Exciting new research led by @lorenz_wlf to accelerate RL task generation using mech interp methods in collaboration with @GoodfireAI
Training a model to generate RL tasks not too hard, not too easy costs many solver runs per task.
PROPEL predicts difficulty via a probe on its activations instead, amortizing cost and speeding up generator optimization.
New open-ended RL research from @vmax + @GoodfireAI.
