Performance Summary
Claude Opus 4, released on May 22, 2025, is positioned as a leading AI model, particularly in coding and complex agent workflows. While its speed performance is moderate, ranking in the 29th percentile, it demonstrates exceptional reliability, achieving a perfect 100th percentile, indicating minimal technical failures and consistent evaluable responses. However, its pricing is at a premium level, placing it in the 4th percentile for cost competitiveness. The model excels across several benchmark categories. It achieved perfect 100% accuracy in both Ethics (Baseline) and General Knowledge (Baseline), often being the most accurate and fastest among models at its price point in these areas. Its coding capabilities are strong, with 94% accuracy in the Coding (Baseline) benchmark, aligning with its claim as a top coding model. Reasoning (Baseline) also shows high proficiency at 98% accuracy. Instruction Following (Baseline) is solid at 71% accuracy, and Email Classification (Baseline) is competent at 97%. Opus 4's key strengths lie in its high accuracy across diverse cognitive tasks, particularly in ethics, general knowledge, coding, and complex reasoning, coupled with its outstanding reliability. Its primary weakness is its premium pricing, which may limit accessibility for some users.
