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 Radeon AI PRO R9700, 32GB. GLM-4.7-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.

Granite 4.2 30B is also head to head with Gemma 4 31B it above it on the leaderboard. One more model needs much the same memory: Nemotron 3.5 Lightning 30B-A3B. GLM-4.7-Flash is also head to head with Gemma 4 12B below it on the leaderboard. One more model needs much the same memory: Devstral Small 2 24B.

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. 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.
