. Under iso-volumetric constraints, both biophysical and deep-learning approaches achieved modest but statistically significant gains in geometric coverage of future recurrence over guideline-based plans. On the combined cohort, our U-Net achieved the highest mean coverage of enhancing recurrence (79.37 ± 2.08%), surpassing guideline-based plans (paired Wilcoxon signed-rank test, Benjamini-Hochberg adjusted p = 2.9 × 10-5). The biophysical model GliODIL reached 78.91 ± 2.08% (p = 1.0 × 10-3), validating the platform's ability to compare diverse modeling paradigms. By providing a reproducible ecosystem for model training and validation, PREDICT-GBM addresses a major bottleneck toward personalized, computationally guided radiotherapy. The platform, models, and data are openly available at github.com/BrainLesion/PredictGBM .
