What is LLM Judge Index™?

QUICK ANSWER

Our proprietary composite score ranking LLMs across 6 evaluation dimensions on a 0-100 scale.

Definition

The LLM Judge Index is the proprietary composite evaluation score developed by LLMJudge.com. It combines automated benchmark results, API performance data, community preference votes, and editorial assessment into a single 0-100 score.

How It Works

The Index formula weights six dimensions: Accuracy (20%), Reasoning (20%), Coding (18%), Safety (15%), Instruction Following (15%), and Creativity (12%). For industry-specific evaluations, different weights are applied to reflect unique requirements.

Example

Claude Opus 4 holds the highest LLM Judge Index score at 96.0. DeepSeek V3 scores 85.5 but at 1/30th the cost.
