3 things to check before choosing between DeepSeek V4 Flash and PRO — Flash is 284B parameters and runs on consumer hardware, PRO needs a workstation.
DeepSeek V4 Flash vs PRO: Which One Fits Your Machine?
DeepSeek V4 arrived in two sizes, and the naming does not make the difference obvious. The gap is not mainly about quality — it is about whether the model will run at all on the machine in front of you.
V4 Flash is a 284B-parameter mixture-of-experts model. Because only a fraction of the experts activate per token, it runs far more cheaply than the raw number suggests — which is why local engines target it first.
| Model | Realistic home for it |
|---|---|
| V4 Flash | Mac with large unified memory, multi-GPU box, or SSD streaming on less |
| V4 PRO | Very high-memory workstation or a server |
Two open-source engines target V4 directly. DwarfStar was built for V4 Flash first and supports Metal, CUDA and ROCm. Colibrì runs V4 Flash alongside seven other model families and will stream from disk when memory is short.
The honest comparison is not Flash against PRO — it is Flash against the subscription you already have. Running locally removes the monthly bill and keeps your data on your machine, and costs you speed and setup time.
Pros
Cons
Look up your memory
Unified memory on a Mac, or total VRAM plus RAM elsewhere. This decides everything else.
Assume Flash
Unless you have a workstation, Flash is the answer. PRO is not a small upgrade.
Pick the engine that matches your hardware
DwarfStar for Metal and CUDA, Colibrì for everything else.
Test on one real task
Run something you actually do, and time it. Then decide whether to keep paying for a subscription.
The open weights are free to download and run. Check the specific model licence for commercial-use terms before you build a business on it.
Not comfortably. With SSD streaming it may load, but it will be slow. For a 16 GB machine a smaller model such as a 7B is a much better experience.
The weights are the same, but quantisation used to fit a model into less memory does cost some quality. A 4-bit local model is not identical to full precision.
Both local engines also run GLM-5.2 and GLM-5.3, and Colibrì additionally runs Kimi K3 at 2.8T parameters. It is worth testing more than one — they differ by task.
