About Claude Opus 4.7

Claude Opus 4.7 is Anthropic's mid-cycle Opus refresh, aimed at extending the lead on coding agents and long-running tool use established by Opus 4 and 4.5. Real-world deployments at Cursor, Cline, and Anthropic's own Claude Code suggest the gains are most pronounced on multi-hour agent tasks where memory and recovery matter.

For writing, Opus 4.7 keeps the line's defining strength: a willingness to commit to a voice and stay there. It's the consensus pick for fiction, copy, and any work where prose quality matters more than retrieval bandwidth.

Pricing follows the Opus pattern, premium versus mid-tier, so most teams reserve Opus for the workloads that visibly benefit and run mid-tier (Sonnet) elsewhere.
