Models answer Korean questions on vocabulary, history, general knowledge and reading comprehension. It tests cultural and contextual knowledge that translated benchmarks miss.

Launch posts usually cite version 1.1 of the dataset.

In the authors’ words

Large language models (LLMs) trained on massive corpora demonstrate impressive capabilities in a wide range of tasks. While there are ongoing efforts to adapt these models to languages beyond English, the attention given to their evaluation methodologies remains limited. Current multilingual benchmarks often rely on back translations or re-implementations of English tests, limiting their capacity to capture unique cultural and linguistic nuances. To bridge this gap for the Korean language, we introduce the HAE-RAE Bench, a dataset curated to challenge models lacking Korean cultural and contextual depth. The dataset encompasses six downstream tasks across four domains: vocabulary, history, general knowledge, and reading comprehension. Unlike traditional evaluation suites focused on token and sequence classification or mathematical and logical reasoning, the HAE-RAE Bench emphasizes a model's aptitude for recalling Korean-specific knowledge and cultural contexts. Comparative analysis with prior Korean benchmarks indicates that the HAE-RAE Bench presents a greater challenge to non-Korean models by disturbing abilities and knowledge learned from English being transferred.

Solar Pro 2 leads with 86.2% among models released by July 2026

Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

The newest model with a score here came out in July 2026, and nobody has reported a newer one. Among the 20 highest-ranked models on the capability index, these have no score yet:

  1. 1 Solar Pro 2 86.2%
  2. 2 Solar Open 2 73.8%
  3. 3 Solar Open 100B 73.3%

Number one over time

Lab claims count from the day the card came out, independent runs from the model’s release.

Upstage’s own number for Solar Pro 2 passed 85% in July 2025

All the scores we have, one dot each, so a model tested at several settings appears more than once.
