Claude Opus VS Claude Opus Agent

Whats the difference between the regular Claude Opus/Thinking and Claude Opus Agent? I notice I get this for implementing a Plan but does it cost more? Faster? Whats the difference?

Also when do you folks use OPUS vs SONNET?

Thanks for the help?

Hey there!

I’m not really sure what you’re talking about. When selecting a model, there’s just one Opus 4.5 (unless I’m really missing something!)

Can you share what you’re seeing?

Personally, I’m a big Opus fan – it both beats Sonnet in performance and uses less output tokens. That said, you should experiment with different models! My test tends to be “how often do I get something usable on the first try” – Opus does really well with that.
