That is the standard pricing for Opus-class models these days.
Although given it's Musk, others may disagree.
It is price fixing, nothing else
I think at this point comparing raw token pricing is often apples to oranges.
When that isn't available, and the task involves "understanding the problem", "deciding what I'm actually after" etc. iterations, I find price-per-token to still be a better predictor of cost.
It’s still damned capable though, I’ve done a crazy amount of good work with 5.3 Flash.
