Shortcut models enable scaling offline RL, both at train-time at test-time! We beat so many other algorithms on so many tasks we had to stick most of the results in the appendix 😅. Very proud of @nico-espinosa-dice.bsky.social for spearheading this project, check out his thread!

by incorporating self-consistency during offline RL training, we unlock three orthogonal directions of scaling: 1. efficient training (i.e. limit backprop through time) 2. expressive model classes (e.g. flow matching) 3. inference-time scaling (sequential and parallel)

Excited to share our new paper, "Efficient Imitation Under Misspecification" @gokul.dev's thread ↓
