Artificial Analysis: Claude Sonnet 5.5 Reaches Opus-Level Performance With Record Token Use
Artificial Analysis evaluated Claude Sonnet 5.5 and found it nearly matches Opus 5.5 across benchmarks while outputting up to 193,000 tokens per task at max effort. This token explosion drives task costs up to $7.60, roughly 50% higher than Sonnet 5 despite unchanged token pricing. Teams routing agentic workflows must balance high reasoning quality against significantly inflated output volume.
