> You don't see the same scale of excitement surrounding the open weight trillion+ parameter models because, while it's neat they're open weight, it doesn't mean a lot if you need $50k worth of computers to just barely run them.

This looks like a rather outdated POV. With increasingly pervasive use of SSD offload, there nothing particularly stopping you from running even the largest open models on ordinary local hardware. Sure, it will be really slow, but if you need the smarts for e.g. a one-off planning role it's a no-brainer.
