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 Framework Desktop, 128GB. Devstral 2 123B pays for it sooner at every level of use, so which of them to run does not turn on how hard you work it.
| A day's use | Ling 3.0 flash | Devstral 2 123B |
|---|---|---|
| 50ka few chats a day | 44,678 years | 585 years |
| 200klight assistant use | 11,170 years | 146 years |

The Framework Desktop, 128GB generates at most 3.06M tokens a day on Devstral 2 123B, so that column's figures from 4M tokens a day up are for the most it can do, not for the whole of what was asked.

Memory is not what separates them
Ling 3.0 flash needs 82 GB of memory at 32k of context and Devstral 2 123B needs 87 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.
Ling 3.0 flash is also head to head with Tencent Hy3 above it on the leaderboard and MiniMax M2.7 below it. One more model needs much the same memory: GLM-4.5-Air. Devstral 2 123B is also head to head with Gemma 4 E4B above it on the leaderboard and DeepSeek-R1-Distill-Qwen-32B below it.
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.
