The updated mid-range model burns fewer tokens and responds faster, aimed squarely at enterprise cost-per-task economics rather than benchmark bragging rights.
Anthropic released Sonnet 5.5, the newest version of its mid-tier model, which the company says delivers faster response times and lower token consumption than its predecessor. Anthropic is framing it explicitly as a work partner, not a frontier showcase model.
The release lands as enterprises push back on rising inference bills and demand predictable per-task costs, a shift that's reshaping how labs position mid-range models against flagship releases.
Cost-per-task, not raw capability, is becoming the deciding factor in enterprise model procurement, and Anthropic is explicitly optimizing for that buyer. Teams running high-volume agentic workflows should re-run cost comparisons now that a cheaper, faster Sonnet tier exists.
