Sonnet 5 requires roughly 3x the agentic turns of Sonnet 4.6 on benchmarks like AA-Briefcase and GDPval-AA, and at max effort it takes around 6x more turns than at low effort.

Artificial Analysis found Sonnet 5 consumes far more agentic turns than its predecessor—about 3x more than Sonnet 4.6 on AA-Briefcase/GDPval-AA, and up to 6x more at maximum effort versus low effort—underlying the efficiency concerns that dampened the launch's reception. ✦ AI generated
