Anthropic released Claude Opus 5.5, delivering Fable 5.1-level agentic coding performance at ~40% lower cost than Opus 5, with input pricing at $4/million tokens and cache reads slashed 60% to $0.20/million tokens. The model excels in long-form code work (680K-line migrations completed in <1 day) and computer use tasks (81.8% on OSWorld 2.0), making it cost-effective for Thai tech teams and SMEs running autonomous agents and large codebase operations. Cache cost reduction particularly benefits production agentic workflows.
