Upstage has earned global recognition with its latest proprietary large language model (LLM), Solar Pro 2, which was recently named one of the top 10 “Frontier Models” by leading AI benchmark organization Artificial Analysis.
It is the only model developed in Korea to be included in the index, placing Upstage alongside industry leaders such as OpenAI, Google, Meta, and Anthropic.
Artificial Analysis’ Intelligence Index is regarded as one of the most comprehensive public evaluations of language model performance.
The index assesses over 200 models using seven key benchmarks—including reasoning, coding, general knowledge, and advanced math—to generate a composite score that reflects multiple dimensions of intelligence.
Solar Pro 2 achieved a score of 58, outperforming widely used models such as GPT-4.1 (53), GPT-4o (41), and LLaMA 4 Maverick (51).
It also surpassed notable newcomers such as Kimi-K2 (57.59) and DeepSeek V3 (53)—a significant achievement for a model with just 31 billion parameters.
In contrast, many of the models it surpassed or matched operate at 100B+ scale, with the top-ranked Grok-4 reportedly reaching 1.7 trillion parameters.
