  We introduce HyperCLOVA X, a family of large language models (LLMs) tailored
to the Korean language and culture, along with competitive capabilities in
English, math, and coding. HyperCLOVA X was trained on a balanced mix of
Korean, English, and code data, followed by instruction-tuning with
high-quality human-annotated datasets while abiding by strict safety guidelines
reflecting our commitment to responsible AI. The model is evaluated across
various benchmarks, including comprehensive reasoning, knowledge, commonsense,
factuality, coding, math, chatting, instruction-following, and harmlessness, in
both Korean and English. HyperCLOVA X exhibits strong reasoning capabilities in
Korean backed by a deep understanding of the language and cultural nuances.
Further analysis of the inherent bilingual nature and its extension to
multilingualism highlights the model's cross-lingual proficiency and strong
generalization ability to untargeted languages, including machine translation
between several language pairs and cross-lingual inference tasks. We believe
that HyperCLOVA X can provide helpful guidance for regions or countries in
developing their sovereign LLMs.
