As AI systems become more sophisticated, they rely on human knowledge to better understand context and the world.

- Optimize AI Performance: Evaluate and rank AI responses to improve the model's accuracy, fluency, and contextual relevance.
- Ensure Model Integrity: Test AI outputs for potential inaccuracies or biases, validating their reliability across use cases.
