Solar Pro 2 대비 무엇이 달라졌나 Solar Pro 3는 Solar Pro 2와 유사한 수준의 처리 속도(TPS)와 비용 구조를 유지하면서, 실제 사용자 상호작용과 밀접한 영역에서 의미 있는 성능 향상을 달성했습니다. 특히 지시 이행 능력에서 52% 향상(IFBench 55.78), 복잡한 추론 작업에서 30% 향상(Arena Hard v2 62.5)을 기록하며, 실서비스 품질에 직접적인 영향을 미치는 영역에서 두드러진 개선을 보였습니다. 아래 그래프는 동일한 조건에서 Solar Pro 2와 Solar Pro 3를 비교한 결과입니다. 각 항목은 대표 벤치마크 점수를 기반으로 하며, 실제 API 사용 시 체감되는 추론 품질 차이를 보여주는 지표입니다.
