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

The cheapest machine that runs either model is the same one, so this is the pair doing the same work on the same hardware: Mac Studio M5 Ultra, 256GB, at $10,799.

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. MiniMax M2.7 pays for it sooner at every level of use, so which of them to run does not turn on how hard you work it.

Memory is not what separates them

DeepSeek V4-Flash needs 155 GB of memory at 32k of context and MiniMax M2.7 needs 149 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.

DeepSeek V4-Flash is also head to head with Qwen3.8 Flash Next above it on the leaderboard and Qwen3.8 27B below it. One more model needs much the same memory: Inkling Small. MiniMax M2.7 is also head to head with Ling 3.0 flash above it on the leaderboard and Qwen3.6 27B below it. One more model needs much the same memory: Qwen3 235B-A22B Instruct 2507.

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.
