reliability and self reliance is worth a lot to most. Heck, you could be the best in the world at what you do, but if you're unreliable you wont find stable employment. So, not having some amoral shady company errode model quality out from under you constantly is also worth a lot more than simple cost balancing calculations can capture.

I'm getting really sick of the constant rot and "magic breakthrough" cycle, so im going full local, at expense on paper but being able to trust something which I need to understand the reliability of is priceless.

I like predictable. I'll take slightly less capable over unreliably capable, since with reliable i can calibrate my expectations and learn what aspects of my workflows to entrust and trust it will work. You simply cannot do that with models you don't control and in my experience they will all errode after the initual marketing wave passes, likely you eventually get fed heavily quantized versions and are expected to accept degraded service when what convinced you to pay was a far superior product. No such issues with local.

Thanks. If I may ask a follow-up: how did you decide what amount of compute to buy?
