AI에게 질문해서 답을 얻는 것과, 일을 맡기는 것은 다릅니다. 질문은 답이 오면 끝나지만, 일은 여러 단계를 거쳐야 끝납니다. 계약서를 검토하고, 여러 파일의 숫자를 대조하고, 중간 결과를 검증한 뒤 다음 단계로 넘기는 식입니다. 한 단계에서 잘못된 값이 나오거나 작업이 멈추면, 결국 사람이 전체를 처음부터 다시 확인해야 합니다. Solar Pro 4는 이 과정을 기준으로 만들었습니다. Solar Pro 3와 비교하면 에이전트 능력이 크게 향상되었고, 긴 문서, 터미널 작업, 멀티턴 도구 사용처럼 실제 업무와 가까운 평가에서 개선 폭이 특히 두드러집니다. 그리고 근거가 없으면 답을 지어내는 대신 확인할 수 없다고 답합니다. [ Upstage Console에서 Solar Pro 4 시작하기 ] Solar Pro 4는 512K 컨텍스트와 최대 128K 출력을 지원합니다. 계약서, 보고서, 데이터 파일 여러 개를 나누지 않고 한 세션에 넣고 작업하는 에이전트 업무의 기본 조건입니다. 입력과 출력 모두 영어, 한국어, 일본어를 지원하며, 응답 속도는 reasoning effort로 조절합니다. 깊은 추론이 필요한 작업은 높게, 실시간 응대가 필요한 작업은 낮게 설정하면 되고, 낮은 effort에서는 일반 챗봇 수준의 속도로 응답합니다. 모델의 상세 스펙은 개발자문서 에서 확인할 수 있습니다. Solar Pro 3에서 Solar Pro 4로: 에이전트 능력의 도약 개선 폭이 가장 큰 곳은 실무 성패를 가르는 에이전트 평가입니다. 터미널 작업 (Terminal-Bench v2.1) : 12 → 57, 약 4.8배 멀티턴 도구 사용 (τ³-Banking) : 9 → 23, 약 2.6배 긴 문서 추론 (AA-LCR) : 31 → 71, 약 2.3배 이번 개선에는 업스테이지가 구축해 온 OfficeVerse가 큰 역할을 했습니다. Solar Open 2 개발 단계부터 만들어 온 자체 파이프라인으로, 실제 공개 데이터를 기반으로 11개 산업 도메인, 12개 태스크 유형의 사무 업무를 합성하고 작업마다 성공과 실패를 채점합니다. 분석 업무는 Excel로, 발표 업무는..."},"evidence_pages":[],"related_signals":[{"id":"fa3a27b2-c4c7-4160-8ce0-239c50019177","url":"https://onlylabs.fyi/signals/fa3a27b2-c4c7-4160-8ce0-239c50019177","source_url":"https://www.upstage.ai/blog/en/solar-pro-4","title":"Solar Pro 4","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"upstage","name":"Upstage (Solar)","category":"neolab"},"occurred_at":"2026-08-28T04:26:45.753+00:00","first_seen_at":"2026-08-11T08:03:38.902635+00:00","date_source":"sitemap.lastmod"},{"id":"c4b470a9-9408-491f-96e4-ddd9507a90b8","url":"https://onlylabs.fyi/signals/c4b470a9-9408-491f-96e4-ddd9507a90b8","source_url":"https://www.upstage.ai/blog/ja/studio-demo-insurance","title":"Studio Demo Insurance","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"upstage","name":"Upstage (Solar)","category":"neolab"},"occurred_at":"2026-08-24T07:11:39.585+00:00","first_seen_at":"2026-08-24T08:01:45.754922+00:00","date_source":"sitemap.lastmod"},{"id":"a71ac55b-0d1b-4d08-955a-ac5b867ec6b2","url":"https://onlylabs.fyi/signals/a71ac55b-0d1b-4d08-955a-ac5b867ec6b2","source_url":"https://www.upstage.ai/blog/ko/console-kr-sp4","title":"Console Kr Sp4","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"upstage","name":"Upstage (Solar)","category":"neolab"},"occurred_at":"2026-08-13T00:00:00.000Z","first_seen_at":"2026-08-20T08:00:51.452146+00:00","date_source":"page.visible_date"},{"id":"4a84fb5c-a7da-4b15-927d-59a06982fc36","url":"https://onlylabs.fyi/signals/4a84fb5c-a7da-4b15-927d-59a06982fc36","source_url":"https://www.upstage.ai/blog/ja/hokenmainichi-vol5","title":"Hokenmainichi Vol5","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"upstage","name":"Upstage (Solar)","category":"neolab"},"occurred_at":"2026-08-05T09:50:44.573+00:00","first_seen_at":"2026-08-20T08:00:51.452146+00:00","date_source":"sitemap.lastmod"},{"id":"31b93b05-3910-498c-951a-63c73752f448","url":"https://onlylabs.fyi/signals/31b93b05-3910-498c-951a-63c73752f448","source_url":"https://www.upstage.ai/blog/en/solar-open-2","title":"Solar Open 2","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"upstage","name":"Upstage (Solar)","category":"neolab"},"occurred_at":"2026-08-05T05:13:13.402+00:00","first_seen_at":"2026-07-23T04:01:46.348984+00:00","date_source":"sitemap.lastmod"},{"id":"5f45ff9a-a686-4b5d-a931-9c87af544149","url":"https://onlylabs.fyi/signals/5f45ff9a-a686-4b5d-a931-9c87af544149","source_url":"https://www.upstage.ai/blog/ko/solar-open-2","title":"Solar Open 2","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"upstage","name":"Upstage (Solar)","category":"neolab"},"occurred_at":"2026-08-05T05:13:13.402+00:00","first_seen_at":"2026-08-20T08:00:51.452146+00:00","date_source":"sitemap.lastmod"}]}
