Agreed. Economies of scale are about the only way this makes sense.
I was just working thru the use case for purchasing a 64gb Strix (vs the typical coding I might do using OR or Open Code Go). The ROI is somewhere in the order of 7-10 years for me. So, on a purely dollar cost basis, local inference is $$$. OTOH, from a sovereignty and "own your own code" basis...there's something to be said for it.
Probably I will run a few tests using OR with a few outstanding tickets of mine, to kick the tyres of Qwen3.8-27B. I've tried Qwen3.6-35B and frankly it's...not very good at code gen or patching.
To boot, code gen isn't the only thing I use LLM for, so I suppose it depends on how bloody minded I want to be about future use case (I do actually have one).
