Qwen3-Coder Next is also head to head with Qwen3-Coder 30B-A3B above it on the leaderboard. One more model needs much the same memory: DeepSeek-R1-Distill-Llama-70B. gpt-oss-20b is also head to head with Gemma 4 E4B below it on the leaderboard. One more model needs much the same memory: Ministral 3 14B.

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.
