Anthropic: Claude Opus 4.7

Anthropic's Claude Opus 4.7, released April 16, 2026, is designed for long-running, asynchronous agents, building on its predecessors' coding and agentic strengths. It performs among the fastest models, typically ranking in the top tier for speed (60th percentile). However, its pricing is positioned at premium levels (8th percentile), making it a high-cost option. A significant strength is its exceptional reliability, boasting a 99% success rate across benchmarks, indicating minimal technical failures. Opus 4.7 demonstrates strong performance in several key areas. It achieves perfect accuracy in General Knowledge and Ethics, with the former also being the most accurate at its price point and speed. Instruction Following, Coding, Reasoning, and Mathematics all show high accuracy, ranging from 80% to 98%, placing it in the top quartiles for these categories. A notable weakness is its performance in Hallucinations, where it achieves 90% accuracy, placing it in the 37th percentile, suggesting room for improvement in acknowledging uncertainty. Email Classification is moderate at 98% accuracy (51st percentile). Overall, Opus 4.7 excels in complex cognitive tasks and reliability, though its premium cost and moderate hallucination control are points to consider.
