Claude Opus
Model ● Covered in 37 stories + Follow
Claude Opus is an Anthropic model used across multiple AI systems and cited in recent coverage as part of discussions about model capability access, misuse, and operational deployment. Coverage from Anthropic describes it as one of the Claude models targeted in threat-intelligence cases involving cyber, surveillance, biological misuse, conventional weapons, illicit distillation, and other malicious requests, with Anthropic reporting disrupted activity and strengthened safeguards. Separately, Opus is mentioned in reporting on tooling and workflow optimization in coding and code review, where it has been used as a lead agent and as a planning model within hybrid agent systems.
