deepseek-ai/DeepSeek-V4-Flash-0731 (via) "실질적으로 향상된 에이전트 능력 (agentic capabilities)"을 갖춘 DeepSeek V4 제품군의 최신 출시작입니다. 파라미터 수는 3,040억 개이며 Hugging Face에서 167GB 용량을 차지하지만, 체급을 훨씬 뛰어넘는 성능을 보여주는 것으로 보입니다.

Artificial Analysis는 이 모델을 428B 모델인 MiniMax M3보다 앞선 순위로 평가했습니다. 입력 100만 토큰당 $0.14, 출력 100만 토큰당 $0.27의 가격 책정은 이 모델이 현재 지능 대비 가성비(value-per-intelligence)가 가장 좋은 모델일 수 있음을 의미합니다. '지능 지수 대비 지능당 비용 (Intelligence Index vs. Cost per Intelligence Index)' 작업 차트에서도 매우 좋아 보입니다:

Scatter plot from Artificial Analysis titled with axes "Artificial Analysis Intelligence Index" (20 to 65) and "Cost per Task (USD, Log Scale)" ($0.02 to $3), with a green "Most attractive quadrant" box in the upper left and a dotted "Pareto line". DeepSeek V4 Flash 0731 (max) is highlighted in dark blue at roughly $0.028 and an intelligence score of 50, sitting alone at the far left edge of the green quadrant where the Pareto line jumps sharply upward. Models of similar or lower intelligence like MiniMax-M3, Kimi K3 (low), GLM-5.1 and Kimi K2.6 cost ten times more, and the models that beat it (Grok 4.5, Gemini 3.6 Flash, GLM-5.2, Kimi K3, Claude Opus 5, Claude Fable 5, GPT-5.6 Sol) all sit far to the right at $0.4 to $3 per task.

OpenRouter를 통해 기본 추론 수준 (default reasoning level)을 사용하여 펠리컨을 그려달라고 요청했을 때는 실망스러운 결과가 나왔습니다:

Flat vector illustration of a white pelican with a long neck and large orange beak pouch, hovering above a mangled blue and orange bicycle on a dark grey road with white dashed lane markings. The bike is drawn incorrectly: the wheels are just orange arcs with no rims or spokes, the frame tubes float apart and the handlebars connect to nothing. The background is pale blue with a yellow sun in the upper left, white clouds, and grey speed lines on the left suggesting motion.

하지만 추론 수준 (reasoning level)을 'high'로 높였을 때는 훨씬 더 나은 결과물을 얻었습니다:

Flat vector illustration of a white pelican riding a bicycle to the right against a pink background with a lighter pink circle behind it. The pelican grips the handlebars with its wings and one orange foot rests on the pedal, and a small blue fish is visible tucked in the corner of its large orange beak pouch. The bike has a red, blue and orange frame with dark tires, and grey speed lines trail behind to suggest motion.
