Weaknesses
- Highest cost per token in the Claude line — use a router to reserve it for hard tasks
- Slower than Sonnet or Haiku for short, simple requests
Best for
- Architectural code reviews
- Long-document analysis and synthesis
- Agent planning and hard reasoning steps
- Customer escalations that need a careful answer
When to use Claude Opus 4.7
Use Opus 4.7 when the cost of a wrong answer is much higher than the cost of a few extra cents of inference. Typical fits: code review on a security-sensitive repo, summarising a long contract or RFP, planning an agent loop, or answering customer questions where the wrong answer has a real downside.
When not to use it
Do not run Opus 4.7 on classification, simple extraction, or high-volume routing tasks. Those should go to Haiku 4.5 or Sonnet 4.6. A good router sends 10–20% of traffic to Opus and the rest to smaller models, keeping quality high and cost sane.
