# Luna Metrics Comparison

> Explore Galileo's preset Luna metrics for evaluating and improving AI system performance across multiple dimensions

Galileo provides a comprehensive suite of preset Luna metrics designed to evaluate various aspects of AI system performance without requiring custom implementation.These metrics span across the following categories:- [Agentic Performance Metrics](/concepts/metrics/agentic/agentic-overview)
- [Expression And Readability Metrics](/concepts/metrics/expression-and-readability/expression-and-readability-overview)
- [RAG Metrics](/concepts/metrics/rag/rag-overview)
- [Safety And Compliance Metrics](/concepts/metrics/safety-and-compliance/safety-and-compliance-overview)Each metric addresses specific evaluation needs, from measuring factual correctness to detecting potential biases or tracking tool usage effectiveness.These metrics apply to different node types (such as session, trace, or different span types), depending on the metric.Use the sortable, filterable table below to explore all available native metrics and find the right measurements for your AI applications. Hover over an icon in the **Modalities** column to see what it represents.

Category:
          \<select value={filterCategory} onChange={(e => setFilterCategory(e.target.value))}><option value="All">All Categories</option></select>


        

Node:
          \<select value={filterNode} onChange={(e => setFilterNode(e.target.value))}><option value="All">All Nodes</option></select>


        

Modality:
          \<select value={filterModality} onChange={(e => setFilterModality(e.target.value))}><option value="All">All Modalities</option></select>
