# RAG vs Fine-Tuning for Context

RAG retrieves docs at query time. Fine-tuning bakes knowledge into weights.

## Detailed Comparison

| Factor | RAG | Fine-Tuning | Winner |
|--------|------|------|--------|
| Data Freshness | Always up-to-date, retrieves latest docs | Frozen at training time, needs retraining | RAG |
| Cost | Low — embedding + vector DB | High — GPU hours for training | RAG |
| Accuracy | Depends on retrieval quality | Deep domain knowledge baked in | Fine-Tuning |
| Implementation | Moderate — chunking, embedding pipeline | Complex — curated dataset, training infra | RAG |
| Transparency | Can cite sources, show documents | Black box, no traceability | RAG |

## Key Statistics

- **86%** (2026)
- **10x** (2026)

## Choose RAG when...

- You want a versatile solution for various use cases.
- You need quick implementation.
- You prefer a simpler setup.

## Choose Fine-Tuning when...

- You are targeting specialized domains.
- You need tailored model performance.
- You want deeper customization options.

## Our Recommendation

RAG wins for most use cases. Fine-tuning for specialized domains.
