Do I need benchmark data or can I use my own test set?

You can use your own test set in most cases — you do not need benchmark data unless you specifically want to compare against a standard public baseline.
Use your own test set if:
- You care about your actual use case
- You want results that reflect your data distribution
- You need to measure performance on private, domain-specific, or proprietary data
- You’re evaluating a model for internal decision-making
Use benchmark data if:
- You want to compare your results to published numbers
- You need a standardized, widely recognized evaluation
- You want to show performance relative to other models in a common setting
- You’re doing research and need reproducibility
Best practice
If possible, do both:
- Benchmark for comparability
- Your own test set for real-world relevance
Important note
Whatever you use, make sure your test set:
- Is held out from training/tuning
- Represents the real deployment environment
- Has clear evaluation metrics
