How much VRAM does Qwen2-VL 7B Instruct need?

About 5.5 GB at Q4_K_M with 4K of context and batch 1, rising to roughly 7.2 GB at 32K. That figure is weights plus KV cache plus a 10% activation buffer, calculated from the model's architecture rather than measured on a card.

Will Qwen2-VL 7B Instruct run on a 8GB GPU?

Yes — at Q4_K_M and 4K context it needs about 5.5 GB, which leaves 2.5 GB spare on a RTX 4060, or on any of the other 8 GB cards here (9 in all). That is the smallest size in this index that clears it comfortably; 76 of 78 do.

Which quantization of Qwen2-VL 7B Instruct should I use?

Q4_K_M has the lowest published quality loss (3.8%), and Q4_K_M is the level most people run. All 2 levels in the index are Q4_K_M, AWQ INT4.

This index would suggest Qwen3-VL 8B Instruct instead today — longer context (32K → 40K tokens). The numbers below are still accurate; they are just for a model you probably should not start with. Compare the two →

4.6 GBmin VRAM—accuracy

Google's on-device Gemma 4: about 4.7B parameters doing the work plus a 2.8B per-layer embedding table, a 128K window, and image and audio input. Only 4 of its 42 layers keep a cache that grows with context, so the full 128K window costs about 2.0 GB of cache. At Q4 it is about 4.9 GB at 4K and 7.0 GB at the full window — an 8 GB card runs it comfortably at everyday context lengths. Sizes here count the whole model in GPU memory, which is what a Mac or a full GPU load uses; llama.cpp keeps the embedding table in system RAM instead, so on a discrete card it needs roughly 1.6 GB less VRAM than shown at Q4. Sizes use the calculator's generic rates — no GGUF file size could be checked.

The smallest Gemma 4: about 2.3B parameters doing the work plus a 2.3B per-layer embedding table, a 128K window, and image and audio input. Its cache barely grows — 3 of 35 layers track the full context, about 0.8 GB at 128K. At Q4 it is about 3.0 GB at 4K and 3.8 GB at the full window — comfortable on any card in this index and on an 8 GB Mac. Sizes count the whole model in GPU memory; llama.cpp keeps the embedding table in system RAM, so on a discrete card it needs roughly 1.3 GB less VRAM than shown at Q4. Sizes use the calculator's generic rates — no GGUF file size could be checked.

Alibaba Qwen3.5

Consumer GPUMac / Apple Silicon

3.3 GBmin VRAM—accuracy

The 4B size of Qwen3.5, for 4 to 8 GB cards, base-model Macs and CPU-only machines. Only 8 of its 32 layers keep a growing KV cache. At Q4_K_M it needs about 3.3 GB at 4K context and 4.3 GB at 32K, so a 6 GB card is enough for long chats; its full 256K window needs about 12 GB. Reasoning is off by default on the small Qwen3.5 sizes, and it reads images through a separate vision encoder. Sizes come from the published GGUF file sizes, and no per-level quality loss has been published.

Running Qwen2-VL 7B Instruct locally

At Q4_K_M and 4K of context, Qwen2-VL 7B Instruct needs about 5.5 GB — 4.8 GB of weights, 0.22 GB of KV cache and a 0.5 GB activation buffer. The smallest cards in this index that clear that comfortably are 8 GB ones — 9 of them, from the RTX 4060 up — and 76 of the 78 cards here do. These are calculated figures, not measurements: the estimate stops counting a card as comfortable at 88% of its VRAM, which is roughly the room a desktop session needs.

What longer context costs

Going from 4K to 32K adds about 1.53 GB, taking the total to 7.2 GB. Weights do not move with context — only the KV cache does, and it grows linearly, so this is the number to watch when planning for long documents. The model's native window is 32K; holding all of it at Q4_K_M would need about 7 GB.

Which build to download

This index tracks 2 formats for it — GGUF, AWQ — across 2 levels. Q4_K_M carries the lowest published perplexity loss at 3.8%. The fastest level listed is AWQ INT4 at about 95 tok/s on an RTX 4090, batch 1 — an estimate, not a run on this site's hardware. GGUF runs on llama.cpp and Ollama across NVIDIA, AMD and Apple silicon; AWQ and GPTQ target vLLM on CUDA and ROCm; EXL2 is ExLlamaV2 — CUDA only, and now archived, so local use rather than serving.
