What is MILU?

Multilingual knowledge-and-reasoning evaluation reported in Anthropic's Claude Opus 4.8 system card.

Tier A

A

Widely used: a lab reports it, or 50 or more models are scored on it.

How much stands behind a tier: usage, who backs it, a confirmed line from its own site or paper, and a clear read on X. High with three of the four, medium with two, low otherwise.

  • 13 models scored
  • reported by Anthropic
  • in curated RL directories (2 pts)

On X · unclear, low buzz, from 2 posts about MILU in the last month

MILU appears mainly as a data source in a small Tamil benchmark project, where Gemini 3.8 Flash scores 94.5% on MILU MCQs; there is little other discussion.
