However, I am also confused about market positioning. Too expensive to perform daily tasks - open souce models are much cheaper - and not frontier model to address complex real world problems.
Rarely used Sonnet btw.

Alternatively you can draw a horizontal "constant performance" line and see that Opus is cheaper for a given performance level.
There is a real advantage, especially for businesses, in using an off the shelf solution from a corporate provider.
Personally, the advantage of not having to set up multiple solutions from multiple sources outweighs the cost of a $20 a month subscription. Think about why a lot of consumers prefer Apple devices over Linux. There are a lot of advantages to Linux, but "never having to think about my tools" is its own advantage.
