KV cache uses a flat +20% context/overhead rule because this repo does not publish its config; exact numbers may differ for long contexts. MoE models keep all experts in memory — total size counts, not just active params.

How much VRAM does Huihui-DeepSeek-V4-Flash-0731-abliterated need?
The honest answer: 105.6 GB at the Q2-0731 quant with 8K context — that is the measured file size (86.7 GB) plus KV cache and runtime overhead. The smallest published build needs 105.6 GB; the lossless one needs 199.1 GB.
Can I run it with CPU offload?
Yes, if combined RAM+VRAM ≥ file size — but generation speed is limited by memory bandwidth. Expect roughly: DDR5 dual channel ~10-30 tok/s for small MoE actives, single digits for big ones, 0.1-1 tok/s when experts page from disk. CPU-only is fine for batch jobs, painful for chat.
Why do other sites show different numbers?
Most pages compute weights from a formula (params × bits/8). We use the actual file sizes published in GGUF repos, which include the embedding table, unquantized tensors, and container overhead — that is why our numbers can differ from a naive calculation.
FAQ
How much VRAM does Huihui-DeepSeek-V4-Flash-0731-abliterated need?
The measured answer: 105.6 GB at the Q2-0731 quant with 8K context. The smallest published build needs 105.6 GB; the lossless (F16/BF16) build needs 199.1 GB. These are real GGUF file sizes from Hugging Face, not formula estimates.
Can I run Huihui-DeepSeek-V4-Flash-0731-abliterated on a 24GB GPU (RTX 3090/4090)?
Not at Q2-0731 (105.6 GB). Nothing fits 24GB — the smallest build needs 105.6 GB. Use the hosted API or a smaller model.
Can I run Huihui-DeepSeek-V4-Flash-0731-abliterated on CPU with system RAM?
Yes, if your usable RAM is at least the file size. At Q2-0731 you need ~105.6 GB of RAM. CPU generation is memory-bandwidth-bound: expect single-digit tok/s for large MoE models, 10-30 tok/s for small active params, and below 1 tok/s when experts page from disk.
Why do VRAM numbers for Huihui-DeepSeek-V4-Flash-0731-abliterated differ between sites?
Most sites compute weights from a formula (params x bits/8). ModelFit uses the actual GGUF file sizes published on Hugging Face, which include the embedding table, unquantized tensors, and container overhead — so our numbers reflect what you really download and load.
