Frequently Asked Questions
How much VRAM does DeepSeek V4 Flash DSpark Abliterated Uncensored need?
DeepSeek V4 Flash DSpark Abliterated Uncensored requires 109.1 GB of VRAM at Q4_K_M, or 363.6 GB at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 165.3B × 4.8 bits ÷ 8 = 99.2 GB
KV Cache + Overhead ≈ 9.9 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.
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run DeepSeek V4 Flash DSpark Abliterated Uncensored?
No — DeepSeek V4 Flash DSpark Abliterated Uncensored requires at least 77.3 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 DSpark Abliterated Uncensored?
For DeepSeek V4 Flash DSpark Abliterated Uncensored, Q4_K_M (109.1 GB) offers the best balance of quality and VRAM usage. Q5_K_M (129.5 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 77.3 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run DeepSeek V4 Flash DSpark Abliterated Uncensored on a Mac?
Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run DeepSeek V4 Flash DSpark Abliterated Uncensored, 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 109.1 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (128 GB).
Can I run DeepSeek V4 Flash DSpark Abliterated Uncensored locally?
Yes — DeepSeek V4 Flash DSpark Abliterated Uncensored can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is DeepSeek V4 Flash DSpark Abliterated Uncensored?
At Q4_K_M, DeepSeek V4 Flash DSpark Abliterated Uncensored can reach ~44 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 ÷ 109.1 × 0.65 = ~48 tok/s
Estimated speed at Q4_K_M (109.1 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of DeepSeek V4 Flash DSpark Abliterated Uncensored?
At Q4_K_M, the download is about 99.16 GB. The full-precision BF16 version is 330.53 GB. The smallest option (Q2_K) is 70.24 GB.
Which GPUs can run DeepSeek V4 Flash DSpark Abliterated Uncensored?
No single consumer GPU has enough VRAM to run DeepSeek V4 Flash DSpark Abliterated Uncensored at Q4_K_M (109.1 GB). Multi-GPU or professional hardware is required.
Which devices can run DeepSeek V4 Flash DSpark Abliterated Uncensored?
