Claude Sonnet 4.6 and Claude Opus 4.6 are no longer Anthropic’s newest models.<\/strong> Sonnet 5 and Opus 5 now lead their respective families, but the 4.6 comparison still matters for teams maintaining older model IDs, estimating historical API costs, or deciding whether a migration is worth the work.<\/p>\n\n\n\n

The practical difference inside the 4.6 generation is simpler than the old marketing language suggested. Sonnet was the lower-cost, speed-oriented workhorse. Opus was the premium option for harder reasoning, long-running agents, and high-value professional work. At standard API rates, Opus cost about 1.67 times as much as Sonnet\u2014not five times as much.<\/p>\n\n\n\n
