Gemma 4 31B it is also head to head with Qwen3.5 122B-A10B above it on the leaderboard and Gemma 3 27B it, the last-generation Gemma nearest it in size. One more model needs much the same memory: Qwen3.6 35B-A3B. Granite 4.2 30B is also head to head with GLM-4.7-Flash below it on the leaderboard. One more model needs much the same memory: Nemotron 3.5 Lightning 30B-A3B.
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.
