The company also said the model generates output more than 30% faster than its predecessor.\n\nThe new [model](https://qazinform.com/tag/artificial-intelligence) is designed for complex tasks including coding, computer use, research and business workflows. Anthropic said early testers used Opus 5.5 for large-scale code migrations, software audits and other projects that previously required substantially more time and computing resources.\n\nOpus 5.5 costs $4 per million input tokens and $20 per million output tokens, compared with $5 and $25, respectively, for Opus 5. Cache reads cost $0.20 per million tokens, down from $0.50.\n\n[Anthropic](https://qazinform.com/tag/anthropic) said Opus 5.5 also achieved its strongest results to date on the company’s automated behavioral audit, which evaluates models across thousands of simulated scenarios. The company has introduced additional safeguards for [cybersecurity](https://qazinform.com/tag/cybersecurity), biology and protection against model distillation.\n\nClaude Opus 5.5 is available today.
