Claude Opus 4.5 represents Anthropic's most capable and intelligent model, released November 24, 2025. It combines state-of-the-art reasoning abilities with a revolutionary "effort parameter" that lets you control the model's reasoning depth and token consumption dynamically.

Key Positioning: Opus 4.5 is the best model in the world for complex coding, autonomous agents, computer use automation, and advanced reasoning tasks. It succeeds where previous models required manual intervention and replaces what previously demanded multiple specialized models.

Opus 4.5 isn't just an incremental improvement—it's a model tier reduction. Tasks requiring Opus 4.1 now run on Sonnet with Opus 4.5 for complex work. Budget-conscious teams use Opus 4.5's effort parameter instead of maintaining multiple model versions.

Claude Opus 4.5 的综合指南，这是 Anthropic 最智能的模型，具有用于推理控制的工作量参数。涵盖模型功能、基准、工作水平（高/中/低）、混合推理和模型选择。在使用 Opus 4.5、优化推理深度、选择模型或了解工作量参数权衡时使用。 来源：adaptationio/skrillz。
