Do you have to use Claude differently starting with Opus 5?

Anthropic has launched Claude Opus 5 as part of its fifth-generation Claude lineup.

The main takeaway is a shift away from using one “best” model for everything and toward choosing models by task, cost, and workflow fit.

Opus 5 is positioned for everyday enterprise work and agentic coding, while legacy prompting patterns with extra verification may now be unnecessary or inefficient.

Anthropic recommends simplifying prompts, removing redundant checks, and reworking harnesses and context engineering for the new model behavior.
