Pairwise benchmark snapshot · Aug 1, 2026
In this head-to-head showdown, GPT-5 delivers higher overall intelligence and human-preferred responses (Elo 1,558 vs 1,248), while GPT-5 leads in SWE-bench software engineering benchmarks (68.4%), while GPT-5 is more budget-friendly at $20/1M 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
Original Claude 3 flagship. Kept so opus 3 vs later Opus and vs GPT-4o still resolve.
OpenAI flagship reasoning model for 2025–26. Strong general preference Elo and multimodal coverage.
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.
