Amin Sghaier, Ali Parviz, and Alexia Jolicoeur-Martineau introduce Probabilistic Tiny Recursive Models, a train-free extension to Tiny Recursive Models that reaches 91.2 percent accuracy on PPBench puzzles

Gains reach up to 51 points on hard puzzles without retraining.

Very cool train-free extension to TRM. By injecting noise into the latent space, TRMs can explore a wider set of basins, and the exit head can then identify which trajectories succeeded. Feels like unlocking an entirely new scaling axis. Awesome work! 🔗https://arxiv.org/pdf/2605.19943

Project with students I have been supervising these past few months: Simple test-time-compute method to massively boost TRM accuracy. It can be used without retraining.

Test-time scaling for Tiny Recursive Models (TRM) without retraining or task-specific augmentation. Just K parallel rollouts with noise in the latent, the existing Q head selects among them Boosts pretrained TRM by up to 51 points on hard puzzles! https://amins01.github.io/ptrm 🧵1/N
