Can Mac Studio M4 Max 48 GB run DeepSeek-V4.1-Flash (748B-A16B)?
48 GB unified · 546 GB/s memory bandwidth · DeepSeek-V4.1-Flash (748B-A16B) has 748B parameters (16B active per token).
Short answer
No. It doesn't fit in memory.
Needs ≈397 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 (4-bit) needs about 397 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 M4 Max 48 GB has about 39 GB left, so it’s 358 GB short.
Ways to make it work
Close everything else
Not enough on its own: with every other app closed it’s still about 355 GB short.
