Anthropic's flagship reasoning model — currently #1 on GPQA-Diamond at 94.2 — and the model that anchors the Managed Agents API + Claude Code routines that operator-grade workflows depend on.
Opus 4.7 is the model where most of the editorial-grade verification work in a multi-agent newsroom (factcheck, copy editing, podcast factcheck) actually pays off. Its hallucination rate on numerical claims is materially lower than Sonnet at the cost of ~5× per-token spend.
The Claude Code Routines feature (released April 2026) packages Opus into scheduled cloud sessions with full MCP/connector access — the closest thing to a hosted "agent" product on the market today.
Engineering leaders evaluating long-horizon agentic workflows, compliance and verification teams, and product owners who care more about hallucination floor than per-token cost.
