I'm a total noob here, but just pointing out that Omniscience Index is roughly "Accuracy - Hallucination Rate". So it simply means that their Accuracy was very high.

> In the Hallucination Rate vs. AA-Omniscience Index chart, it’s not in the most desirable quadrant

This doesn't mean much. As long as Gemini 3 has a high hallucination rate (higher than at least 50% others), it's not going to be in the most desirable quadrant by definition.

For example, let's say a model answers 99 out of 100 questions correctly. The 1 wrong answer it produces is a hallucination (i.e. confidently wrong). This amazing model would have a 100% hallucination rate as defined here, and thus not be in the most desirable quadrant. But it should still have a very high Omniscience Index.
