Model Information
  • Coding: Claude Opus 5.5 is Anthropic's strongest Opus model for agentic coding. It handles long-running work in large codebases, including building features, debugging, refactoring, and code review. It finds the root cause before changing anything, checks its work as it goes, and explains its changes in plain language, so engineers can review and trust them quickly.
  • Agents: Claude Opus 5.5 is the Opus tier's strongest agentic model, reliably orchestrating complex multi-tool tasks. It plans deliberately, coordinates subagents, uses memory to learn across sessions, and drives long-running work forward with minimal oversight. Along the way, it reports back clearly on what it did, what it found, and what it needs next.
  • Enterprise workflows: Claude Opus 5.5 is built to be the enterprise daily driver, powering agents that run projects end-to-end. It follows instructions precisely, stays in scope, and produces professional-grade spreadsheets, slides, and docs that are ready to use.
  • Financial analysis: Claude Opus 5.5 brings deeper reasoning and precision to financial workflows. It reads dense filings, models, and charts accurately, carries context across an entire deal or reporting cycle, and handles the nuance of compliance-sensitive work, with clear summaries of what it found and how it got there.
  • Vision: Claude Opus 5.5 is Anthropic's best Opus model for vision. It reads dense documents, charts, screenshots, and diagrams at high fidelity, making it reliable for document extraction, visual analysis, and interpreting complex real-world imagery.
  • Computer use: Claude Opus 5.5 brings high-resolution vision and deep reasoning to computer use, handling multi-step tasks that span multiple applications and require planning and judgment.
