What is Synthetic Data?

Artificially generated data used to train AI models.

By Council Research TeamUpdated: Jan 27, 2026

Definition

Synthetic data is created by AI or algorithms rather than collected from the real world. It can supplement limited real data, protect privacy, or create training examples for rare scenarios.

Examples

1AI-generated training conversations
2Simulated medical records
3Procedurally generated images

Why It Matters

As real data becomes scarce, synthetic data is increasingly important for AI training—but quality concerns remain.

Related Terms

Fine-Tuning

Training an AI model on specific data to specialize it for particular tasks.

Model Collapse

Degradation that occurs when AI models are trained on AI-generated content.
