None of DeepSeek V4 Flash's quantizations fit

Even the most aggressive quantization needs more memory than the Apple M4 Max (128GB) provides. Your options below: rent a bigger GPU in the cloud, or upgrade.

GPUs that would let you run this model locally:

Apple Mac Studio M3 Ultra (192GB)~$7,499

Unified memory means ~190GB of usable model RAM in a single quiet box. Runs 405B at Q4.

NVIDIA H100 80GB~$30,000

Datacenter-grade. Most users should rent rather than buy — see cloud options.

FAQ

Can the Apple M4 Max (128GB) run DeepSeek V4 Flash?

No. DeepSeek V4 Flash (291B) needs at least 310.1GB even at its smallest quantization, more than the 128GB on the Apple M4 Max (128GB).

What's the best quantization to use?

None of DeepSeek V4 Flash's available quantizations fit in 128GB. You'll need either a larger GPU, a smaller model, or to run it in the cloud.

What if I need more headroom for context length?

KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
