Towards Easier-to-Tune Training Algorithms: New Results from AlgoPerf

Evaluating deep learning optimizer is challenging because confounding factors such as hyperparameter tuning and optimizer-model co-design often obscure true algorithmic performance. We present results of the updated AlgoPerf V1 benchmark, in which we evaluate a new set of training algorithms on wall-clock time-to-targe...

How Good Are Frontier Models at Physics? Expert Re-Grading Reveals Broken Evaluations and Near-Saturation of Leading Benchmarks

Evaluating frontier models on six widely used physics benchmarks and auditing them with experts suggests that current benchmarks substantially understate frontier models'ability to solve well-posed physics problems.

Semigroup-JEPA: Latent Dynamics Consistency for Zero-Shot Physics Generalization

SemiGroup-JEPA (SG-JEPA), which extends the LeWorldModel framework by supplying the parameter governing the physics to the temporal model via action-conditioning and jointly training an encoder and predictor through an autoregressive latent rollout, is introduced.
