PFLM Predicts Language in Context Without Prior Text Training
October 4, 2026
The Prior-Fitted Language Model (PFLM) is a 300M-parameter transformer trained exclusively on synthetic non-linguistic priors. It learns to predict real languages in-context by inferring statistical signatures from a prefix, achieving significant bits-per-byte improvements over uniform baselines.
