Claude Opus
Anthropic's most capable model. Built for frontier coding, AI agents, and the work where precision and sustained effort matter most.
Built for work that demands judgment
When the stakes are high and shortcuts are expensive, Opus is the right tool.
Adaptive Thinking
Automatically adjusts how much reasoning it applies based on task complexity. Plans carefully, runs for longer, and catches its own mistakes across large multi-step workflows.
Production-Ready Code
Writes code with minimal oversight across large codebases. Plans carefully, executes with sustained effort, and self-corrects. 70% clearance rate on CursorBench vs. 58% for the previous version.
AI Agent Orchestration
Handles multi-tool coordination, memory across sessions, and autonomous multi-step workflows. Resolves 3x more production tasks than the previous version in independent benchmarks.
Long-Document Analysis
1M token context window. Reads and synthesizes entire contracts, reports, and research papers without losing track. 90.9% accuracy on the BigLaw Bench legal document benchmark.
