Anthropic adds a cheaper, faster Sonnet 5.5 to its Claude 5.5 family
Anthropic launched Claude Sonnet 5.5, the second model in its Claude 5.5 family, describing it as a faster and lower-cost complement to the flagship Opus 5.5 rather than a capability step. The company says it runs about 30 percent faster than Sonnet 5 and cuts cost per task by up to 30 percent for typical use. The launch lands while Anthropic is preparing a public listing and a week after it released Opus 5.5.
