**[Anthropic Launches Claude Sonnet 5.5: Over 30% Speed Increase and 30% Cost Reduction]** According to Golden Finance, on September 29, Anthropic unveiled its next-generation AI model, Claude Sonnet 5.5, claiming that the model achieves over a 30% increase in operational speed and up to a 30% reduction in task execution costs compared to its predecessor, Sonnet 5. Sonnet 5.5 is positioned as a mid-range model within the Claude 5.5 series, primarily designed for tasks such as daily work, code debugging, document creation, presentations, and spreadsheet production. Anthropic stated that Sonnet 5.5 demonstrated significant performance improvements across multiple tests, scoring 70.6% in the Terminal-Bench 4.0 code test, which is 10.3% higher than Sonnet 5. The model also shows enhancements in long-duration tasks, image comprehension, and knowledge-based work. In terms of pricing, Sonnet 5.5 retains the same pricing structure as Sonnet 5: $2 per million input tokens, $10 per million output tokens, and $0.2 per million cached tokens. However, due to the model's improved efficiency, Anthropic claims that actual task costs can be reduced by up to 30%. Anthropic also noted that Sonnet 5.5 has upgraded its security capabilities, introducing network security measures similar to those used in high-performance models for the first time in the Sonnet series. The model is now available on the Claude platform and supports integration with Amazon Web Services (AWS), Google Cloud, and Microsoft Azure.
