anthropic/claude-opus-4-5

Claude Opus 4.5 is Anthropic's frontier reasoning model, optimized for complex software engineering, agentic workflows, and long-horizon computer use. It offers strong multimodal capabilities, competitive coding and reasoning performance, and improved robustness to prompt injection, with a verbosity control (low, medium, or high) to trade off speed, depth, and token usage. It supports advanced tool use, extended context management, and coordinated multi-agent setups for autonomous research, debugging, and multi-step planning.
