The scaling laws of AI Why neural networks continue to grow
summary
Scaling laws show that bigger models plus bigger datasets reliably improve performance: examples include transformer families trained on billions of tokens and vision models trained on millions to billions of unlabeled videos, yielding qualitative jumps like one‑shot and few‑shot abilities. Engineering details: 175 billion parameters models outperform much smaller ones, require model‑ and data‑parallel transformer training, optimized libraries and GPU stacks, and massive labeling efforts (order 1,500 human labelers for complex driving data). Energy and implementation tradeoffs determine practical sweet spots.
