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. Longer context grows the KV cache — use the selector above.

Speed = decode tok/s estimated from memory bandwidth ÷ measured file size (× MoE active share). Real numbers vary ±30% by runtime and settings.
How much VRAM does Qwen2.5-VL-7B-Instruct need?
The honest answer: 4.4 GB at the UD-IQ2_XXS quant with 8K context — that is the measured
file size (2.4 GB) plus KV cache and runtime overhead. The smallest published build needs
4.0 GB; the lossless one needs 19.8 GB.
Cheapest hardware that runs it: Used RTX 3070 8GB (~$220, used market) — see which GPU to buy.
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 Qwen2.5-VL-7B-Instruct need?
The measured answer: 4.4 GB at the UD-IQ2_XXS quant with 8K context. The smallest published build needs 4.0 GB; the lossless (F16/BF16) build needs 19.8 GB. These are real GGUF file sizes from Hugging Face, not formula estimates.
Can I run Qwen2.5-VL-7B-Instruct on a 24GB GPU (RTX 3090/4090)?
Yes — at UD-IQ2_XXS (4.4 GB). Quants that fit 24GB: UD-IQ1_S, UD-IQ1_M, UD-IQ2_XXS, UD-IQ2_M, Q2_K, Q2_K_L, UD-IQ3_XXS, UD-Q2_K_XL, Q3_K_S, Q3_K_M, UD-Q3_K_XL, IQ4_XS, IQ4_NL, Q4_0, Q4_K_S, Q4_K_M, UD-Q4_K_XL, Q4_1, Q5_K_S, Q5_K_M, UD-Q5_K_XL, Q6_K, UD-Q6_K_XL, Q8_0, UD-Q8_K_XL, BF16.
How fast will Qwen2.5-VL-7B-Instruct run?
Decode speed is memory-bandwidth-bound. At UD-IQ2_XXS: roughly 315 tok/s on an RTX 4090, 293 tok/s on an RTX 3090, 125 tok/s on an M-series Mac with 128GB, and 15.6 tok/s on CPU with dual-channel DDR4 — estimates from measured file size, MoE active-parameter share and memory bandwidth.
Can I run Qwen2.5-VL-7B-Instruct on CPU with system RAM?
Yes, if your usable RAM is at least the file size. At UD-IQ2_XXS you need ~4.4 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 Qwen2.5-VL-7B-Instruct 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.
