Frequently Asked Questions

How much VRAM does DeepSeek V4 Flash 180B need?

DeepSeek V4 Flash 180B requires 61.3 GB of VRAM at Q4_K_M, or 203.5 GB at BF16. Full 1049K context adds up to 11.5 GB (72.8 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 101.6B × 4.8 bits ÷ 8 = 60.9 GB

KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 11.9 GB (at full 1049K context)

Can I run DeepSeek V4 Flash 180B on a Mac?

Yes — Mac Studio M5 Max (48 GB) and 55 other Macs can run DeepSeek V4 Flash 180B, the smallest at Q2_K. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 61.3 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio (M3 Ultra, 96GB).

Can I run DeepSeek V4 Flash 180B locally?

Yes — DeepSeek V4 Flash 180B can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is DeepSeek V4 Flash 180B?

At Q4_K_M, DeepSeek V4 Flash 180B can reach ~78 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 61.3 × 0.65 = ~85 tok/s

Estimated speed at Q4_K_M (61.3 GB)
