Can Mac Studio M5 Max 48 GB run DeepSeek-V4-Flash (284B-A13B)?

48 GB unified · 614 GB/s memory bandwidth · DeepSeek-V4-Flash (284B-A13B) has 284B parameters (13B active per token).

Short answer

No. It doesn't fit in memory.

Needs ≈118 GB but only ≈39 GB is available after the OS, other apps and Open WebUI.

Why it doesn’t fit

Even its smallest practical version (3-bit) needs about 118 GB for the model, its context memory and the runtime. After macOS (≈4.8 GB), a browser with a few tabs (≈3.0 GB) and Open WebUI (≈1.0 GB), Mac Studio M5 Max 48 GB has about 39 GB left, so it’s 79 GB short.

Ways to make it work

  • Close everything else

    Not enough on its own: with every other app closed it’s still about 76 GB short.

  • Pick a smaller model from the same family

    No smaller DeepSeek-V4 model in our catalog runs well here. See the other models below.
