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 的綜合指南，這是 Anthropic 最智能的模型，具有用於推理控制的工作量參數。涵蓋模型功能、基準、工作水平（高/中/低）、混合推理和模型選擇。在使用 Opus 4.5、優化推理深度、選擇模型或了解工作量參數權衡時使用。 來源：adaptationio/skrillz。
