FAQPage Schema
How do I design evaluation rubrics for LLM features?

Design evaluation rubrics by translating product goals into measurable criteria. This Skill generates rubrics and benchmarks that map directly to your LLM feature requirements, allowing you to evaluate model quality against specific product outcomes.

What's the best way to benchmark LLM outputs across iterations?

Benchmark LLM outputs by measuring performance against established rubrics and test cases. This Skill supports benchmarking across model iterations to track quality improvements and guide product decisions based on result analysis.

How do I generate test cases to uncover model weaknesses?

Generate test cases by creating diverse evaluation datasets tailored to your model feature. This Skill produces test cases designed to expose weaknesses in LLM outputs and provide actionable data for iterating on improvements.

Can I run end-to-end AI evaluations for product teams validating features?

Yes, you can run end-to-end AI evaluations tailored for product teams. This Skill plans an evaluation plan for a specific model feature and generates the necessary rubrics, test cases, and benchmarks to validate LLM functionality.

Why do I need a repeatable process to evaluate model quality?

A repeatable process to evaluate model quality ensures consistent measurement across updates. This Skill provides a structured approach to test-case generation and benchmarking, enabling teams to reliably assess LLM performance and iterate based on results.
