Neural Scaling Laws

Definition

Neural scaling laws are predictable mathematical relationships linking an AI model's performance to its size, training data volume and compute budget.

Frequently Asked Questions

Do scaling laws still hold in 2026?
Generally yes, but with nuances. Classic scaling laws (more compute = better model) still hold, but marginal returns are diminishing. Inference-time scaling laws (test-time compute) represent a new optimization frontier.
What does the Chinchilla law predict?
The Chinchilla law (DeepMind, 2022) predicts that an optimally trained model should have roughly 20 tokens of data per parameter. This means a 70 billion parameter model should be trained on about 1.4 trillion tokens to be compute-optimal.
