Your last sentence mirrors my model choices recently. Opus can do things very well but Sol can do them well for less than 1/4 the price.

And 10x the time.

Sadly this.

Sol, write me a function that moves all the toothpicks from jar 1 to jar 2

>writing test harnesses

>writing tests

>450/450 offline tests pass

>1 toothpick moved...

>error in acceptance test, fixing...

>toothpick is one pixel from expected destination, restarting toothpick job

>THIS MODEL IS AT CAPACITY. PLEASE TRY ANOTHER MODEL.

It's not a mystery, artificial intelligence ranks opus exactly as 1/8 to 1/4th cheaper.
