8 direct benchmark disciplines evaluated across capability, speed, and cost
DeepSeek open-weight Mixture-of-Experts coding model supporting 338 programming languages and 128k context.
Open-weights reasoning model trained with large-scale RL.
Simulate accuracy gains vs added response time & token cost
Reasoning models “think before answering” by generating internal reasoning tokens. Higher effort improves math, coding, and logic accuracy, but increases response delay and token costs.
