Ratings are coarse on purpose: they say what a model is usable for, not where it places to the decimal.
Side by side on the Mac Studio M5 Ultra, 256GB at 16k of context
Tencent Hy3 needs 193 GB at 32k of context. The biggest machine on this list is the Mac Studio M5 Ultra, 256GB, and it has 192 GB usable. Tencent Hy3's weights are 182 GB of that. The rest is the cache, and the cache is the part that shrinks when you ask for less context: at 16k the model needs 188 GB, which that machine holds. It already runs GLM-5.3-Flash, so at 16k of context one machine here runs both. It costs $10,799. The rest of this page is what each model does with it.

How much use it takes to pay for the machine
Everything above is at 500k tokens a day. Pay-back moves with how much you actually run, so here are both models at the five levels of use the calculator names, on the Mac Studio M5 Ultra, 256GB at 16k of context. GLM-5.3-Flash pays for it sooner at every level of use, so which of them to run does not turn on how hard you work it.

The assumptions behind both columns
Both columns use the same usage: 500k tokens a day at 15:1 input to output, 32k of context, $0.17 per kWh, and today's API prices held flat. The two sections that need one machine to hold both models are at 16k of context instead, which is the longest on the calculator's list where one does. Speeds marked estimated are worked out from memory bandwidth rather than measured, and pay-back scales with them. Where nobody rents an open model by the token, its API prices are the nearest hosted model's, named beside them. Machines are the 37 here with a published price that are still sold. Change any of it in the calculator.
