Anthropic releases Claude Sonnet 5.5
Editorial Analysis
Anthropic launched Claude Sonnet 5.5 as the second model in its Claude 5.5 family, positioned as a faster and more cost-efficient option for everyday enterprise tasks such as coding, document creation, and spreadsheet work. Pricing remains at $2 per million input tokens and $10 per million output tokens, with claims of fewer tokens needed for equivalent work. The release expands Anthropic’s product lineup ahead of its planned IPO.
