Meta paper reveals Chinchilla scaling law blind spot, Skaling cuts error

A new Meta FAIR paper identifies a blind spot in the Chinchilla scaling law that leads to expensive mispredictions when extrapolating to frontier scales. Chinchilla assumes model size and training data contribute separately, but experiments show they influence each other's utility.
The proposed method, Skaling, adds just one extra term to capture this coupling, reducing prediction error by 1.5–3× and achieving full-grid Chinchilla-level accuracy with roughly 10× less profiling compute. On the Farseer dataset at 2×10^25 FLOPs, Chinchilla points to 380 tokens per parameter, while Skaling and direct estimates land around 20–40.
