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)
KV Cache + Overhead ≈ 11.9 GB (at full 1049K context)
VRAM usage by quantization
Q4_K_M61.3 GBQ4_K_M + full context72.8 GB- Can NVIDIA GeForce RTX 5090 run DeepSeek V4 Flash 180B?
No — DeepSeek V4 Flash 180B requires at least 43.5 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
- What's the best quantization for DeepSeek V4 Flash 180B?
For DeepSeek V4 Flash 180B, Q4_K_M (61.3 GB) offers the best balance of quality and VRAM usage. Q5_K_M (72.7 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 43.5 GB.

- Can I run DeepSeek V4 Flash 180B on a Mac?
DeepSeek V4 Flash 180B requires at least 43.5 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run DeepSeek V4 Flash 180B locally?
Yes — DeepSeek V4 Flash 180B can run locally on consumer hardware. At Q4_K_M quantization it needs 61.3 GB of VRAM. 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 ~72 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)
~85 tok/s~85 tok/s~72 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of DeepSeek V4 Flash 180B?
At Q4_K_M, the download is about 60.95 GB. The full-precision BF16 version is 203.16 GB. The smallest option (Q2_K) is 43.17 GB.
- Which GPUs can run DeepSeek V4 Flash 180B?
No single consumer GPU has enough VRAM to run DeepSeek V4 Flash 180B at Q4_K_M (61.3 GB). Multi-GPU or professional hardware is required.
- Which devices can run DeepSeek V4 Flash 180B?
