Anthropic released Sonnet 5.5 at $2 and $10 per million input and output tokens, half the Opus 5.5 rate. How much a buyer saves by moving work down a tier depends on tokens burned per task and on cache reads priced identically on both models.

Anthropic says Sonnet 5.5 nearly ties Opus 5.5, 1,844 to 1,846, on an everyday-work benchmark while running more than 30% faster than Sonnet 5. For teams paying double per token for Opus, Sonnet becomes the sensible default, with Opus kept for long, ambiguous jobs.
