Claude 5.5 Models: Opus for Complexity, Sonnet for Most Use Cases

By PulseAugur Editorial · [1 sources] ·

A developer tested Anthropic's Claude 5.5 models (Opus 5.5, Sonnet 5.5, and Haiku 5.5) for production use cases, finding that while Opus 5.5 excels at complex tasks, Sonnet 5.5 offers a better balance of cost, speed, and accuracy for most common applications. Haiku 5.5, despite lower benchmark scores, proved surprisingly effective for real-time systems. The analysis emphasizes selecting a model based on specific use-case requirements rather than defaulting to the most powerful option. AI
