Sonnet 5.5 vs. Opus 5.5 API Test: Methodology and Findings

By PulseAugur Editorial · [1 sources] ·

A developer conducted a comparative test of Anthropic's Sonnet 5.5 and Opus 5.5 models using an OpenAI-compatible API. The test involved 132 API calls across 22 tasks, including common development challenges and more complex problems like suffix arrays and token bucket limiters. While both models performed equally on verifiable tasks, Opus 5.5 was slower and generated more text. The developer emphasized the importance of a rigorous testing methodology, including pre-defined rules and transparent documentation of any adjustments made post-run. AI
