9 direct benchmark disciplines evaluated across capability, speed, and cost
Open-weight-adjacent DeepSeek flagship. High reasoning density per dollar.
OpenAI largest dense non-reasoning model with expansive world knowledge and reduced hallucinations.
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.
