Qwen 2.5 VL 的其他尺寸

Qwen 2.5 VL 72B Instruct — 常见问题

How much VRAM does Qwen 2.5 VL 72B Instruct need?

About 45 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.

Does Qwen 2.5 VL 72B Instruct run on an RTX 4090 (24 GB)?

No. Qwen 2.5 VL 72B Instruct needs about 45 GB at Q4_K_M, more than a single RTX 4090's 24 GB. It needs a larger card, several GPUs, or Apple Silicon with enough unified memory — or it runs with part of the weights offloaded to system RAM, which is much slower.

How do I run Qwen 2.5 VL 72B Instruct locally?

Install Ollama and run `ollama run qwen2.5vl:72b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.

What other sizes does Qwen 2.5 VL come in?

Qwen 2.5 VL 7B Instruct (6 GB), Qwen 2.5 VL 72B Instruct (45 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
