Anthropic pitches Sonnet 5.5 as the everyday AI model that costs less to use

Anthropic has released Claude Sonnet 5.5, the mid-range model in its AI lineup aimed at routine professional work rather than the hardest, most open-ended problems. The company says it produces answers about 30% faster than Sonnet 5 and can cut the cost of a completed task by up to 30%, while keeping the listed per-token price unchanged. The claimed savings come from needing less text processing and fewer calls to outside tools to finish work such as debugging software or making documents, slides, and spreadsheets. That distinction matters for businesses: the competition is increasingly about the cost and speed of getting useful work done, not just the headline price of an AI model.
