Anthropic: Claude Opus 4.5
Analysis Summary
Claude Opus 4.5 is Anthropic's flagship reasoning model from late 2025, pairing strong general intelligence with one of the highest agentic scores in its class. It supports vision, tool use and function calling, giving it real breadth for both analytical and interactive business tasks.
It fits software engineering, multi-step agent workflows, and long-form client content where accuracy and tone control matter. Its 200K context window is smaller than some rivals, and newer Claude releases have since pushed reasoning further, but Opus 4.5 remains dependable for demanding professional use.
