What is Claude Opus 5? Same-price upgrade — should you switch now?
Summary in three lines
- Claude Opus 5 (July 24, 2026) costs the same as Opus 4.8 and passed automation tests at 1.5x the runner-up's rate.
- An effort setting lets you choose fast and cheap for urgent tasks or slower and more careful for important ones.

What we learned
- How you hand off work often matters more than the model. If results disappoint, rewrite the order, criteria and examples in your instructions before switching.
- Give the same routine task to your current AI and the new one, and ask each to say honestly what went well and what fell short. It takes ten minutes.
