Frequently asked questions

What is the Omniscience benchmark?

AA-Omniscience (Artificial Analysis) measures factual-knowledge reliability and calibration across 6,000 questions in six domains. Its Omniscience Index rewards correct answers and appropriate abstentions while penalising confident wrong answers, so a model that guesses badly can score below zero.

Which AI model scores highest on Omniscience?

Claude Opus 5.5 (Anthropic) leads with 46.4, from $4.00 per 1M input tokens from Anthropic.

How many models are ranked on Omniscience?

378 models carry an Omniscience score. Scores come from Artificial Analysis; where a model has a listed API price it is drawn from LiteLLM and OpenRouter, and models with no current price are listed without one.
