10 direct benchmark disciplines evaluated across capability, speed, and cost
Baidu current multimodal enterprise foundation model with broad Chinese knowledge.
OpenAI cost-efficient reasoning model with adjustable thinking effort and top coding benchmark scores.
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.
