Pairwise benchmark snapshot · Aug 1, 2026
In this head-to-head showdown, Gemini 3 Pro delivers higher overall intelligence and human-preferred responses (Elo 1,552 vs 1,362), while Gemini 3 Pro leads in SWE-bench software engineering benchmarks (72.4%), while Gemini 3 Pro is more budget-friendly at $5/1M per 1M output tokens. Review the complete breakdown below to determine which model best fits your performance and budget requirements.
9 direct benchmark disciplines evaluated across capability, speed, and cost
Hybrid-reasoning Sonnet from 2025. Kept for historical compare pages.
Google frontier multimodal model with a multi-million-token context window.
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.
