Synthetic Data
Synthetic Data is information artificially generated by AI to train other AI models, rather than collected from the real world. As we run out of high-quality human text on the internet, high-quality synthetic data becomes crucial.
Why it Matters
it allows models to learn specific skills (like coding or math) where human data is scarce or messy.
How It Works
- 1
Often produced using 'Model Distillation' (a smart model teaching a smaller model) or rigorous filtering pipelines.
- 2
The key challenge is avoiding 'model collapse,' where AI training on bad AI data leads to degradation.
Real-World Example
Llama 3.1 and DeepSeek V3 were trained on vast amounts of high-quality synthetic coding data generated by stronger models, allowing them to excel at programming tasks despite having fewer human coding examples.
