Don't forget that they want to make money in the end. They release small models for free because the publicity is worth more than they could charge for them, but they won't just give away models that are good enough that people would pay significant amounts of money to use them.
I got stuff done with Sonnet 3.7 just fine, it did need a bunch of babysitting, but still it was a net positive to productivity. Now local models are at that level, closing up on the current SOTA.
When "anyone" can run an Opus 4.5 level model at home, we're going to be getting diminishing returns from closed online-only models.
That's the tyranny of comfort. Same for high end car, living in a big place, etc.
There's a good work around though: just don't try the luxury in the first place so you can stay happy with the 9 months delay.
