Overview
What Claude Opus 5 is
Anthropic positions Opus 5 for deep reasoning, long-horizon agent tasks, coding, vision, document work, code review, and multi-agent coordination. It supports effort controls and features such as mid-conversation tool changes, fallbacks, and fast mode on supported platforms.
Opus 5 remains available, but Anthropic has released Opus 5.5 at a lower published price. Buyers should compare both models on task quality, latency, migration constraints, and total token use rather than assume the older model is the better default.
