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 mini M6, 16GB. MiniCPM5 2B is never the slower of the two to pay for it, at any level of use.

Memory is not what separates them
MiniCPM5 2B needs 3.0 GB of memory at 32k of context and Qwen3.5 4B needs 3.8 GB. Every machine priced here that runs one runs the other, at 32k of context. So the choice between them is what each is good at, how fast it runs and what the same work costs on an API, not what you have to buy to hold it.
MiniCPM5 2B is also head to head with Qwen3 235B-A22B Instruct 2507 above it on the leaderboard. Qwen3.5 4B is also head to head with gpt-oss-120b below it on the leaderboard.
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.
