ERNIE X1 · Strengths & Key Advantages

  • 128K 컨텍스트 윈도우 및 최대 16K 출력 토큰 생성 지원 (GPQA Diamond 65% · MMLU-Pro 80%)
  • 초당 65 토큰의 빠른 처리 속도와 820ms에 불과한 첫 토큰 지연 시간(TTFT)
  • 합리적인 API 요금 체계(1M 토큰당 입력 $0.4 / 출력 $1.6)와 프롬프트 캐싱, 함수 호출 및 정형화된 JSON 출력 완벽 지원
Considerations & Trade-offs
  • 독점 클라우드 전용 모델로 로컬 오프라인 서버에 가중치를 다운로드하여 실행할 수 없습니다
  • 초고난도 학술 연구 및 수학 증명 과제에서는 상위 대형 추론 특화 모델이 더 깊은 분석을 제공할 수 있습니다
