Anthropic Launches Claude Sonnet 5.5 with Over 30% Faster Output Generation

Anthropic has released its new AI model, Claude Sonnet 5.5, which delivers output generation speeds more than 30% faster than its predecessor. The model is optimized for cost-efficiency and performance in software development, agentic workflows, and document creation. While API pricing remains consistent at $2 per million input tokens and $10 per million output tokens, the company reports up to a 30% reduction in cost per task due to improved token efficiency. Claude Sonnet 5.5 is available across major cloud platforms and the Claude interface, with a Claude Haiku 5.5 model expected in the coming weeks.
