Review the complete breakdown below to determine which model best fits your performance and budget requirements.
10 direct benchmark disciplines evaluated across capability, speed, and cost
Google experimental reasoning model that visualizes thoughts in real-time.
Fast Google frontier-adjacent model. Near-top official SWE-bench at a fraction of Opus price.
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.
