Claude Opus 4.6

Model family: Claude
Claude Opus 4.6 is Anthropic’s latest and most capable Claude model, succeeding Opus 4.5 for the hardest reasoning and coding tasks. It powers multi-step agents that coordinate sub-agents and tools across big codebases and knowledge workflows, and in internal trials it autonomously discovered 500+ previously unknown high-severity security flaws in open-source libraries, highlighting its strength in cybersecurity analysis. Opus 4.6 is now the recommended top-tier model in the Claude lineup for Pro, Max, Team and Enterprise users who need deep, sustained reasoning on long-horizon business, legal, financial and engineering problems.
