Synthetic Data

Overview

Synthetic data is generated data intended to approximate properties of real-world datasets.

Why it is hyped

  • privacy constraints make real data hard to share
  • many domains have data scarcity
  • synthetic data can be scaled and tailored for specific tasks

Risks

Overuse of synthetic data can create feedback loops:

  • hallucinations propagate into training sets
  • model diversity can collapse over generations
  • rare / long-tail knowledge can be lost

Industry signal

Wired reported NVIDIA’s acquisition of synthetic-data startup Gretel as part of a broader push into synthetic-data tooling.
