What is Claude Opus 5.5?

Claude Opus 5.5 is Anthropic’s high-capability AI model for advanced coding, research, business work, computer use, and extended agentic tasks. It is designed to operate effectively on large and complex workloads that require planning, sustained context, tool use, verification, and multiple execution steps. In software engineering, Opus 5.5 can be used for codebase-wide migrations, debugging, audits, optimization, code review, and other long-running development projects. The model also supports knowledge-intensive work such as financial analysis, legal research, spreadsheet creation, executive presentations, data collection, and professional reporting. Anthropic reports that Opus 5.5 improves both task efficiency and serving efficiency compared with Opus 5, including lower token usage, faster output, and reduced cost on typical workloads. Its writing and communication behavior has been updated to prioritize important information, reduce unclear phrasing, and better follow requested style constraints. Opus 5.5 also includes stronger safeguards for autonomous and tool-using scenarios, including action screening, improved prompt-injection resistance, sandbox support, and vulnerability detection during code review. Anthropic applies additional safeguards to cybersecurity, biology, and model-distillation use cases, with expanded access programs available to verified organizations in certain sensitive fields. The model supports zero data retention and includes watermarking measures intended to support compliance requirements such as the EU AI Act. Developers can access Opus 5.5 through the Claude Platform using the claude-opus-5-5 model, while Claude Code and other Anthropic products can use it for interactive and agentic work. Claude Opus 5.5 is also available through Amazon Web Services, Google Cloud, and Microsoft Azure for organizations that prefer to deploy through major cloud platforms.
