Anthropic's deepest-reasoning model; planning, complex synthesis.
Opus 4.7 is reserved for hard reasoning tasks: architectural planning, multi-document synthesis, complex root-cause analysis. Used selectively because of cost; commonly invoked via a router that escalates from Sonnet when confidence is low.
Strengths
- Deepest reasoning of the Claude family
- Best for ambiguous, planning-heavy tasks
Tradeoffs
- Highest cost tier — not viable as default model
- Higher latency than Sonnet / Haiku
