9 direct benchmark disciplines evaluated across capability, speed, and cost
Hybrid-reasoning Sonnet from 2025. Kept for historical compare pages.
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.
