anthropic/claude-opus-5
Anthropic's current flagship Opus and the successor to Opus 4.8, at the same price. Built for complex agentic coding and enterprise work: multi-file features, large refactors, and long autonomous runs it finishes rather than leaving half-done. Deep reasoning is on by default, with a 1M-token context window and native prompt caching. Pick it when the task is hard and the output has to be right.
