From Next Token Prediction to (STRIPS) World Models

Carlos N\'u\~nez-Molina, Hector Geffner, Vicen\c{c} G\'omez

Next-token prediction on action traces yields STRIPS world models accurate enough for planning on unseen states and goals.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Both the STRIPS Transformer and a standard transformer with stick-breaking attention can be used to produce models that support planning with off-the-shelf STRIPS planners over exponentially many unseen initial states and goals.

C2weakest assumption

The learned next-token models are sufficiently accurate and complete to serve as drop-in STRIPS action models for arbitrary unseen states and goals, with correctness evaluated exactly in the symbolic setting (abstract, evaluation section implied by results on generalization and planning performance).

C3one line summary

Transformers trained via next-token prediction on action traces can learn STRIPS action models that support planning over exponentially many unseen initial states and goals.
